Where are DMT Sharpening Stones Made?

Since 1976, DMT Sharpening Stones have been manufactured in Massachusetts. The company offers products ranging from home use to professionals and large commercial operations. Today, DMT partners with high-quality brands to globally distribute their sharpening solutions.

What are DMT Sharpening stones made of?

DMT stones are made of micronized monocrystalline diamonds that evenly cover the surface of the sharpener. Currently, DMT stones contain the most diamonds per square inch in the industry.

Using diamonds as a sharpener produces a clean blade with a razor-sharp edge. On the other hand, a drag-through sharpener leaves metal burrs on the blade that flake off during use.

Diamond sharpening stones are also incredibly durable, so they'll last you a long time without needing to be replaced.

How do you clean a DMT Sharpening stone?

After each use, wet the DMT Sharpening Stone with water and wipe then wipe it off with a rag. It’s important to do this after each use so the residue doesn’t clog up the diamonds. Then, dry the sharpener before storing it.

Occasionally, use any cleanser and a nylon pad to scrub the DMT Sharpening Stone. Again, make sure the sharpener is dry before you store it.

Testimonials

Great, my item was more affordable here then elsewhere, got answers to my requests via email in a quick manner, my item shipped to me in 2 days via puralator, got my tracking number right after check out! Can't say enough good things.

Excellent and friendly service. Orders ship fast and they were able to help me find a missing part for my Tormek sharpening system with great ease. I highly recommend Big Bear Tools.

I have made several purchases from Big Bear Tools before and was previously impressed with the quick service. Considering this was a $400 purchase I was most relieved. Big Bear Tools is great!

Highly recommend Big Bear Tools!... Their service is fast and awesome! I've been dealing with Big Bear for years now, and have always been impressed every time I speak with them and place orders.

Not a big order today but BIG service. I needed a part. They had it. Easy to reach. Quick feedback. That felt good! Thank you!

Definitely recommend Big Bear Tools. Dave was great to deal with. Shipping was super fast. Will be dealing with them in the future. Very pleased. Thanks.
