Steel for a knife

[mickdundee]

I've just put a new blade on my circular saw and wondered if the old disc would be useful to turn into a small fixed blade knife. I've known people say old band saw blades are good for this, but I don't know if these discs are generally a pretty low grade steel with tips.

Thanks

I would have thought they were pretty low grade. Often think I should turn one of my old handsaws into a briar slasher though, thin but springy steel.

I made a large " Bowe " type knife out of an old machine hack saw blade once . Held a razor edge but was too brittle .

I think they generally use something like leaf spring steel

Or plough breast steel would be pucker

Yeah, now you've said it I've heard that one before as well

Apparently large file's make for high quality knife making steel

But too brittle when you thin it down to an edge ....

A file takes a lovely edge. My favourite marking knife in the workshop is made from a small flat file that was for taking the rakers down. The blade would not have much flex but nought wrong the edge it takes.

An old lawnmower blade is ideal.
