In another thred, RH Clark recommended Red DMT for sharpening a knife.

Is this a diamond whet stone ?

Not sure I'm understanding this right, but would like to purchase a "better" stone, than the Japanese water stones I've been using for years.

The water stone wears off quickly and has to be replaced frequently, although it does work well, with a steel to finish.

I sharpen by hand, and want the BEST "stone" I can get.

Diamonds sound like the best alternative.... Maybe ?
