Okay we lost a few days last week do to some really cold days. But we got the two knives into heat treat today. From here its al about cleaning up the grinds, and getting ready to select the handle material.
The knives went into the oven for a "Normalizing" cycle which helps refine the grain structure of the steel.
First cycle of normalizing
Once the normalizing cycle is done and the knives have completely cooled, they go back in the oven and heat up to 1500 degrees for approximately 7-8 minutes. One at a time they are removed very quickly and placed into a very good quench oil called Parks 50
Press setup for getting them flat and straight
Tomorrow they will go through a temper cycle to get them at the proper hardness which will be between 58-59 Rockwell "C" scale. Then we get going on finishing them!
Thanks and stay tuned for the next installment.
