Thanks Tom and Mark... great input! Tom, is that why you cleaned off your slurry AND swarf before the final step with the 10k choseras in the recent video of you shaving w/ the pocket knife? I know you explained it in the video... this minimalizes the cutting action and polishes more (if I remember correctly)... am I right?

Josh,

I just noticed the link to the book page from Google Books I posted before was not working. So here is a retry: The Perfect Edge: The Ultimate Guide to Sharpening for Woodworkers. The folder on the Nagura stone contains some information regarding your question.

Obviously I'm not the expert here. Just pointing to some interesting material.

Tom, have you got a clue why stones that require water seem to wear faster? (Or is it a wrong observation?) My el cheapo stones that require almost constant soaking/keeping wet wear down very fast, whereas the Wicked Edge ceramic stones don't seem to abrade at all. Does the water cause the wearing down (e.g., due to dissolving the resin bond), or is the wearing down the reason you want to add water (to create the slurry and remove the swarf)? Or do we need Ken to answer this question?

Ken, where are you? Come back! ;) (You have got an unread PM, by the way. The notification is rather obfuscated, but you can access it by clicking on the link in the top right corner.)

I'd say it is a correct generalization when you throw in the sheer number of "el cheapo" stones on the market :P

But Shaptons and Choseras are in a class of their own on the high end, and are designed to hold up longer while cutting faster, so I think you'd be wrong in this specific case. ;)

Overall, I think wear rates are more dependent on the binding agent/matrix hardness. Ceramic stones like the WEPS ceramic and the Shaptons use a ceramic binder which holds the abrasives in place better and longer. Choseras use a Magnesia bond, which is a little softer and more "cushy" (hence the wonderful feedback).

In theory, by using water the wear rate is increased overall because the abrasion rate is increased as you are flushing the system of swarf, which is in contrast to stones used dry, which "loads up" the surface, slowing abrasion, thus slowing the wear rate down.

Hey Tom, the picture is getting clearer and clearer!



What occurs to me is that the WEPS ceramic stones and the Shapton stones seem very similar. Both use aluminium oxide with a ceramic bond, both are hardly porous and very slow wearing.

Are there any major differences between them? Why is it that the Shaptons require some water (but only a little bit) and the WEPS ceramics stones don’t (although a little bit of water might help)?

And now I am going to use my Chosera stones for the first time :mrgreen: .

I feel the WEPS ceramics have a softer matrix than the Shaptons, overall. This makes sense because you want the ceramic to be able to come loose on the WEPS ceramics, but the Shapton mentality is to keep on abrading at every level.

In other news, I will be making some lapping videos with my WEPS Shaptons and Choseras this weekend. Keep an eye on my Youtube channel! B)
