Heat treating furnaces for knives are often calibrated at relatively high temperatures to ensure good austenitization. Sometimes the temperature may be somewhat off at low temperatures used for tempering. I used a thermocouple and an oven thermometer to compare the temperature between 300 and 550°F...
Pop’s Knife Supplycontacted me about doing a set of experiments on their 8670 steel. We talked about different heat treating variables we might test andJoey Berryof Pop’s heat treated and ground the coupons. I measured the hardness and toughness of each condition and I am providing the ana...
Step 8: Heattreating 2 More Images Before even thinking of heat treating, be sure you are happy with the shape of your blade, placement of the holes and your main grind. Be sure you cleaned up the deep scratches on the handle of your blade and in your edge. Having a clean blade befo...
Heat treating with the forge is something for the more experienced maker...but I dont recommend it. It is not accurate! Even after 30 years of forging and knifemaking I never would heat treat without a kiln or oven and a proper thermometer...heat treating is with edge geometry the most ...
When I first saw your pizza oven, I thought to myself, "This would make a great forge!" Apparently I was right. Awesome knife, sadly I do not have the skill, patience, or means to make one as nice as yours! Keep up the great work! 2 replies Phil Reilly(author)11 years ago Flag...
Im using old files and leaf springs mostly and I HT with a magnet, wait a couple dozen seconds past magnetic and quench in regular cooking oil. No problems with warps or cracks whatsoever, nor getting the steel hard. I temper to straw in the forge or in a kitchen oven. ...

you can do this step in just about any home oven. Just make sure to clean all the oil off beforehand or you will wind up smoking out the entire house and, if you’re married, have a significant other, a mom, a roommate, or anyone else who lives with you, you may very well wind...
For each of the corrosion resistance experiments that I performed I started with ~1/8″ starting stock and cut out 1 x 1.5 inch pieces. Each was wrapped in heat treating foil and austenitized in my Evenheat furnace for 15-30 minutes depending on the steel. The pieces were quenched betwee...
does not have to be heat treated to 65 Rc, but has the potential for certain knives, and heat treating to hardness levels such as 62-64 Rc is relatively easy since the steel has some headroom. And even if the target is only 60-61 Rc it has excellent corrosion resistance to go with ...
