Very handy device, I am really satisfied

I tried the sharpener, a good tool.
I'm satisfied.

Well packed package, came quickly (2.X ordered, 14.X picked up at the point). The design is easy to install. The table mount does its job, I'd sooner move the table than the sharpener, but it has a drawback: I had to use a washer due to a defect in the thread of the screw in the middle of its length. Diamonds shape the cutting edge of the knife well and sharpen them quickly. It's nice that the set includes leather and a bar of polishing paste. The photo shows the enlargement of the edges after sharpening with 240->800->2000->leather with polishing paste.
