Fixin to sharpen a new blade and do some cutting. Question: If I dont like the way the blade cuts can I aneall the blade and start over or must I build another blade Id like to settle the tempering formula out before I build a new blade. Ive been tempering at 400 but have moved to 387 this time.

You can re-harden the blade as many times as you wish. As long as you do not overheat the blade you will not hurt it one bit. You may have to sharpen some of the decarb off of the edge. If it does not cut the first time, simply sharpen it again and give it another chance.

Remember to edge flex the blade before you try cut.

I love to hear about testing! Good Luck!

I'd say it depends on how much mass the blade has.

By the time I've gotten a knife finished with the right geometry for slicing, it's pretty easy to over heat the edge.

If the blade is wide enough, you have room to grind it back and try again.

If you don't etch the blade, you won't know if it's been overheated.

It's kind of a catch 22. On one hand, you have a knife that you've finished and know. Is it easier to just make another blade, or risk toasting the blade you have?

You'll figure it out for yourself I reckon.
