No, these are mechanical hacksaws - as far as i remember they look like a regular hacksaw mounted on a machine, but the blade is thicker and longer.Quote:

No. Here's the definition from Wikipedia: Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting.Quote:

A.s. just looking at your signature gives me a headache!
alright,here's the start. found an old file and started grinding and shaping w my angle grinder. took about an hour to get it this far. The handle fits my hand pretty good as far as the curves go. The blade may change shape/size as I go. This is a first for me,but so far I like the feel of it. The weight seems to be real nice and seems to be well balanced. It hit point first from 5ft when I threw it at my cat. LOL.J/K...?

Not bad at all Hawg... well, except the cat part.LOL A file is definitely hard enough. You probably already know this, but a file is also brittle, so I don't suggest dropping or banging it.:eek:
LOL That's not even some of the hard stuff.:eek: I'm glad that class is over.:cool:Quote:

So far so good, Hawg! The hard part will be the heat treating :( That's why i prefer to buy ready blades or reshape old ones. Just don't have the equipment to forge/heat the blade. By the way you'll have to drill somehow the handle before the heat treating- i think laser or water-jet cutting will do the job easy.
I'm going to use oak for the handle. I can fet a 1/4"x2"x12"L chunk at Menards for less than $5. The drilling part I can do w the neighbors drillpress. So far,I can't find anyone w a belt sander to get the blade all pretty. I found a couple tutorials on another sight for the heat treating and am confident I can do that. Still searching for a belt sander at the moment. Definately don't know anyone w a waterjet. LOL
see there ya go...got a good start on it.. Just watch the heat build up when grinding...do not quench in water...air cool only. water jet will do it all drill holes, shape blade , handle all but taper to knife edge.... and yes no using this knife as a prybar when its done....
