MAYBE! I kinda seriously doubt a pro shop would use one that much,
time is money and they are slower than a dry grinder.

I was thinking if it's a pro shop, they've be using a Tormek far more
often than any private user. If that's so, then the warranty even in
the face of repeated commercial use is a good recommendation for the
quality of the tool.

As to dry grinding, I'm of the impression that dry grinding is subject
to heat build up which can hurt the temper of the metal in a knife. I
hope (maybe naively), that a pro shop would be a little more
responsible with their customer's knives and not subject them to the
effects of heat deterioration.
