Thread: Shoubudani type 100 problems

The first thing to try, considering what you do, and do not, have is to try the shoobie doobie without any slurry. Go from the 12k to the shoobie and see what that does for your edge. If your honing technique is good, it likely either will improve the edge or do nothing. It is possible that your nagura is degrading your 12k edge

Strop and shave after the Shobudani. You can use your HHT to make sure the edge is coming right off the 12k.

Ditto that.

Clear water, no lapping for a while. That should give a very good sense of the base stone. No spurious nagurious putting scratchy cutting particles on the stone.

A good shoubu stone should be similar in fineness to a good chinese phig, but it should have a wider range of cut speeds in various states of use.

What did you mean , as saying ''good '' . Arent they all selected and good . I asc as im very intrested

Too many finishers, 2 of which are of completely unknown grit, very few Natural stones are higher than 12k

And using slurry to finish is an art form in itself with a long learning curve…

As said, pick one and learn it…

There are shoubu stones all over the map in terms of particle size, color, size, softness/hardness, and in feel. Some of them have scratchy particles (but the same is often true of other mine stones, even the most desirable mines like nakayama, okudo, etc).

Japanese naturals vary stone to stone. i've had three shoubus and they were all a little different. (actually, one wasn't a razor stone but it looked nice. It had a terrible feel on clear water, and left some random scratches). I sold it to knife people who won't be as particular, and took a loss.
