Jackyl, In all honesty I enjoy mokeme on some of the fancier stuff I collect. In addition to others mentioned and not mentioned, Hugh Bartug, Mel Pardue, Devin Thomas and many others forge it.
I would not want it on any of my working/heavy use knives it is very soft. (I can attest from the jerk that slammed the pictured one in the Pardue post down on a table one time. The other side of the knife has a nice dent in the mokeme.)
Most of my comments in the Mel Pardue thread as far as mokeme and jigged bone were meant as humor and as you can see Les responded in kind. (I would be willing to bet my entire collection he was not arrested for murder in Canada!), but his point is quite valid.
Although I have seen jigged bone that in my opinion looks beautiful, the source is still the shin of bovines (not exactly an exotic or rare or state of the art material that can take a lot of use and some abuse without cracking).
Mokeme is so soft a healthy fingernail and a good bit of pressure can damage it. I am not sure of the RC. In my opinion, it can be beautiful and I own and will continue to own some work that incorporates its use, but it is darn soft. As a rule, they are pretty much "wall hangers" in my collection rather than a "user" or even one I would carry around without a nice plush case to keep it protected. I think that the softness might be what Les is referring to when he jokes that Mokeme is Japanese for "should not be on a knife".
It might be a small improvement on using lead as a handle material for a knife that is intended for anything above very light use.
A friend on TKCL found this site a while back. It should cover some of the more technical aspects of Mokeme. (Thanks Aaron!)The technical article was written by one of the guys that owns a site in one of Para's links above.
Site for Mokeme information
As far as Don's site (again see Paracelsus' post for the link), it is in my top five as far as knives go and has been there from the beginning. (Knives aside, it also happens to be a well done site as far as presentation.) There is a wealth of information, inspiration and wisdom there. If you are a collector or maker, it would be well worth your time to check out the whole site.
