Diamond Sharpening Stone Set,Diamond Lapping Plate Coarse/Medium/Fine Grit Sharpener, Honing Whetstone for Kitchen, Sharpening Dull (240+400+600+800+1000+1500)

I have used these diamond plates to sharpen half a dozen wood chisels so far, and am very pleased with the results. As other reviewers have suggested, I did a “break-in” procedure by using a large chisel, in my case, on all of the plates to remove any larger and looser pieces of grit, and used water to help float away the metal grit. Tools and plates were then wiped dry. I don’t remember if instructions came with the set, but I know that I can’t find any instructions now. The plates are well marked as to the grit size, appear to be well made, have a non-slip backing, and seem to cut effectively.The sharpening plates were used in combination with the GOINGMAKE sharpening guide set, also ordered through Amazon. I am quite pleased with both.The plates are somewhat small, so I would place a second plate behind the plate being used, to allow the roller of the sharpening guide to move a couple of inches further on each stroke. I sharpen with the sharp edge of the chisel pointed to the left, so for me, I put the second “overrun” diamond plate to the right of the first plate. I always kept the chisel point on the first plate, moving it back and forth pretty much the whole length of the plate, and allowed only the sharpening guide’s wheels to roll over part of the second plate. I found that setting the second plate perpendicular to the first in a T shape helped with stability.Despite the non-slip backing on the diamond plates, the plates wanted to move around on my bench. I clamped pieces of wood to the bench top to keep the plates from sliding, just snug enough that I could easily replace the plates as I rotated through the various grits.

I use these to sharpen my lathe wood turning scrapers. They are durable and make quick work of sharpening the chisels. If I didn't already have knife sharpening stones, I would probably use these as they are very convenient. I recommend using wet stone liquid as you would with any sharpening card.

These work quite well but are a trifle thin. Would have been 4 stars if thicker. Length and width are ideal.

Great piece, great price, great quality, want to buy more

I bought these for sharpening chisels and plane irons. I am very pleased with the results.

They are okay. Slow for the reputation diamond stones have.I used these to flatten waterstones and flatten a bar of hss. It wasn't long until the cutting speed degraded a lot. They aren't getting any worse now, not worn out, but settled slower than some of my other diamond tools. I don't know the reason for why that is. Maybe there is a build quality difference. If I was to say grit numbers based on handling my collection of waterstones for reference. 460 1300 1500 is about where they settled in.I have found these work better dry. Some of my better waterstones cut faster and the cheap stones don't. So, I think these are better than the bargain waterstones but not as good as quality waterstones once they have settled in. That said, after all of the use I put them through cutting very hard material, I was still able to re profile three chisles and sharpen them in a couple hours. It took me half a day to re profile one chisle on a cheap waterstone. Lot of metal to remove to get the angle I want for the purpose I want.Because these are thin, I use glass with double sided tape to keep them from bending. There isn't a lot of room for my hands doing it that way. If I get more diamond stones, I want to have the bar type next time.

Work great to sharpen my knifes.

Works well, but if you're looking to make a sharpening board with all three plates mounted side by side be aware that the foam backer is going to be a problem for that.
