I have heard that it is a very durable coating. That is one reason that I tend to say away from Black T coated blades because they wear off. I think more people would purchase coated blades if they held up.
Any chance that they will come out with more Sifu's with out finger groves again???
Or, different colored handles, I love my red handle but would really like a blue g-10 or even a Titanium handle would be cool.
