Spring Steel Heating Color Guide For Knife Making

This will be a short but important post. Above is a piece of heated spring steel showing the color needed to do different things.  Sometimes having a true to life visual reference is the best way to get a feel for a certain technique or process. I hope this helps all the people just now jumping into the world of knife-making.  The red color in my experience gets the most hardening but you can also quench at orange with good results.
