How would one quench a double-edge knife? I gather that edge quenching is out of the question. Also I do my stuff in my backyard, so no torch all tribal. :) Also I need to know if tempering to 400F for 1095 would work. i guess I would carefully temper both edges or use the oven at 400? Any ideas are very welcome. Thanks
 
Definately quench point down and I'm sure you know to move the blade edge to edge - not side to side - to maximize contact with cooler oil. As to the temper temp for 1095 - I can't say for sure because I've never used it but 400 does not sound out of line. Get a separate oven thermometer to ensure the temp in your kitchen oven, and temper the entire blade. Welcome, Good Luck and let us see what you come up with!

Edited to add, my vertical quench tank is just an old paper milk carton. Others use all kinds of better stuff like pvc tubing etc... :o You'll get good recommendations from some others I'm sure.
 
Quench point down in fast oil.Temper in the oven at 400F for two hours.Temper twice.Forget trying to clay coat double edge blades.You can do it but it is complicated.
I know Dave uses a milk carton,but something made of metal that holds at least a gallon of oil might work a bit better and safer.

I clay coated a couple daggers. used fireplace high temp caulk that comes in a tube. Take a compass with a pencil and mark an even line all the way around the blade depending on blade width how far in you want to harden. then put masking tape from the cutting edge to the pencil mark. Apply a good heavy coat 1/8" - 3/16" of the cement over the blade, while still wet pull the tape slowly and it will leave the cutting edge evenly exposed all the way around. set it a side for a few days to let it dry. Bring it up to heat checking the exposed edge regularly, as soon as the edge is up to non magnetic quench point down.The cement will help keep the heat from getting to the center portions and also keep it from cooling to quickly. Cement will usually fall off as the blade cools.

Good luck,

Bill

:D You're right Stacy, and I'm keeping my eyes peeled for something reasonably safe and reusable. I don't recommend the milk carton, only mention it as my own field expedient. Mortar tubes and stuff like that serve others very well and are far superior!
