The machine comes with a 2 clamp system.

Useful extensions, all available in the store, are:

Set CBN stones from 100-1200 grit

Set boride stones

CBN 80 as a workhorse (eats the steel)

1 set of Belgian chunks for polishing the cutting edge

For long and/or flexible knives, the extension to 4 clamps is recommended (40cm)

It was very important to me to combine the best of different systems in one machine.

I think I have succeeded in doing this well.

Of course, everything has been there before but never combined in one machine.

This machine can do many things that I normally need different systems for.

All future extensions will be based on this base model and will be compatible.

So in the end you have a grinding system that meets almost all requirements
