Another concern that some knifemakers have is quenching too rapidly, worried it will lead to microscopic quench cracks or other bogeyman. And while I would be cautious when quenching anything in water, every steel that we have heat treated with Parks 50 has resulted in excellent toughness regardl...
Im basically following any guide you can find for beginner knife makers and using the very same steels and methods. I bought a piece of 1075 to try and see if the problem lies with my HT or those mystery steels. If thats not the case, can the problem actually lie in my bevel and ed...
if you don’t want to risk ruining your initial heat treatment with the torch, you can do this step in just about any home oven. Just make sure to clean all the oil off beforehand
Brad atPeters’ Heat Treatingtested a series of coupons using their vacuum furnaces. Larger heat treating operations used by knife companies and some knifemakers, generally use vacuum furnaces. And the heat treatment response is somewhat different than with plate quenching or oil quenching in a home...

the tempering treatment also partially stabilizes austenite for the reasons described above. There is a tension between the goals of transforming the maximum amount of retained austenite while also avoiding cracking. There are reports from some knifemakers that they have never had a crack with liquid...
Grange reported grain refinement through cycling above and below the austenite transformation temperature back in the 60’s [3, 8-9], and similar methods have become popular among knifemakers. This method has been given many names, including double austenitization, triple quenching, multiple quenchi...
has been found to have 6.5% carbide volume after heat treating [6] which is higher than the calculated values. The calculated values are usually directionally correct, however, and the carbide content difference between 13C26 and 14C28N appears to be confirmed in the micrographs, where there are...
for inexpensive consumer knives. The newer Nitro-V also is very similar to the original AEB-L showing that as a starting composition it is still a useful baseline. While it took quite some time for AEB-L to become a common knife steel among custom knifemakers, its use is now ubiquitous....
