What is a Jake Knife?
It is a firefighter's tool, intended to provide the firefighter with a large , crude ,
strong knife with limited combination tool features. It is as large as possible and still
fit in the normal trouser pocket of a firefighter's structural PPE.
"Held" closed, it is just over 9" long, 1-3/4"wide and 7/8" thick.
Locked open it is just under 16" long.
The blade "Held" closed by a spring loaded ball bearing on a hole in the blade. To
open the blade just pull it open. To get the last 10 degrees of travel, to full open the
liner lock must be pressed.
The blade is locked open by the liner lock. To close the blade, press the liner lock,
then pull the blade closed. There is a safety stop at 90 Degrees closing. To get
beyond 90 degrees the liner lock must be pressed again. The blade is very heavy
and very sharp. The 90 degree safety stop feature gives the firefighter a second
chance to control the blade and close it safely.
Why call it a Jake Knife?
On the east coast of the United States of America a well qualified firefighter is called
a JAKE. This tool is intended to be of use to a JAKE
Where did this idea come from?
The idea for the JAKE KNIFE came about after I, Tom Horne, answered a call for
volunteer firefighters for the Spokane County fire district I live in. During Fire
Academy training they were always impressing on us that we must stay oriented and
aware on the fireground, but that bad things can happen leading to Mayday
situations where you are lost or, trapped and running out of air, in the dark, in dense
smoke and with the floor covered with debris. The first time I was in such a
simulated condition, I misplaced my axe while wrestling hose, and could not find the
axe again. Since in real life I am a mechanical engineer I just naturaly figured I
needed a special tool, a heavy, crude, strong tool in my pocket that I could use to
hack, cut and pry in the absence of my axe. I have now made 100 JAKE KNIVES and I
am hoping to find some firefighter tool junkies that think they need one of these
things.
What can you do with a Jake Knife that would make it of use?
A firefighter has only two hands, in heavy gloves, probably occupied wrestling a
charged hose and /or carrying entry tools. To save trips back to the truck a few small
throw away tools are usually carried in pockets of turnout coat and trousers. Their
small size limits the amount of brute force that can be applied. The JAKE KNIFE is
for tasks requiring more force than can be applied to your throw away screw driver
or pocket knife, but more finesse and accuracy than is possible with and axe or
Halligan. The Jake Knife is intended to replace your throw away tools and fill the gap
between them and a set of Irons.
Cut stuff and hack stuff.
What stuff? As supplied, the heat treated 440C Stainless Steel knife edge of your
JAKE KNIFE is very sharp and will make short work of seat belts, rope, fabric,
anything you would use your knife on. The blade will hold its edge as well as or
better than a high quality hunting knife. The cutting edge is easy to resharpen, on a
bench stone.
In addition to regular knife chores, the JAKE KNIFE is big enough and heavy enough
to be a pretty good hatchet. You can chop through house framing lumber in
situations where you can't bring an axe to bear, such as when you are on a short
ladder and can't lock in, or you don't have an axe.
You can chop through de-energized house wiring. You can always embarrass your
self and tear things up hacking at house wire with your axe, or pull out your
lineman's pliers and cut them a few at a time. With a JAKE KNIFE, to chop through
wiring just gather up a bunch of hanging burned wire and hold it against a stud and
make your chop. Otherwise, for intact cable make your chop near a support, such as
where it penetrates a stud.
If you really need and axe to hack something, and don't have one and can't get one
quickly, a JAKE KNIFE in your pocket is good insurance.
Nothing is perfect or indestructible. It turns out that hacking with a heavy folding
knife is very tough duty. The energy from the striking blow must be absorbed in the
folding joint, the stop bolt and the liner lock. After a couple hundred full force
blows the liner lock spring will be deformed so that it will be difficult to close the
blade and also the blade lock up will be sloppy, but the blade will still be locked open
and useable. Keep in mind, a couple hundred full force blows can do a lot of work.
To fix this situation, disassemble the knife and replace the liner lock with the spare
provided. This should restore the JAKE KNIFE to full function and tighten up the full
open lock up. At your leasure, a little judicious hammering can restore the original
liner lock to the proper configuration for reuse, or order a new liner lock and
shoulder bolts if you prefer.
Pry Stuff
AT A HOUSE FIRE
If the situation does not justify the destruction inevetable with a Halligan Bar, try
prying with the chisel point of the JAKE KNIFE. With some judicious restraint, a JAKE
KNIFE can be driven into a crack and used as a light pry bar to open windows and
cabinets and drawers. Think CUSTOMER SERVICE !
AT A CAR WRECK
Use the JAKE KNIFE to reach in and try to disengage a jammed hood latch before
bringing out the big tools. Pry off the negative cable on a post & clamp type
arrangement.
Turn Stuff -- Hose Couplings and Gas Valves
The solid Aluminum striking butt of the JAKE KNIFE incorporates a spanner hook
sized for turning hand line hose couplings and domestic gas meter valves.
Looks kind of knobby, won't it wear a hole in my turnouts?
It is knobby, due to the use of through bolts for the pivot and stop bolts in order to
develop the strength needed for hacking and prying. Indeed it will wear a hole in
your turnouts. For that reason, the JAKE KNIFE is sold with a SCABBARD that fixes
the tool in the turnout pocket and minimizes wear on the turnout pocket. The
SCABBARD also has a slot for a pair of heavy lineman's pliers or similar size tool. The
SCABBARD uses Velcro to lock it in place in the turnout pocket. See the SCABBARD
page.
