Home Forums Gear Knives and Blades DIY Knife Tutorial

A quick update, these pictures are from the heat treating process. With simple high carbon steels you need to heat the blade until the critical point when it is no longer magnetic. Then we quench in canola oil heated to 130 degrees Fahrenheit.





I test the edge with a file, the file will scate off like glass and not dig in or start to cut..... Success.





Now it's time to temper the blade with two one hour cycles at 400 degrees Fahrenheit. Let the blade come to room temperature between the cycles. This should produce a knife around 59RC with this steel.

Note to self, don't bend over and pick something up near the forge while heat treating.... I'll call this frosted look Porcupine!
