[Woodcarver] performing cryogenics (freezing at 300* below zero) onwood carving tools.

[Joe Dillett]

Hi Jim,

I checked this Cryogenics freezing for carving tools. The process greatly 
helps improve a metal's ability to hold an edge only if it has been air 
quenched in the heat treat process and not all the carbon atoms have (forgot 
the technical term) stablized. It does very little or no improvement to 
metals that have been quenched in oil or water during the heat-treat 
process. Our top quality carving tools have seen the oil or water quench so 
I'm lead to believe Cryogenics freezing will not improve there ability to 
hold an edge.

Sorry I forgot all the technical terms the fellow, who does the process, 
used when I questioned him for one of my Ask Joe features for Carving 
Magazine. But he felt it his process would not improve the quality of our 
tools so I answered the individual who asked the question and didn't write 
an article on it because he felt it didn't apply to us carvers.
