I want to try out MAPP because it's difficult to keep a large piece of titanium red-hot with the propane torch, but I don't want to spend another $80 or so on a torch head I probably don't need. I also don't want to blow up a MAPP canister and have to be in hospital for a week while they fish pieces of canister out of my chest cavity.
I will confirm that the yellow canisters with the false term 'MAP' are NOT MAPP gas. The first time i realized it was when I was soldering some copper pipe joints then after swapping the yellow tanks from MAPP to MAP that the time to make the solder flow was noticeably longer.
They continue to sell yellow canisters because the profit margin is exponentially higher. There is no noticeable difference in time for melting something between using a yellow canister and a blue propane canister.
You won't blow up a yellow canister. Theyre designed to work with anything with a compatible attachment fitting.
Buy a cheapo harbor freight torch....the big one...for like $30...hook it to a 20lb propane tank...then surround the knife in firebrick to keep the heat somewhat focused.
I use a similar method....cept with an actual furnace...to melt aluminum and copper. I just use a literal cooking pot to melt lead.
