Which is the "best" finish grit using diamond plates @ 15 DPS for general purpose use?
400 or 1000?

Is it true that CPM154 should not be taken to a more acute 10DPS?

If it matters, the blade in question is the Sheeepsfoot on the 2018 Buck 301 Form Knife.

Thank you in adance.
 
I get really good results using 600 grit to finish my Buck 301 forum knife at about 13 dps. I shoot for 25-26 degrees inclusive. That seems to be the sweet spot for Bucks cpm154.
 
With diamond on smaller traditional pocketknife blades like the Buck 301's, I rarely go below ~ 600 or so (like DMT's Fine). A very coarse edge on a small blade tends to limit its usefulness for the typically finer cutting jobs I usually do with such small blades. A shorter cutting edge length is better suited to push-cutting tasks, as far as I'm concerned. So, a finer finish works better there. By the time I fine-tune these smaller blades' edges to my liking, they trend more toward the EF end (1200 diamond or finer) of the finishing scale. A little short of polished, and still retaining some micro-toothy bite.

I do like an aggressively coarse edge on a bigger blade though, such as a Buck 110, etc. - even using an XC (220) diamond to set the bevels and apex the edge, then following with a 'barely-there' microbevel applied using a very fine hone, like a fine ceramic or maybe a 1200 diamond. A combination like that can create an aggressive, slicing cutter for bigger jobs, taking advantage of the cutting edge's extra length.

No idea. The plates that came with my EZ WARES guided rod with 10/15/20/25/30 degree slots are only marked "400" and "1000".

Without knowing more, I would say going to 1000 with those diamond plates should be fine. I believe the system you are working off of is made in Malaysia so hard to tell if it is ANSI or JIS. In my experience, 400 grit diamond is usually pretty rough. Lowest I will go as a "last stone" with diamonds would be around 600 or 800. After setting the edge with the 400 I would probably use the 1000 to finish and remove the burr. Should still get some aggressive slicing out of that edge with very light stropping after the fact.

Or Singapore.
I think he said he is in Singapore, when I contacted him about a replacement 400/1000 grit plate/file. (which he did send. I wore out the original reprofiling/thinning the edge of a "few" knives to 10 DPS.)

Still could be either ANSI or JIS from that neck of the woods.
