How sharp is the knife sharpened by CATRA?
I exchanged a few emails with a mobile sharpener in Cyprus, he uses CATRA I 100 for many years
His name is Dave, website and photo:

This does not answer your question, since Dave hasn't got a BESS sharpness tester, but he says that CATRA I 100 is reliable.
CATRA have done a comparative testing of sharpness on their tester:
"Extensive sharpness testing on the ISO 8442.5 tester reveals that levels of sharpness produced on the CATRA model I 100 are the highest consistently produced by any system. The edge life for given knife blade steel are also amongst the best achieved for re-sharpenable commercial use knives."

As a hue to our ongoing discussion on coarse vs fine edges, interesting is CATRA's reference to the grinding wheel grit by intended use:
Very smooth - Fish and meat filleting
Smooth - General fish and meat processing
Medium - Vegetable and general kitchen use
Coarse - nonfood industrial use

If we had printed the PT50 Series operators manual in the Czech language he'd be taking BESS measurements by now. If we don't provide him with a Czech translation he'll likely have to wait until he's 4 before he can interpret our English version.

Mike, do not worry, our small Dan has already begun to learn English. His first word is “sorry”.
