More on maintaining knives
From: | Gayle Callis <uvsgc@montana.edu> |
Hi Frances,
I have a Shandon Knife sharpener that does the job for me, and have used
Dorn and Hart to do my reconditioning for really damaged knives (inherited
a bunch of thes AND once reconditioned, I only have to sharpen. The edges
are maintained for years with the Shandon plus I can do all profile steel
knives, including D profile Tungsten carbide. The sharpener has paid for
itself many times over, a good investment for the perfect knife edge if you
need to use c profile steel knives, etc.
Hmmm good endorsement today!
