I grind blades for fun... I can make you them. All you need to forge a decent blade is some stock- old leaf springs work well, a hammer- $10 at the hardware store, and something to hammer on- I have used- a BL log, a railroad rail piece... I currently use a rock for big stuff and a bulldozer tooth for smaller(knives). Works great, I have a 5 pound smithy hammer.
Only issue is that I do not have a lot of steel. Plus B-teeth are rather brittle... the old ones are.
Nice knives.
I like them. Old saw blades(circular saw blades are fun) make good knives too.
