...for A2, ATS-34, CPM S30V. Can anyone recommend a very high quality facility who'll do only one or two blades at a time? Thanks!
 
I use Texas Knifemaker's Supply for A-2 and D-2. I've been very happy with the results. The price is good too.
 
Welcome to Blade Forums, Erik! Perhaps, if you fill in your profile with location, some people here might be able to suggest a more regional heat treat service. More than one maker here uses local services that not everyone will be aware of. :)
 
Will enter profile info. I'm familiar with Texas Knifemakers... nice folks. Hadn't even considered them til you brought it up. I think they cryo treat A2. Will check my catalog or call. Thanks!
 
If I remember right, Texas Knifemakers heat treats to 57 HRC only. If you are going to pay for and use a high alloy tool steel like A2 or D2 that has an optimum hardness, you want to be able to get your desired hardness. A2 peaks in impact toughness at 60-61 HRC. At 57 you will get edge rolling under stress.

I have bent thin A2 blades hardened to 60 up to 90° and had them spring back without damage (I was trying to straighten them up after warping in an oil quench).
 
Personally, Erik, despite the high cost on one or two blades, I'd still go with Paul Bos. Others opinions will vary. There are others from FL here, so they may be able to offer you a local alternative.

Thanks for filling in the info. Again, welcome!

Paul Bos does heat treat single blades...just more expensive that way, and IMHO worth every penny.

Steve, if you check them immediately after quench, before they cool too much, you can straighten them.

I plate quench these days and have not had a warped blades since. Large thin blades like chefs and butcher knives are the only things I had trouble with, anyway.

I really like A2 in 1/16" thickness for kitchen slicers. Harden that up to 60 or so and you have the kitchen knife from hell.
