Well, I knocked out 'bout half a dozen of my new fixed Blade.
I'm ready to unveil them in Atlanta.

This particular model was designed due to a general lack of functionality in knives for river guides.
I spent quite a few years a whitewater rafting guide on the Kern River in California.
I always hated all the guide knives that were available, and got sick of losing them all the time.
It's the same with all the other guides I know.
The problem with most of the knives is the retention system, they ALL suck. Period. At least all of them we have seen.
Either the retention system is weak, and you lose your knife regularly, or the retention works, but you have to remember how to unlock the damned thing to deploy it.
I don't want to be trapped under my boat, drowning, and have to remember how to deploy my knife.
That would SUCK.
The mechanism on this knife is designed so that it is positively locked, yet requires no thought as to how to deploy it.
The simple act of grabbing it releases it from the sheath!

Also, loads of the knives marketed to guides have a blunt point.
That is asinine.
In all the years I spent on the river, I know of 3 times a knife was used in an emergency.
2 of those times were cutting through the floor of a boat.
Once from the top down, rescuing a trapped customer, the other from the bottom up, a guy saving himself.
If either of these people had a blunt tipped knife, there would have been a drowning.


The 1st revision of this knife is designed with a chisel ground, tanto point.
A very strong, and very piercing tip. Specifically designed to slice right through the thick Hypalon many boats are made from.

The flat backside makes a real nice Peanut Butter spreader. (The most typical use of a guide knife)

The sheath on this revision is made from ABS plastic. It is one tough plastic. I have discovered its chemical resistance is lacking, so the next revision will use something else. Fortunately, on the river, we seldom encounter many bad chemicals.
Ideally, if this knife goes into production, they will be molded from some sort of high impact, UV/Chemical resistant plastic.
There is a detent, or pawl like flap in the sheath, pressing against the blade, keeping it from rattling.
I hate it when knives rattle.

I've started the patent process on this mechanism, and have received a provisional patent on it.
This mechanism could have an awful lot of different knives for different applications built around it.
I envision knives for Military/LEO, Search and Rescue, Swiftwater Rescue, etc...

The orange handled knife in the photo's has seen some time on a lifejacket now.
I spent the day kayaking the day before yesterday, and she made the trip.
I even had a pretty rough, Class IV swim, and she came out AOK.
Sliced my bagel, salami, and thumb like a champ too!

I love innovative ideas and when you do something in a drop, spear or clip point, I will be very interested. I don't care for tantos.
 
Those are awesome!! Since I understand the purpose for those, a tanto point makes EXCELLENT sense.

I wish I was going to Blade to see these in person!
 
Questions have been raised about testing the system, and what I have done to test it.
The answer is not a ton yet.

I have done some though, and here it is.

The 1st thing I did with the very 1st one was hang from it.
I am a 230 man, and it didn't fail.
There are stress marks on the sheath , but it held me.
I haven't tested the mounting patch on a PFD, but I feel pretty confident IT would fail before the lock did, losing the whole damed thing, and ruining a PFD.

Another thing I have done is annoy the wife by incessantly playing with one all night. I do this regularly, seeing if there is wear on the mechanism, and seeing if the spring fatigues (sp?).
I am sure I am up to several thousand cycles on my knife now, and once it broke in, and found it's happy place, there has been no wear on the mechanism.
The spring feels as good today as it ever did. (I should test the next one with a guage of some kind)

I have guys working the water with them as we speak.
They are on full time guides here on the Kern right now.
So far, everyone loves them. There will be minor tweaks as it evolves though of course.
I personally had a rather long Class IV swim wearing mine, and I still have it, and I know of a guy that took a Class V swim and didn't lose it.
These guys jump off of large rocks several times a week (30+ feet), and it's held up. (we lose a lot of knives jumping off of rocks)

In the werks is rigging one to a paint can mixer to see if we can shake it out.
I'll get pics.

What else would you folks like to see?
 
Wow, that is a very good test of the locking system of the knife. Do you have the specs on the knife, blade steel, handle material, thickness, length, ect? I looked on your web page but didn't find anything.

Also what material are you using for the spring, I would hope that it is not steel as that could rust and be very hard to oil/clean.
 
7-7/8" OAL
8-1/8" Sheathed
3-3/4" Blade Length
5/32" 440C
Handles are 1/8" slabs of G10 or Carbon Fiber.
The spring is an integral part of the tang.
I had to differentially heat treat the steel to get a spring temper on it.
I'll try and get a pic of one without scales so you can see the mechanism.
As a matter of fact, the only one I have right now, the original proto has no handles. It's simply a piece of steel, and a pin.

There is nothing to oil..
The hole that looks out of place on the handle is there for cleaning purposes.
It's a rinse hole for any dirt/grit that gets in the slot.
A stick could foul the mechanism, but crud should not.
 
This concept has potential! Maybe also some other blade shape (sheepsfoot?) and it would make a great marine knife. I work in a dredging company, and I'm getting on and off ships all the time (pilot ladders etc...), so a good stainless knife with a sturdy safe sheat is always apreciated.
 
Id trap that to my BCD in a heartbeat
It works pretty good on a BCD, though in the future, for dive specific knives, I will make the sheath a little more dive friendly.
The slots in the sheath were put there for rubber strap rigging to my leg.
They are a bit close for that though it turns out.
I rigged it to my BC, and all was well.

There are quite a few other blade designs on the drawing boards.

This one came about 1st because it was the inspiration for the mechanism, and because it's whitewater season now.
I wanted guides torture testing the mechanism ASAP, and that's what's happening.

Life on the river is tough on equipment (and people)
I'm getting feedback on about 200 miles of carry, and 150 hours a week right now.

A reverse Hawkbill will probably be next, as I have had several requests from rescue types who mainly are using pull cuts.
Especially in swiftwater, most cuts will be a pull cut.
A reverse Hawkbill will be safer for the victim, and easier on the rescuer.
