DMTD3EFC 3-inch Dia-Sharp Sharpener, Credit Card Sized- Extra-Fine, Fine and Coarse Diamond -Set of 3

These have been brilliant. I bought them to bring some rather tired kitchen knives back to life, and going through all three has got them so sharp that my girlfriend is nervous of using them! The coarse one even let me remove some quite deep nicks in the blade, so it does remove quite a lot of material.The only thing missing from the kit is something to "stick" the plates down as you use them. I ended up cutting out a section of one of those dashboard mats that hold your phone in place, and it works perfectly.

Great product to keep nearby when woodworking, can be used to quick sharpen wood chisels or turning chisels.I have bought the fine grade before to use it for my turning chisels and after using it i came back and ordered the full set.

These are really handy. I use to sharpen my wood turning chisels. I don’t always need to use my grinder so having these in my back pocket is a bonus. They are not cheap but hopefully they will last a long time. I have coarse, fine and extra fine for just honing my chisels in between projects.

I find these DMT sharpening cards ideal for a quick honing during a turning project. A couple of quick wipes over a wood turning tool bevel and the tool is ready to continue giving a clean cut.

Good kit with the right grits for all types of sharpening. Quality feel & weight and leaves a good edge for woodturning chisels, knives and router bits.

Very good mini hones, I use mine for sharpening my router bits etc. Some of my diamond coating did come off on the first sharpening so i have a little bold spot at the front. Bought some DMT double sided stones too which are much better quality. DMT really must improve there customer service, i have emailed them a number of times regarding my faulty hone and have got no response.

My father has the trend card with 2 grits on 1 card and after using I needed to buy my own for sharpening drill and router bits. The 3 cards arrived in great condition and i'm happy with them.

I love these. Even though I have equipment for sharpening these keep the cutting edge very close to what's needed. A must for any tool kit.Thanks
