Just got done making a 1600's safety spring today, on top of many in the last 10 years......
I use 1095 in the annealed state for starters, as it is very tough and very forgiving IMO.
I machined a Snaphaunce safety spring, bent it to desired shape using MAPP gas, then went through a simple process.
I bent the initial shape by getting it just getting to "Light Orange" without any sparkle and just progressively getting it to the desired form.
I then sanded with a fine file and 220 grit to get a blank canvas so to speak, then took it to just a bright orange right past cherry- 1095 can handle (and likes IMO) a water quench (motor/linseed etc.)is not "fast" enough and cools too slowly. Certain alloys like an oil quench, but 1095 works great with water. I then hit with 220, and bring it to a blue/gray, and let the gray color just sneak up on the blue before I stop the heat and let it air cool.
1095 is extremely forgiving, and super tough when done right.
This is just the tip of the iceberg here!
