Summary
A passive knife-sharpening plate from Diamond Machining Technology, described in its listing as an 8 × 3 × 0.38 inch continuous monocrystalline diamond surface at 6 micron / 4000 mesh, made in the USA with non-skid rubber feet. Before you buy, know that none of those details could be confirmed: the manufacturer’s site is behind a bot challenge and no independent test or owner discussion was readable.
Strengths
- A passive bench plate: no power, no plug, no water bath and no lubricant requirement is implied by any readable source.
- The listing describes a continuous monocrystalline diamond surface at a 6 micron / 4000 mesh grade.
- Non-skid rubber feet are listed, which implies a bench-stable plate.
- Ownership cost is limited to the plate plus an optional cleaner or compound; no consumable requirement was documented.
- It is a single plate with no battery, charger or scheduled maintenance routine.
Weaknesses
- The manufacturer’s page could not be read: the DMT site returned a bot challenge and a reader proxy was refused, so no spec sheet, manual or care instruction was confirmed.
- No independent test of this exact model was located, and no owner discussion could be read.
- The listing’s grit wording pairs “medium” and “extra-fine” with one mesh figure, so the grade is ambiguous until the maker’s label is read.
- “Made in USA” is a claim that no manufacturer or retailer source confirmed.
- No price could be read from a non-Amazon retailer, so value cannot be judged.
- Rockler, a large US sharpening channel, lists no DMT product in its sharpening-stone category.

Full research notes and sources
What it is
The 8-in Diamond Plate is a passive sharpening plate: a diamond abrasive surface on a bench-stable body, with no motor, no water bath and no power requirement. The listing describes an 8 × 3 × 0.38 inch plate with a continuous monocrystalline diamond face at 6 micron / 4000 mesh, made in the USA and supplied with non-skid rubber feet. Nothing else about the plate — its body material, its weight, whether the diamond is a solid face or a coating on a carrier — could be confirmed from a readable source.
Grade and surface
The listing’s grade wording is internally inconsistent: it pairs 6 micron / 4000 mesh with the words “medium extra-fine”, which are two different grade names for one surface. Treat the mesh number as the more specific claim and the grade word as unreliable until the maker’s page is read. The bigger open question is the face itself. The phrase “continuous monocrystalline diamond surface” does not settle whether the working face is a full solid-diamond plate or a diamond layer bonded to a carrier, and that distinction determines whether the plate can be re-flattened and how much stock it removes. The only authoritative place to check is the manufacturer’s page, which could not be read.
What could not be verified
Every specification above comes from the listing, not from an accessible manufacturer or independent source. The DMT site returned a bot challenge and a reader proxy for the same URL was refused; the archived dmt.com domain belongs to an unrelated consultancy with no sharpening content. Among US retailers, Home Depot, FishUSA and Ace Hardware returned 403, while Zoro, McMaster-Carr and True Value served script-only pages with no product data. Rockler was the exception: its pages parsed normally and show no trace of this product. Reddit’s search endpoint also returned 403, so no owner experience could be gathered.
Is it worth it?
No price could be read from a non-Amazon retailer, so no value threshold can be written. Before buying, confirm on the maker’s page whether the face is continuous diamond or a coated carrier, what the maker’s own label for 4000 mesh is, and the warranty term for US buyers. If the plate is carried by few large US retailers, price dispersion and replacement parts matter more than a few dollars of sticker price.
Which model this is
This page covers the listing titled “Diamond Machining Technology (DMT) 8-in Diamond Plate”, sold under ASIN B0094TMPOM. The identity could not be confirmed against a manufacturer catalogue: no DMT part or SKU number and no revision were readable, and the mapping between the listing title and a catalogue entry is unconfirmed. Do not merge it with DMT’s other whetstone lines — their 8-in, 10-in and 12-in plates, or their diamond-plate, CBN and solid lines and tabletop sharpeners — without a manufacturer page.
