Quench warping

I think everyone knows the phenomenon. I wrote a short rant about it:

Now I'm curious: is it a daily issue for everyone? How much warpage is too much?

Never had the issue, although I usually work with small blades. I experiment a large amount with hamons with 1084 through the usual w2 quenching in peanut oil and brine. I have however noticed quite a bit of sori quenching in water with some of my larger forged w2 pieces. But that's expected.

That's a nice article. I used a pro HT option for my first couple of years while I was still trying to get my bearing. Now I do a lot of my own but outside of axes I find the consistency was so much better when I used the HT. I don't really kick out enough quantity to make this a part of my process otherwise I would most certainly use a pro HT company.

I'm still experimenting with this, but my method is to stock 10 or so blades from the same material, ready for HT. Then send them to the pr HT company. They charge for it by the kilogram, BTW
