had some time tonight and couldn't think of anything better to do, so i poked around in the basement workshop and came up with this little project.

i took a 6" reciprocating saw blade (for metal, course teeth) that i wore the teeth out on near the base of the blade. after buying a few blades, i figured out that i don't need that extra length. i could really get away with 3" blades (its a pretty new saw).

i ground off the teeth and some of the back side (this is one of those bimetal blades, just by the way) in order to make a stick tang for a wood handle. ground a bevel on with the bench grinder (can't wait to get my belt sander worked out) and sharpened on a course stone.

after a failed attempt at a wood handle, i cut a strip off of a t-shirt from my rag box and did a quick cordwrap to finish sharpening it and to test it out. brought the edge to 1200 grit and then stropped. edge could have used some work, it wasn't super sharp, but it was serviceable. at this point i was beginning to run out of steam...

used it to make some shavings from a pine stick, and cut a notch. the knife wasn't that comfy in the hand, but it worked.

then i used the saw to cut a notch in the end of the stick to haft an arrow tip for an emergency arrow situation (tip secured with an inner wire from a monitor-computer cable):

its rather small in the hand, and the thinness of the stock led to some flexing while using, which made it a little trickier to use:

so in the end it worked, but obviously its not the best choice. for the space it would take up, i would say its worth tossing in the bottom of a survival tin type kit. you could wrap it with a strip of t-shirt or a shoelace if you ever needed to use it.
 
oh i hadn't thought about tape. i could easily fit some feet of duct tape around the handle no problem, and it would make it easier to grip.
 
I thought of butchering a cheap wood saw to make a few blades like that, small, light, cheap, handy as heck, what's not to like?
 
I ran across that here...

Personally, I really like this guys stuff.

The good things about this home made knife...
1. It showers sparks from a ferro rod (a lot better than the striker that it came with).
2. Its bigger than a scalpel blade, but small enough to pack in an altoids tin kit.
3. Cheap to make.
4. Already has a real saw blade (small, but it IS functional).
5. It easily attaches to a stick(using the lanyard) to make a more practical tool.
 
as far as sawing goes, this saw is decent for making notches. if i had a woodsaw blade that was worn out (wood seems so much more gentle on blades than metal...) in the same way then it would have made a much better knife for woods use, as the saw would be much more effective for sawing wood.

m40's stuff is pretty cool. he comes across as a little bit arm chair expert to me but he does have alot of really good info on his site. that article that you pointed to was part of my inspiration, but i have been doing these sorts of things for a long time (making makeshift knvies from little scraps of metal) as you probably did when you were young too. another inspiration for this was an article that doc canada posted quite some time ago i think, where he took various small cutting blades and equiped them for easy hafting.
 
I've made a couple but never bothered to put handles on them because they were to easy to snap just between finger and thumb. The way I saw it though was that my hacksaw striker had an edge going begging and it seemed a crime not to sharpen it up. If I get some stronger blades I'll go at it with a bit more enthusiasm. As they stand they can quite happily sit forgotten about under a layer of abduct tape on the underside of a lid. That saves space and keeps it rust free. And I'll just wrap the bit of tape round it if I need to crack it open.
 
i have considered picking up some of the thicker sturdier blades at the hardware store to make knives like this out of, but haven't got around to it yet. i have seen some that are about 12" long...i wonder if the teeth would still cut okay in wood at that courseness
