Guys, I have been thinking about buying a very
hard, good quality asagi to finish my plane blades
and in the future perhaps a straight razor.

I have never seen an asagi or C12K, so I cannot
comment on their finess and hardness. My feeling
says that hardness is perhaps the same(on average)
and the best asagis are probably finer. The great
thing about the C12K is that it is probably 20 times
cheaper than very good asagi.

The really hard and fine stones tend to be very slow
and usually slightly scratchy. Solution is to use nagura
to create slurry. I saw this video of a ozuko asagi and
was wondering whether I could do the same with the C12k:

The stone in the video looks and sounds like a very hard stone.
I don't know if the chinese stone is that hard. That stone is
I am guessing 600+USD, so you know why I am hoping the C12K
could perform the same.

Thanks.
