M40 Project - 10 Cent Survival Knife
Clever, but your thumb is in contact with the serrated edge!
Needs to reduce the serrated area.
Hack saw knife
There was an artical in out door life magizine a couple mounth,s ago on this same hacksaw knife
Cool, thanks for the link. I've got some broken blades in the basement to try this on.
Ok, here's what I've got. I used a reciprocating saw blade instead of a hacksaw blade. These blades are much thicker and stiffer than hacksaw blades. Out of my used blades I also chose Milwaukee over the dewalt blades. Again, the Milwaukee blades were thicker and stiffer than the dewalt blades I have.
I used a bench grinder and dremel tool to shape it. If you haven't tried the quick detachable wheels for your dremel you really need to, I probably would have broken off at least 3 maybe more of the little bolts that thread into the standard mandrel. With the quick attachment I had no problems whatsoever.
Using the reciprocating saw blades the thumb placement area cover on the serated part that FS brought up above was even more important so I wrapped the handle with trot line.
I used an old knife I keep in the basement for misc cutting to get the shape.
Here it is, didn't turn out to bad for a just under an hours work including paint and wrap.
what I started with
Pretty much done, yeah I know I need to repaint it with something else.
Very nice! Have to give that a go on a future day off. Sounds like a good project once winter sets in.
That would finish it
You're right about that. I'd think all he'd have to do is use that sander to grind the teeth off in an area where you'd rest your thumb.
I never thought about using a hacksaw blade this way. Clever indeed.
I made a few a couple of years back for my survival tin,but I don't carry a survival tin anymore so I keep one on my desk in the office as a letter opener.
Fun to make though and Im sure they would come in usfull if that all you had at the time of need.
I plagiarized PCC (take that as a compliment
Used a blade from a keyhole saw(I think. It was lying around, so not sure). I was going to put wooden scales on it but figured that para-cord would be more helpful in a survival sit.
Mostly done on a bench grinder. Started with a belt sander, but found the bench grinder easier to manage.
Having some trouble getting it really sharp. Any suggestions are welcome.
Definately useful idea and cost friendly. Thanks
I "saved" ( ok "scrounged") a lot of old broken blades from the shop's metal band saw. Even though the blades snapped, they are still sharp and still cut right thru steel! I'm going to punch some holes in the ends of a couple that will fit nicely into the wood saw's "bow" frames I have for trees and limbs....
I am working on making aluminum handles for a couple more!
Keep those old blades!
You can also use the hole in the end of a hacksaw blade to run a rivet through to pivot on and fold a heated piece of PVC pipe around and make a simple folding/pocket knife. Wont lock open or closed but a little tension and they work OK for little stuff.
I always thought that a bandsaw blade could make a wicked weapon.
Put a handle on one end and use it like a whip!
very cool little knife ill have to try that
