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

[Jeodea at aol.com]

A company in Omaha, NE is offering a service to perform   cryogenics 
(freezing at 300* below zero) on carving tools.  
 
Has anyone tried this? Is there any  metallurgists out there that could 
comment on the effect on our  tools?
 
I lived in Omaha for 4 years and well  remember 4 weeks of -27 below zero 
weather - that didn't help my carving tools  any!!
