Awhile back i was buying some knives from a guy on ebay who made these type knives. They were very reasonable and i used them to practice making sheaths with. Well he started selling supplies also so i picked up some sections of blade he put up for auction. Being fairly new at this i decided to try and make a few since it was something different that i had not tried before. I grind the sharp teeth off with a bench grinder first then take it to the belt. Getting that cut in the wood the correct size took a little practice also. These blades are about .060 inches thick and are very tough. Used a carbide bit for the holes. You can bend them quite some distance before the break. When i looked at the break the structure was very fine. Some pretty nice steel with minimal grinding to do for an edge. I will pass these on to some deer hunting buddies after completion. I have some knives i use in the kitchen with this steel and recently resharpened them with some Japanese water stones. They take on a nice patina and stay sharp for quite awhile. Another bonus is you do not have to heat treat either.
