Here is I think quantifiably and undeniably the final word on “Razor Sharp” 🙂

Cliff: I watched the rant video on razor sharpness by Skallagrim. As it wrapped up, I saw this one posted alongside. The weirdest knife mechanism ever. I agree.

<iframe src=”https://www.youtube.com/embed/TtBliK5ugDI?feature=oembed” width=”670″ height=”377″ frameborder=”0″ allowfullscreen=”allowfullscreen”></iframe> Most of us understand it is difficult to sharpen free hand and fortunate for us to have systems such as WE for a quick aid. Free hand skill takes time to develop – with proper tutelage, as witness, even today with the rare Togishi trade in Japan.
This thread is interesting to say the least, which brings me back to the Samurai days in old Japan. I found it interesting after Bladesmith’s work was done, he hand the blade to a Togishi to bring out true life for his blade. After Togishi’s work was done, to verify sharpness, it was used in one skilled stroke and rated as a one, two or three man blade! The higher the number of man, the more value….not in a good position to be any kind of prisoner in those days, where it was the source for human specimen.
Ancient high valued, gleaming free hand mirror’ed blades through the combined efforts by Master Bladesmith & Togishi exits today. Seeing one in person gives me chicken skin!

One of the tests I had originally posted challenged me to try it for myself. I found it to be a teenie tiny bit harder then I thought.
Perhaps the steeper taper on the primary bevels of a pocket knife make it harder then on a nice thin kitchen knife, but it is possible.All in all I found it to be, if nothing else, a fun test for sharpness. My paper testing progression has over time went from something like:
Slicing copy paper
Push cutting copy paper
Slicing phone book
Push cutting phone book
Push cutting vertical free standing phone book.The last test was not easy and it got me thinking of how a simple test can indeed equate to a certain level of edge refinement, sharpness, or keenness.
Note: Full disclosure this was done on my 1×30 with belts.

Hello everyone ! Its been three weeks since I’ve been here. Just checking in to see what new. I’ve learned a ton about my own personal knife sharpening over that time. Its been fun, and eye opening.. I find that my go too knives are very practical, accurate, and enjoyable to use. The WE has made a very big and positive difference in my personal kitchen experiences. I am now very spoiled by a sharp knife, and can tell from one day to the next, the level of sharpness, and when the need for a touch up is necessary. I can tell the difference between good quality steel, and a knife that does not hold an edge very well but can be sharpened to an edge of hair splitting sharpness.
I could never have this much fun without the WE making my tools as go9od as they can be.
Hope all is well with everyone
