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. Review: Good kit with the right grits for all types of sharpening - 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. ## Features - Three different diamond stones: Extra fine for polishing and smoothing a cutting edge, fine for grinding a razor-sharp edge - and coarse for grinding a rounded blade - Faster than conventional stones thanks to the micronised monocrystalline diamond surface - No oil required, dry or with water, solid construction for years of performance and re service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00006IIO3 | | Best Sellers Rank | 25,830 in Garden ( See Top 100 in Garden ) 16 in Axe & Knife Sharpeners | | Brand | DMT | | Brand Name | DMT | | Colour | Diamond | | Country Of Origin | USA | | Customer Reviews | 4.5 out of 5 stars 1,218 Reviews | | Global Trade Identification Number | 00017042007546 | | Grit Type | Extra Fine, Fine, Coarse | | Grit type | Extra Fine, Fine, Coarse | | Included Components | 1 x 3-inch Dia-Sharp Sharpener, Credit Card Sized- Extra-Fine, Fine and Coarse Diamond -Set of 3 | | Item Dimensions L x W x H | 9.2L x 6W x 0.6H centimetres | | Item Type Name | Knife Sharpener | | Item Weight | 0.32 Ounces | | Item weight | 0.32 Ounces | | Manufacturer | Acme United Corporation | | Manufacturer Part Number | D3EFC | | Manufacturer Warranty Description | Guarantee – you acquire from dmt with purchase of our products in europe also a promise without restriction of your legal warranty rights.

I want to put one in my edc pouch that rides around in my cargo pocket. Will they snap easily if bumped or flexed?** A: I don't think there is any danger of snapping the Dia-Sharp card by accident (or on purpose, for that matter). The substrate appears to be steel, about 1.5x the thickness of a credit card, with the finishing surface diamond-impregnated. **Q: Has anybody tried cutting these in half....to potentially double your usage time?.otherwise, i find the middle doesnt get used, just the edges. ThankS** A: Never have tried to cut them in half. Haven't experienced your problem with wear either. love these little stones. They do wear out though. **Q: Is there any abrasive on the card edges?** A: Just had a look at mine--nope, no abrasive on the edge--the cards are really thin, so I don't there really could be, anyway. **Q: Can the cards be modified in any way? Like cutting down to size or drilling holes through them to attach to a lanyard or camping bag?** A: They are just metal cards with an adhesive matrix that diamond chips are embedded into. You can cut or drill them as you want, but be careful so as to not knock the diamond chips loose from the card. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These have been brilliant.

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. ## Frequently Bought Together - Diamond Machining Technology (DMT) Dia-Sharp Diamond Sharpening Stone Credit Card, Extra Fine, Fine & Coarse, 3 Pack - Trend Diamond Abrasive Lapping Fluid, 3.4 fl oz, Blue, Professional Grade Sharpening Fluid for Optimum Performance, DWS/LF/100 - DMT (Diamond Machining Technology) 2.5-in.
