This video is made in the workshop of Bulgarian knife maker Stoil Manchev - well known here in Bulgaria like "Silverman".

During the two days project I spent more than 10 hours with the knife maker and I filmed parts of his work on this beautiful knife - "Model 1" in Carbon Fiber and M390 Steel.

The knife is special Carbon Fiber edition to the basic "Model 1" in M390 or K110 steel with green micarta.

The hollow grind was made on a 20 inch wheel - during the video you will see the thickness of the blade behind the cutting edge.

The abrasive belts for grinding and finishing the blade are:
