Hello kkf I'm doing a few knives to keep me occupied these days, the two of them is iron clad white Hitachi, I wondered if water quenching would be a good idea for them, as the specification started that the window for a good quench is much more forgiving with water. I'm attaching an image of the chart and of it fails I'll do it after. The knives are two fairly simple knives, a 200mm Western profile carver, and a small pairing less then 100mm so I'm hoping they would be less risk free then more "advanced/bigger" knives. My experience is two oil quenches in o2 i am quite happy with how the edges hold up in use, no issues with warping out cracking. I'm heating in a brick forge, I control the temperature of the oil with an infrared temperature gun, and heat the oil with the heater from my deep fryer, then pull it out when I'm around 70 c. I have nothing but a magnet, and my eyes to judge the temperature on the steel. Would you still strongly discourage using water or what do you think?
