Busse Zero Tolerance Question

[JFLemm]

I have been looking through the forum for an answer to a question that I have. I have several Busse Zero Tolerance knives, about half are polished finish with the logo and "Zero Tolerance" engraved on the reverse side and half are coated and sterile. Is there any significance to the differences in the blades?

Thanks in advance.

Yep. Some are coated.
AFAIK, the measurements should be the same (exceptions might be customs & I have a ztbm from a 2009 Travelling Trough show with a 9in blade), the coated will be slightly thicker of course- that coating adding that little bit more.
