It's OK Jacob; I didn't expect you to learn anything from the information I posted.

Yeah sorry; I know "thinking for yourself" upsets people, especially our resident prima-donnas, who get quite tetchy! :lol: :lol:

See what I mean! :lol: :lol:

Actually I did learn something;

5. The wear at the tip does not result in as much blunting of the edge as might be expected from this loss of material because wear at the top and bottom of the blade lead to some self-sharpening of the blade (see Figure 2).

I thought that was interesting. I've often pointed out that a super sharp blade rapidly looses it's super edge and becomes merely "sharp". Hence super sharpening is somewhat impractical, and possibly pointless.
As we know from experience the "normal" level of sharpness lasts for some time, but I hadn't thought of it as "self sharpening" phenomenon.
In other words the rate of attrition falls off sharply, leaving a usable level of sharpness for some time.

I haven't tried homeopathy, cannibalism, line dancing and zoophilia. Have you?

I can strongly recommend line dancing...loads more fun than sharpening.
