Thread: DMTs up to 8K

For me, slurry dulling is a myth unless you plan to shave off your bevel setter..

Slurry dulling is something I never experienced.

I have the full set of DMTs and a handful of diamond loaded strops. I have learned (through many trials) that diamonds work very fast and the resulting edges are very sharp, but have a harshness that I cannot tame without going back to 4k water stones.

Faces vary. Mine does not like diamonds.

I'm still trying to wrap my head around this notion of slurry banging into the edge. I'm just not able to envision a particle that size floating in a slurry holding enough inertia to damage an edge.

OTOH swarf is present on DMTs unless you rinse and scrub after every stroke. I'd suggest this would be more detrimental to an edge than a properly evolved slurry...but I'm just supposing.

Love my diamonds for my competition and hard use knives, but I like water stones for my razors.

Regarding the slurry dulling, I am only repeating what I have read here. Ive never used a coti but some new users report their blades getting duller after the bevel set. And the reason given was the garnets are suspended in the slurry and dulling the edge. Ive worked up slurry on my 4k Norton with my dmt and didn't find any apparent difference. It did cut a little faster. Regarding dmts, I find them very useful, I use very little pressure and soapy water. I get the same hht after the dmt 8k as I get with the Norton 8k. Everybody is different so we will do what gets us to where we want to be. I have shaved off a coti edge and it felt dullish. The phig is very slow. I know naturals vary as do the people that use them. I would love to get a j nat, but where do you start? And all the nagura stones. I wouldn't know a good one from a bad one. Unless you buy 10 and try them out. Eschers, thuringians, are highly variable from what I have read also. Actually eschers are thuringians . So I guess Im stuck with my dmts, nortons and film! But one of these days Im gonna have to scratch the itch of j nats.
