Hollow-handled Sawback "Survival Knives"...are they really that bad?

 
Recently, a major outdoors magazine ran a short article discussing survival knives. The gist of the article, was that the writer offered his opinion that the stereotypical "Rambo" style survival knife with a saw-back blade and a hollow handle for storing a survival kit was a poor choice and not one he would make.

I kind of take exception to this position. I have both high quality and *cheap* knives and enjoy using both on my outings. And I will readily admit, I like Hollow Handle [HH] knives.  I agree, nothing beats a *quality* knife for camp and trail. You should always buy the best quality gear you can afford, even if you have to save for it. But if you cannot afford better, should that deter you from hiking and adventuring outdoors? I think not.

In presenting his discussion, the writer cited 5 points or reasons why he would not choose such a knife for survival purposes:

1. Hollow-handle, specifically, the lack of strength provided by the short tang required to create storage space in the handle.

2. Uncomfortable Grip, citing the tubular body of the handle.

3. Poor steel used in the construction of economy [cheap] knives.

4. Weird Spines. He's speaking of the saw back.

5. Gizmo's, specifically, the "survival kit" packed in the knife handle.

Now, I have a lot of respect for the writer, whom I will not name. I even own one of his books and refer to it often for information on hunting and gathering. I am not trying to be argumentative, neither am I advocating for hollow-handled knives or promoting them. Simply, I want to present another perspective on the utility of these knives for your consideration. I'll address these critical points in the same order, so here we go:

1. Hollow Handle - Tang joint strength - Admittedly, this is the historic failing in most of these knives. On the other hand, I have seen quality blades snap and fail when tasked for a job they were unsuitable for. MORA knives for example, only have a half or 3/4 tang and are a remarkable knife priced around ten dollars, and can perform remarkably well. They are the epitome of "inexpensive, but not cheap". My point is, any knife can fail and it's wise to learn techniques that lighten the knife's burden like making "small beaver chew" cuts around wood, or bending a sapling and cutting into the stressed bend. Tips and videos for proper knife technique are free and abundant all over the Internet.

2. Uncomfortable grip - I admit a tubular HH knife handle can slip around in the hand. But so can a lot of other handle shapes, dry or wet. It is sometimes useful to wrap or build up a handle using friction tape, cordage, or both. And this provides materials that are useful in a fix. Point is, that uncomfortable grip is easily remedied.

3. Poor steel - Most import "survival" knives use generic 440 stainless steel because it is inexpensive and abundant. Are their better steels available? Sure 1095, A2, D2, everybody has their favorites and each has it's demerits and attributes, but you are not going to find economy knives with these steels and 440 is a good all around performer for most purposes.

4. Weird Spine - Saw back knives are not a new innovation.  In the 19th century, several armies of the world issued saw-backed bayonets for use by Artillery and Engineer units to facilitate  removing limbs and branches in their way. Renown custom knife makers like RANDALL and JIMMY LILE have built knives with this feature. The U.S. Air Force-issued pilot survival knife has a saw back spine, as does the M9 Bayonet...so how is that "weird"? The saw back can be useful for notching, but the teeth are usually not set and thus will become stuck in wood once you reach the knife's slab sides, unless it's a saber grind. Still they will usually cut small diameter branches adequately, such as for building a primitive shelter.

5. "Gizmo's" - No doubt about it, the kit supplied in most inexpensive survival knives is of dubious value. They are often composed of a single adhesive Band Aid, a couple of fish hooks, a bit of mono filament fishing line, some lead sinkers, a few matches and a piece of striking paper, and sometimes a needle and some thread. The kit shown here is typical, and came with an HH knife:

Typical "Survival" goodies
 
I usually change out the "survival kit" and replace it with a few legit storm matches, water purification tabs, and some petroleum cotton balls for fire starting. Knifesmith Iz Turley [TURLEY KNIVES], of whom I am a great fan, did a couple of outstanding videos on HH and saw back knives on YOUTUBE. In his HH knives, Mr. Turley carries a length of drinking straw, water purification tabs, and a zip-loc bag, because potable water is critical in most emergent situations [assuming you can even find water].
 
Another "gizmo" usually found with these knives is a compass ball, set into the handle cap and held in place by a threaded bezel:
 
Cap compass
 
Usually, these compasses work very poorly, and sometimes not at all. Interestingly, this one works surprisingly well and is accurate. I would never rely on a compass such as this for land navigation purposes , and strongly suggest you should have a reliable, quality compass in your trail bag when afield. Still, it can be handy having a second compass available as a backup and also to confirm direction if doubtful.
 
The HH knife pictured below was a 6 buck purchase from HARBOR FREIGHT and, yes, not long after purchasing it, it broke at the blade/handle juncture while chopping a branch:

Harbor Freight Survival Knife
 
I repaired it using metal weld epoxy and its doing well so far, but it would not be my first choice for a serious outing, say a multi-day backpacking trip....but then again, who can say when a short day hike might turn into a serious event? And as stated before, ANY knife can fail. If the handle snaps, IMPROVISE...sandwich it between two slabs of wood and tie it together with paracord...not a lot of difference between that and a Neolithic stone knife assembled with sinew/antler handle. It'll work in a pinch.

Since I have an upcoming camping trip at Fremont Peak State Park, I decided planned to field test an HH knife my daughter gave me a couple of years ago. Called a ROCKY MOUNTAIN SURVIVAL KNIFE, its a generic "AS SEEN ON TELEVISION" type product:

Clam-packed knife
 

Rocky Mountain Survival Knife
 
It think new they sell for perhaps $16 dollars and come complete with sheath, a signal whistle, ferrocerium rod and striker, and the requisite sharpening stone in a pouch on the body of the sheath.
 
Extras included with RMSK
 
There was heavy rain on and off all day, so I spent today indoors putting together kit for my upcoming weekend trip and tuning up the ROCKY MOUNTAIN knife. It took about 2-3 hours on my stones, but the blade took a razor sharp edge [I have the cut finger to prove it...it's a clean slice so it will heal quickly]. The saw teeth were rounded and dull. Seen below, the left side shows the teeth after sharpening, and the original [dull] configuration are the last 3 teeth to the right of photo.

Re-profiling saw back knife teeth
 
Admittedly, even sharpened, these teeth won't saw anything, but can be used for scoring or notching wood projects. I tested on some tinder and found they work surprisingly well with a ferro rod
 
Looking inside the plastic handle, it appears the tang is held by nothing more than a fat plug of epoxy:

Epoxied tang inside handle
 
It won't handle hard use, and might not even last through this trip. We shall see. I'll be taking this knife with me later on this week and will try it out on some simple camp chores. Nothing serious, just me having fun. I'll take some pics to include in a trip report blog post next week.

In closing, I'd like to share a few final thoughts. There is nothing wrong with having a knife professionally sharpened, but you need to be able to sharpen a knife in the field. It's going to dull, and if you can't or won't bother to learn how to sharpen, then perhaps you should find another hobby, so practice!

Having a knife and using it in the field requires that you have a First Aid Kit [FAK]. It is not a question of whether you will ever cut yourself but when you will cut yourself. Not having an FAK in camp or on the trail is dumb, but especially foolish when working with sharp tools like knives and axes. Accidents happen!
 
Finally, the choice of a knife for a camp and trail tool is a highly personal decision, based on anticipated tasks and your personal experience. It's an evolving process and your choices may change many times over the course of your outdoor experiences. I think anything that gets you outdoors and enjoying nature is a good thing, so if carrying an HH gets you outside and makes you happy, I say do it. Don't worry about what people think....we all do too much of that already.

Happy Hiking!

Mock Venom Extraction Study

As a follow-on to yesterday's day hike Rattlesnake encounter: Had some discussion with friends today about the worth of those pocket Snake Bite kits sold by COGHLAN'S and other outdoor gear companies. Lots of opinions out there.

One friend, a former Medical student, sent me a link to the following article:

CLICK HERE >>>PubMed: "Suction for venomous snakebite: a study of "mock venom" extraction in a human model"


The article describes a scientific test to determine how much venom one might be able to extract.

In the testing, a SAWYER'S extractor was used. It's an easy read and may shed some light on these devices which, may have more psychological value to a patient than actual medical value. At the same time, it is not accurate to say the device does not work. Anyway, you can read it for yourself and draw your own conclusions.

Froom Creek Trail Hike - Irish Hills Open Space, San Luis Obispo

Today was a beautiful day here in San Luis Obispo. It was Spring-like, sunny, warm and temperatures probably in the mid to upper 70's...good snake weather. My friend Tom, a member of the San Luis Obispo County Sheriff's Search & Rescue unit suggested we go for a hike on the Froom Ranch Trail in the Irish Hills Open Space. We parked in the southwest corner of the COSTCO shopping center from where we would enter the trail from an opening in the corner of the parking lot:

"Unofficial" Trailhead
 
View from the trail above entry point
 
This is an unofficial trailhead, and a quick and easy way to tie into the Froom Ranch Trail, which otherwise would have to be accessed at Madonna Road or from the Johnson Ranch Trail connector [a 5 mile hike]. Our plan was to hike Froom Ranch to the King Trail, up to the Canyon View Trail, down to the Froom Ranch and back around to the COSTCO entry for a round trip of 2.9 miles:

Trail highlighted
 
Prior to starting, I checked my gear over and clipped the zippers on my pack closed using little carabiner snaps. If you've done any hiking with a pack, you may've experienced having the zipper work their way open, or worse, losing gear along the trail. This will help prevent that from occurring:
 
Clip your zipper pulls shut
 
Tom likes to make hikes into a training and conditioning opportunity, so he wore his snake gaiters. Don't laugh! A Ventura SAR member was snake bit a few years ago and the medical care cost 1 million dollars and 70 vials of anti-venin!
 
Mike leads the way.
Please notice the snakebite gaiters
 
As we ascended the Froom Ranch Trail to the King Trail, a gentle, cool breeze stirred occasionally, cooling us off. There were also shady groves of oaks of cool greenery to rest in:
 
Crazy Cool
 
As we passed over a footbridge into the oak woodland I heard Tom call out, "Snake" and saw him come to a stop. I came forward and saw a large adult rattlesnake resting on the hillside next to the trail, beneath an oak:
 
 
Pacific Rattlesnake
 
Pit Viper with heat-sensory head organs
 
Rattles. They get a new bead every time
They shed their skin. 
 
The Rattlesnake was very content to lie there and didn't even bother to rattle. We wished him well and passed on and continued our hike, warning to City Rangers we encountered. just up the trail.  The wildflowers were blooming and were gorgeous:
 
Nature's beauty
 
On top of the King Trail atop the ridge, we were treated to a nice view of San Luis Obispo's trademark peaks, the Morro's:
 
[L-R] Cerro Romauldo, Chumash, Bishop, and
Cerro San Luis [Madonna Mountain]
 
As we enjoyed the view, Tom took the opportunity to check his GPS device and benchmark our location as he mapped the route. The route we followed is one of 3 stepped fitness and conditioning courses [the other 2 are on Cerro Alta Trail near Atascadero] and requires team members to carry a #25 pack load:
 
Checking GPS
 
We moved on, dropping down the Canyon View Trail and tying back into the Froom Canyon Trail. The hike down the canyon was rocky and sun exposed. At this point we were both starting to hit our canteens often:
 
Froom Trail, looking back up the canyon
 
There were some unique gnarled dried, wood pieces along the trail:
 
Desert Wood
 
Tom called out that he could hear water running, and presently, he pointed out two streams trickling down the canyon wall opposite of us. I wondered if they might be supplied by a spring on top of the ridge?
 
Water!
 
The water reaches the stream bed in the
Canyon bottom
 
The hike was done at a leisurely pace with plenty of stops to observe nature and listen. It took us about 2:20:00 to cover the nearly three mile course [Sheriff's Search & rescue allows 3 hours to complete the course], and would be a great short hike for anyone. Of course, always carry water, wear sunscreen and a hat, and keep your cellphone handy. If you are visiting the San Luis Obispo are and want to hike our local trails, drop me a message and I will connect you with some links for download trail maps.  Also, check out my FACEBOOK page [Bushcraft Woods devil] for interesting hiking & camping tips and links.

First Hike of 2016 - A Rainy Day Hike on the Coon Creek Trail

So today, I had the day off. I decided to go out and do my first hike of this New Year 2016. I decided to hike the Coon Creek Trail, which is a favorite of mine. It is not too far from home, but is also a trail I spent a good part of Summer 1976 on as a member of the United States Youth Conservation Corps [Y.C.C., forerunner of the California Conservation Corps]. We maintained the trail and built several foot bridges over the creek before they were washed away by an El Nino' in 1995.

It was raining on and off during today's hike, and at one point I had to shelter up under some Oaks when a big squall passed over. Once I reached the end of the trail I used a 5X7 tarp to set up a hasty shelter and make something hot to eat. It was a great outing!

Mykel Hawke's "Hawkechete"...a unique and rugged woods tool.

About a year ago, I received a Mykel Hawke designed "Hawkechete" [hawkebrand.com] as a gift. Mykel Hawke is a former Captain in the U.S. Army's Special Forces, a survival skills instructor, author, and host of television programs such as DISCOVERY CHANNEL's "Man-Woman-Wild". He has brought his experience and outdoors knowledge to the table and designed some unique and unconventional woods tools, the Hawkchete being one.

"Hawkechete" processing kindling

The Hawkchete is, as it's name implies, a machete. It is constructed of carbon steel and weighs a little under 2 lbs. The blade has a black epoxy coating and is about 18" in length, with an overall length of about 23.5" including handle. the handle is a black rubber material and is "Universal" in shape, meaning it is the same shape in the hand regardless how it is held. It incorporates a lanyard hole and a short double guard to prevent the hand from sliding forward onto the blade.

The blade stock is 5/64" thick by my measure and is somewhat flexible, like any machete. The Hawkebrand.com website states the machete is built by CONDOR, a very reputable tool and knife company located in El Salvador.

The most unique feature of the machete is it's unusual shape and cutting angles. It offers the user two choices...held in one way it presents as a Khukuri stye blade. Reverse it and it presents as a Parang style machete blade. The cutting edge of the Khukuri measures at  about 17" while the Parang measures 13" of cutting edge.

All edges are razor-sharp. No, I don't mean very sharp; I mean RAZOR-BE-EXTREMELY-CAREFUL-SHARP! The Hawkechete has cutting edges both top and bottom and if you are using one you must be aware that it will cut in two directions, forward and backswing, so extreme care must be used when working with it.  This is especially true if the blade becomes stuck in wood; if you try to free it forcefully, it can suddenly come free and a sharp edge come at you or someone beside you. This is not a criticism of the design! Just an advisement to slow down and plan cuts and think your actions through, just as we should with any edged tool....the last thing one needs is a serious laceration when one is far afield and immediate medical care is not an option.

Since I was planning a camping trip for next week, I decided to get a jump on it and use the Hawkechete to make kindling for starting my campfires. Since the Hawkechete is double-edged, batoning isn't an option, so I used it like a small splitting camp axe, biting into the wooden log and then pounding the log on a stump and driving it up through the blade. Oak, Eucalyptus, it didn't matter....the Hawkechete split them all and maintained it's edge throughout. I managed to fill a 5 gallon bucket with split kindling.

After an hour of banging away with the blade and annoying the neighborhood mutts, I found no loosening in the handle. For the most part the blade was unharmed except for two very small dents which may've been inadvertent contact with the concrete pad below my stump anvil. 

I then decided to try making some curled shavings. Near the handle the blade becomes narrow-waisted and slightly curved with a straight 3" section. It is only sharpened on the inside and is ideal for use as a draw knife or for carving. Using this section I was able to produce curls for a tinder nest. Unfortunately, I was unable to ignite the curls using my ferro rod, buts was able to do so after adding some shredded jute to the nest. One could easily craft a feather stick using this feature.  

In conclusion, I would opine that the Hawkchete is a unique, unconventional, and useful woods tool, but that it must be used with the caution due any double-edged blade. I would recommend that anyone considering purchase of a machete try as many different patterns and sizes as they can access and find that which best suits their purposes.

Below, I have placed two videos made today using the Hawkechete and discussing it's features, and making fire with wood shavings processed using the Hawkechete. I hope you find them useful and informative.

Coon Creek Trail day hike with KILIMANJARO GEAR

Had the day off so I took a dayhike on the Coon Creek Trail in Montana de Oro State Park. Carried gear in my Kilimanjaro Gear deployment bag and used the Kiligear BALLAST multi-tool on the outing.  Trailhead coordinates: N 35 15' 2 8.41" W 120 53' 12.44"  .  A great outing, beautiful day, sunny and 79 degrees Fahrenheit. Best of all, no snakes!

Make your own walking stick...it's easy!

A few days ago I was working at one of the park's I maintain, when I noticed a sapling laying on the ground.  Upon closer inspection I discovered it was a Sycamore and had been snapped off near the base. The sapling had stood in a shelter location, and it has dropped it's leaves, so I am pretty sure it was a deliberate act of vandalism and not an action of wind.   I notified my supervisor and then set about cutting up and removing the tree.

Vandalized sapling
 
Removing the branches, I got down to the trunk and it occurred to me that the tree might be useful for a walking stick. I thought I could make it into something equally beautiful and useful, and in that way, it would have a small victory over the vandals that snapped it off. Having policed up all the branches, I put the trunk aside in the bed of my truck and went back to other duties.

Having a hiking stick on trails is very wise. It can be used to balance oneself on loose or steep terrain. You can use it to drag dropped articles back to you, rather than reaching into brush and getting snakebit or stung by nettle. Finally, it can be used as a means of defense against predators. Even the aboriginal peoples here in California understood their usefulness and made walking sticks for their elders. I have made several and been talked out of a couple by friends, so I am always looking to make extras. 

Trunk before being roughed-out
 
Today I decided to set about making the walking stick. I began by removing the bark and roughing out the shape using a Bolo knife. This is a very useful blade. The heavy belly of the blade is an excellent chopper and it was easy to remove large, tough knots along the trunk. The narrow recurved waist makes an excellent drawknife blade for carving and shaping. The holes in the Bolo blade allow a grip for use as a scraper and removing the remaining inner bark.

Roughed out shaping complete
 
Having shaped it out in the rough, I set to work with a 4-in-Hand wood rasp refining shape and then smoothing the roughness out.
 
Having completed that I used sandpaper to smooth the stick. I like my trail stuff a little rustic, and so I do not go overboard and sand until a glass polish is achieved. After all, it's going to get dropped, nicked, scratched, and dented with use. I just want it functionally attractive.
 
Having sanded it to my satisfaction, I used a pencil to draw a creeping vine pattern on the stick, which I then woodburned over.
 
Penciling a vine pattern
 
The final step was to apply a coat of OLD ENGLISH wood oil, and that really brought out the glow.
 
The finished stick!
 
I am very pleased with this finished stick. It measures about 48" overall and I would place the weight at around a pound or a little over. It has a nice rounded heavy end near the top, which will serve nicely as a cudgel were I attacked by a dog or other animal on the trail.

 
Close up detail
 
Tomorrow I will seek a rubber chair tip for the end and it will be ready for the trail or street!
 
 
Happy hiking!
