Making knives, stock removal with a saw blade is easy enough. If you take is slow and don't overheat the knife, you can do it without a heat treat. You really need to know the steel to know how to do the heat treat. Concrete saw blades are what I have used with many a Boy Scout group.
You can buy the pieces parts from a knife supply place, and starting with a known steel, it will be softer and easier to work, then you can send for heat treatment.
PM me your address and I will send you some pieces of band saw blades and some concrete saw blade pieces if you want something to practice on. I've made some really nice and really sharp blades with it before.
If you are looking to make yourself a coffee can forge for heat treat, I have the wool, burner and stuff for that. When I was in Boy Scouts years back, I had 4 or 5 little coffee can forges going for the scouts, with hammers and Harbor Freight pliers for tongs. We made flint and steel striker knives out of garage door springs.
In fact, I have a partially finished forge made out of a commercial freon bottle as I think about it.
Happy to help you set that up if you want.
