The 3 stars I give so as mean my experiences:
I have several knife back and going forth, until I got an acceptable.
Either clamp the blade, or it can not be properly set up, the Virobloc jammed or too loose, the handle has quirks and the blade is as good as dull - some of these obvious flaws in the manufacturing final inspection can accept others make the knife unusable or destroy the joy like new product.
However, I'm working like and have adjusted the grip on my knife and sharpened the blade, the blank was therefore worth the money, because I now have a usable knife according to my ideas.
