Ultra Sharp Diamond Sharpening Stone Set - 8 x 3 Coarse/Medium/Extra Fine

I initially experienced some frustration trying to use these stones / plates. I was trying to sharpen a very cheap Harbor Freight plane iron to break in the plates and just couldn't get it to abrade on the coarse stone. As a last ditch effort, I sent an email to Best Sharpening Stones, the seller, and they got back to me the very same day. Even asked if I would send a phone number so they could call me. They also provided some details and information on sharpening that helped me out a ton. Really excellent customer service experience for me. I couldn't recommend them enough. Even if you're not going to buy these diamond plates, but some other sort of sharpening stone, I would definitely recommend you buy from this company.After I received a bit more instruction and a bit more information, the stones really started working much better. The issue was user error and knowledge based as opposed to product based. Mine were very flat and consistent out of the box. No issues with fit or finish there. Nice weight, decent little holder for the stones and they seem to work quite well. I'm no expert, but they're definitely a step up from the smaller composite DMT "stones" I had purchased before. I wish I'd just gone with these stones from Best Sharpening earlier. Live and learn.

I am new to any sharpening - I bought these for wood chisels so I can learn some basics with woodworking. After watching a lot of tutorials about sharpening chisels I settled on these as likely an adequate solution. Indeed they work well. I started by testing them out on an Irwin chisel that was in rough shape, had been dropped many times and used incorrectly (by me) many times. I was able to get it very straight and sharp. I have also used these to sharpen up a set of new Dewalt chisels as well as kitchen knives. I also bought the holder that goes with these and a leather strop paddle for finishing. The advantage of these stones is that they are a large size which makes working with them easy, also they are easy clean up with water. Keep them dry or they will rust. I would like to get a stone even more fine than the extra fine that comes with this set, but that will set me back quite a bit, and honestly, relative to my skills does not seem necessary at this point. I get by with these and a leather strop.

Good heavy duty plates. Cant say anything negative for the price. Pretty aggressive until broken in but now they sharpen very well .

These work extremely well and definitely very quickly. I have tried several different stones for sharpening and even have a very nice Tormek machine that is good for many applications. I bought these specifically for sharpening plane irons after watching a video on sharpening by Paul Sellers. I had never sharpened free hand before, and I was a bit nervous about trying it, so I experimented with a cheaper iron I figured I wouldn't use much anyway. After a little practice (very little) I am getting much better with it and I am having excellent results with that cheap iron. So much so that I haven't sharpened the Hock Tools iron I intended to use in its place. I'll wait for that until I am much more proficient at free hand.The holder exceeded my expectations by a mile. I was hoping to buy this set without it in order to save some money, but it is fantastic. It holds the plates securely and "sticks" to the surface you set it on to do your sharpening. It doesn't move or shift one little bit at all.All I can say about the seller is that I had absolutely no problems whatsoever. My purchase was processed and delivered quickly and without a hitch.I recommend this set without reservation. 100% completely satisfied.

Nice product overall, especially considering the price. The two finer ones were dead-flat when checked on my surface plate. The coarse one was convex, begin low by .015 on one end and .018 on the other. Nice, thick steel (1/4 inch) and the supplied holder is effective. Also the heavy cardboard envelopes will be nice for storage. Very sharp as delivered. Time will tell how they hold up but with fairly light hobby use they should last a long time.

Recommended for anyone wanting to get into sharpening with diamond stones and wants something with quality. Sharpening with these are an ease and puts a great edge quite quickly. The steel block that they're attached to does have some heft to it, so these are quite bulky stones. Regardless, they are great stones, definitely recommended. Some lapping/honing fluid to go with these are also strongly suggested as well.

they work great! this is the first set of diamond "stones" i have bought and used. they start out pretty aggressive as stated by the maker and they wear in nicely after a few uses. i use water for lube and to clear the swarth. the thing that you have to be careful about is that if you use too much pressure the diamonds will slip. i have a couple streaks on the 1200 stone, they don't affect the performance but you can see them plain as day. it is a little hard to keep your discipline especially if you are flattening chisel backs or restoring old plane irons but just remember that more pressure will not speed up the cutting, it will only damage the surface. the 1200 stone is good enough for chisels if you strop it afterward. then every 10-15 minutes of use i will give it a few strokes on the strop and that usually keeps the chisels sharp. if you actually start noticing its not cutting as well then you just touch it up on the 1200 stone and then strop and you are good to go! for plane irons i usually follow up with an 8000 grit whetstone and then strop but you don't need to do this. i just like my plane irons extra sharp
