3 PCS Diamond Sharpening Stone Diamond Knife Sharpener Plate Honing Whetstone for Knives Chisel (240#+600#+1200#)

They seemed to work great. Although sharpening my hand planes with water discolored the plates. Making the grit marking on them harder to see. The rubber like backings didn’t grip my counter or table. They need to be held in place so I could use both hands for sharpening control. Notice the last photo how you can hardly read the numbers on them anymore. But the did sharpen my blades quite well for a price you can’t beat.

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.

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

I like them. The 3000 grit makes my quality pocket knife shave the hair on my arm which satisfies me.

Great quality stones for the price. I would suggest getting the course or stones that are also containing the finer stones up to 3000 grit. But overall no complaints.

They’re ok, but it’s likely cheaper in the long run to buy proper chisel and plane sharpening stones, or even to use sandpaper adhered to a flat surface.TLDR: rusts right away. Losing grit as of the date of this review.

Perfect range of grits, big enough to do an axe or machete, small enough to carry in a backpack. Best quality I've found so far, good for price

Not even close to flat. I've had good luck with other brands in this price range so surprised to find this one so badly warped. Make sure you check before you sharpen because the stone I got would do a number on expensive chisels and plane irons.
