I would like to bow to the experience of someone who has done this with consistent results. I have had an order for tactical axes and I need to make this order without mistakes. I have been reading an old post from 8 years ago discussing what was the best thoughts, but no one did a summary. Here is that 101 posting: https://www.americanbladesmith.org/community/heat-treating-101/80crv2/

I am concerned as I also saw a newer post with a man out of south Dakota having difficulties, and I am guessing he read the original post and it didn't work for him. If anyone has experience, don't hesitate to tell me every detail you are willing to share including your quenchant oil, oil temp, steel prep, etc.
