Review: Excellent stone - really takes my edges to the next level - Without this stone, I can still get a pretty good edge with just the green X-fine but THIS stone defintely takes my edges to the next level - razor sharp and very polished. At the new price of $14, don't pass up on this. I paid $18 and they dropped the price right afterwards ... grrr :-) Maybe someday I'll also get setup for stropping with some diamond paste or 3m abrasive lapping pads but at the moment I don't feel that these are necessary for me since the DMT xxf does such a great job. I can literally shave with any of my edges honed with this stone. I'll usually complete a full v profile with this stone and then add a microbevel using ONLY this stone at the very end, with either 1 or 2 steps up on the aligner (depending on the blade). Works like a charm! My only complaint is that shipping took a while for this item, even though it was listed as in stock. Review: Great as honing steel replacement. Awsome stone. - Excellent stone when used in conjunction with the aligner kit. I've essentially phased out using my water stones in favor of the DMT system. These particular stones have a small break in period and will arrive feeling a little more aggressive than a typical waterstone of equal grit/micron size. It's not a problem, and after a couple of uses it will become superior in function compared to a water stone. No mud, always flat, fast cutting and it can be used dry. On carbon steel knives, with the right bevel angle you can very easily attain a 3 micron non-toothy edge that is literally hair whittling sharp. I currently use this particular DMT stone as a replacement for my honing steel/rod. Its certainly less convenient than a steel, but the tradeoff of being able to produce a much longer lasting edge than you can with a steel rod is worth the effort. ## Features - Knife Sharpening Stone: The micronized monocrystalline diamond surface of this blade sharpener quickly and easily sharpens dull knife and tool edges - Portable and Easy to Use: Diamond sharpening stone is portable and can be easily carried around in a pocket; Sharpen dry or with water – no need for messy oils - Versatile Usage: Knife sharpener stone can be used with our aligner or alone for proper tool maintenance by woodworkers, chefs, and other professionals who rely on the superior quality and versatility of DMT products - Durable Construction: Made from only the highest-quality materials, this 3 micron (8000 mesh) diamond stone will provide years of performance and reliable service - Made In The USA: DMT offers the most efficient sharpening tools on the planet, tools like this diamond knife sharpener – the fastest, easiest, and most effective tool for sharpening an edge - Portable pocket convenience - Extra Extra Fine diamond for the finest polished edge of al bonded diamond abrasives - Sharpens knives faster than conventional stones with DMT's monocrystalline diamond surface - No oil is needed-sharpen dry or with water - Durable construction will provide years of consistent performance and reliable service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001AU4LZO | | Best Sellers Rank | #481,598 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #998 in Sharpening Stones | | Brand | Diamond Machine Technology (DMT) | | Brand Name | Diamond Machine Technology (DMT) | | Color | Tan | | Customer Reviews | 4.6 out of 5 stars 175 Reviews | | Global Trade Identification Number | 00017042004569 | | Grit Type | Extra,Extra Fine | | Included Components | Diamond Whetstone | | Item Dimensions L x W x H | 4"L x 4"W x 4"H | | Item Type Name | fixed blade,hunting knife,outdoor,camping | | Item Weight | 27 Grams | | Manufacturer | DMT | | Manufacturer Part Number | A4EE | | Manufacturer Warranty Description | Manufacturer Warranty | | Material | Micronized Monocrystalline Diamond | | Material Type | Micronized Monocrystalline Diamond | | Model Number | A4EE | | Number of Items | 1 | | Product Dimensions | 4"L x 4"W x 4"H | | UPC | 017042004569 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Diamond Machine Technology (DMT) - **Color:** Tan - **Global Trade Identification Number:** 00017042004569 - **Grit Type:** Extra,Extra Fine - **Item Weight:** 27 Grams - **Manufacturer:** DMT - **Material:** Micronized Monocrystalline Diamond - **Number of Items:** 1 - **Product Dimensions:** 4"L x 4"W x 4"H - **UPC:** 017042004569 ## Images ![DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Image 1](https://m.media-amazon.com/images/I/61A+RlODeKL.jpg) ![DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Image 2](https://m.media-amazon.com/images/I/81fyirQVkHL.jpg) ![DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Image 3](https://m.media-amazon.com/images/I/61DsVx+VBVL.jpg) ![DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Image 4](https://m.media-amazon.com/images/I/61tjil7N4OL.jpg) ![DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Image 5](https://m.media-amazon.com/images/I/61BQgoph2yL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent stone - really takes my edges to the next level *by J***K on November 3, 2011* Without this stone, I can still get a pretty good edge with just the green X-fine but THIS stone defintely takes my edges to the next level - razor sharp and very polished.

Awsome stone. *by N***O on August 13, 2013* Excellent stone when used in conjunction with the aligner kit. I've essentially phased out using my water stones in favor of the DMT system.

This is the final step in sharpening a blade that you want to put a razor's edge on. This stone, by itself, won't do much on a dull blade. You must use coarser stones first. I purchased this in addition to the DMT Deluxe Aligner. I also purchased an extra coarse stone, so I have a total of five stones to sharpen with. (This stone is probably the least important of the stones.) There is a discrepancy on the packaging with regards to the grit of this stone. The packaging says this is a 2200 mesh stone. This is inconsistent with DMT's literature and web site which state that white is 2200 mesh, and tan is 8000 mesh. So I emailed DMT. Here is what they said: "The web sites are correct. The tan is 8000 mesh. On the packaging the color was changed from white (ceramic) to tan, but the mesh was not changed by oversight. Sorry for any inconvenience this has caused. Thank you for choosing DMT products. Let me know if you have any further questions or concerns. Have a great day! Giving you the Edge, Kristina Byron DMT Customer Care Tel 508-481-5944 Fax 508-485-3924 [...] The stone itself gets five stars, but minus one star for the discrepancy on the packaging. ## Frequently Bought Together - DMT A4EE Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Extra Fine - Diamond Machining Technology (DMT) A-PROKIT Dia-Sharp Whetstone Sharpening Kit With Diamond Sharpening Stones - DMT A4X Whetstone Knife Sharpener and Diamond Sharpening Stone for Use with Aligner, 4 Inches, Extra Coarse --- ## 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.co.uk/products/6924700-dmt-a4ee-whetstone-knife-sharpener-and-diamond-sharpening-stone-use](https://www.desertcart.co.uk/products/6924700-dmt-a4ee-whetstone-knife-sharpener-and-diamond-sharpening-stone-use) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-11*
