How did all this happen?


My life is full of guns, dogs and engineering. I own and run a small business, selling and servicing electric motors.
Sharp knives and guns have always been a passion.

There is too much myth with how sharpness is achieved. It is only...

  1. Engineering
  2. Geometry
  3. The quality of the stone
  4. The quality of the blade material

We have a demonstrational unit set up permanently, anyone is welcome to bring in their own knives and try out the system for themselves.
