Sharpening story - pesky knife to sharpen

[Jan]

Mr. Grepper, in my understanding your interesting observation could be explained by the fact that Cubitron II ceramic grains are precisely shaped to triangular forms. Even more the grain structure is micro replicated. Cubitron II cuts the steel surface and in some tougher steels it can generate long chips. Steel chipping is difficult to fix, such a steel is not suitable for knife blades. The harder the steel the less tough it usually is.
