If it is heat treated spring go ahead with the torch. If it is annealed stock the torch will tend to harden the cut line.
So if it is annealed and you don't have a band saw, I used to mark out the profile and drill a sieries of holes along side each other almost touching, then used a rod saw or chisel to cut the joining bits.
I used to start at the opposite ends of the profile so that the steel was not getting too hot. after a lot of drilling I sometimes had the steel start to harden. I was obviously not driling with coolant or for that matter probably not the right speed. But it worked and I got some big bowies. Gave them away like a mug.
