Its durable metal construction requires no oil, works dry or wet, and comes with a 25-year warranty, making it the ultimate portable sharpening solution for professionals and enthusiasts alike. ## Description Since 1976, DMT has been in business to do just one thing: make the world’s best diamond sharpeners. Product innovations such as our signature polka-dot interrupted surface, and others with our continuous surface of high-performance diamond, are praised worldwide for their superior quality. From pocket-sized whetstones to heavy-duty bench stones, the difference arrives time and again through our undivided pursuit of sharpening excellence. For DMT products, no oil or pressure must be used to sharpen the tool or knife. Diamond Coverage differs widely from one manufacturer to the next. For long-lasting performance, DMT makes certain that each sharpening surface carries the most diamonds per square inch in the industry. Diamond Uniformity is also key to sharpener performance. DMT uses a proprietary process that ensures near-perfect consistency in grit size. The result is a micronised monocrystalline diamond that covers evenly across the sharpening surface to prove effective with every use, year after year. Surface Flatness can mean the difference between a well-honed tool and one that is barely serviceable. Flat surfaces maintain consistent, even contact with the edge to produce a bevel that carries the same degree of sharpness from end to end. DMT sharpeners are engineered to be the flattest on the market, and built to outlast other products, which are variable in surface, and often warped, hollowed or grooved. ## Features - Quick edge repair anywhere - Three different diamond stones: Extra-Fine to polish and refine an edge, Fine for a razor sharp edge and Coarse to transform a dull edge - Sharpens knives faster than conventional stones with DMT's micronized monocrystalline diamond surface - No oil is needed-sharpen dry or with water - Durable construction will provide years of performance and reliable service ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00004WFTD | | Best Sellers Rank | 283,737 in DIY & Tools (See Top 100 in DIY & Tools) 296 in Sharpening Stones | | Brand Name | DMT | | Colour | Grey | | Country Of Origin | USA | | Customer Reviews | 4.2 4.2 out of 5 stars (1,032) 4.2 out of 5 stars | | Global Trade Identification Number | 00017042001902 | | Grit Type | Coarse,Extra-fine,Fine | | Included Components | 1 x Diamond Whetstone Mini Diamond Stone - Coarse / Fine / Extra-Fine - Set of 3 | | Item Dimensions L X W X H | 5L x 140W x 40H millimetres | | Item Type Name | Knife Sharpener | | Item Weight | 53 Grams | | Manufacture Year | 2008 | | Manufacturer | Acme United Corporation | | Manufacturer Part Number | W7EFC | | 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.

Just, and I mean just big enough for most chisel, but plane blades will need something larger.These do sharpen enough to cut hairs off the back of your hand.Perfect for pen knives.I'll have to save my pennies for the larger ones. ## Frequently Bought Together - Diamond Machining Technology (DMT) W7EFC Diamond Whetstone Mini Diamond Stone - Coarse / Fine / Extra-Fine - Set of 3 - TOKO Edge Tuner Pro – Ski & Snowboard Edge Sharpener | Adjustable 85°-90° Angle Tuning Tool with Roller Bearings | Professional Ski & Snowboard File for Precise Edge Grinding - Swix Gummy Rubber Edge Tuning Soft/Hard Stones --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/49568570-dmt-w7efc-diamond-whetstone-mini-diamond-stone-coarse-fine-extra](https://www.desertcart.ma/products/49568570-dmt-w7efc-diamond-whetstone-mini-diamond-stone-coarse-fine-extra) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-09-01*
