I've recently gotten the itch to try my hand at a couple of folders. Had a few questions about making the springs. Is it possible to spring temper a portion of a piece of steel? For example, liner locks, do makers generally heat the entire liner to a spring temper or just the portion that needs it? What happens to the area between the spring tempered portion and the rest of the steel? Does the steel just conduct the heat evenly enough to smoothly blend the two, or does it create an area of weakness/weirdness? Is it possible to get satisfactory results doing this by eye (color), or is there another practical method? Is there a steel that is considered a clear choice for this type of application? I know I've seen a lot of stainless liners (302?) and a lot of titanium (not going to happen). I don't see many posts related to folders here in shop talk, but I'm sure someone here can shed some light. Please excuse me if this is covered in one of the stickies. Most of the links in the newbie info sticky are dead, and my troglodyte brain has a hard time diciphering anything Mr. Cashen writes.
