jim on this last bunch of knives you cut caerdboard with did you polish the edges as you did the knives i had lent you? if so the members may sharpen to the same angle bevel as you do but unless they polish the edge the same as yourself they will not achive the same cutting quality. the bevel is repeatable but your mirror polish may be impossible for them to duplicate.knifenut 1013 & some other members can certainly do this polish but i ca'nt duplicate it myself.the edgepro system you use is no small investment.thanks dennis

All the knives were reprofiled to 15 degrees per side (30 Degree edge) and have polished edges to keep things equal in the tests and to provide maximum cutting efficiency and edge holding for each steel. :thumbup:

I do know what you mean about the Edge Pro, but in the interest of the tests I had to keep everything equal from when I started the series.

Even if i didn't polish the edges and just took them up to the 600 Grit Stone, even that equals a 5,000 Grit Japanese Water stone.

Jin,
Thanks for doing these tests! It's been one good source of the steel comparison info.
I'd appreciate, if you help me understanding your ranking a bit better. I can see how good the final paper cutting is going, but at the same time I see great difference in how good cardboard cutting is for different steels. For example, you ranked zdp-189 on top of M4, but if you replay your Mule M4 test you will no doubts see the superiority of M4 in cardboard cutting. I am wondering how you'd comment on how you weigh the cardboard part vs the final paper cutting. From my perspective, I favor a steel which would be superior in both jobs, as I see no reason for a steel to be the best in paper cutting and to be an inferior to another one in the carboard cutting..

It's about edge retention in the end. :thumbup:

If the blade won't cut paper at the end it won't shave either.
