Your best knife should not be the one that tears the tomato. This 1mm diamond plate brings a dull edge back at the counter, by the campfire or on the road, with a few light strokes. At 150 by 63 millimeters and about 70 grams, it lives in the drawer instead of the cupboard.
Ultra-thin portable diamond sharpener with honeycomb surface that keeps dust from affecting sharpening
- Dull kitchen knives
- Bulky sharpening stones
- Clogging from metal dust during sharpening
Keep your kitchen knives sharp on a stone that fits in your pocket
Dull blades make every chop a chore. This thin diamond plate brings the edge back in minutes, without the bulky stone or the wait.
Thin enough to slip into any kitchen drawer

Thin, light, ready to travel
At 1mm thick and about 70g, the plate slides into a bag, a drawer or a camp kit where a bench stone would never fit. Keep it beside the knife block and forget about it until the blade starts dragging.

Honeycomb that keeps dust moving
The raised hexagonal grid keeps metal dust from settling on the working surface while you sharpen. The stone keeps cutting instead of clogging, so the edge you get is the one you were working toward.

Grit built for touch-ups
The 1000# diamond coating sits on one side only, and the grit is laser-etched so you know which face to use. It is made for regular maintenance on kitchen knives. A chipped blade or a heavy roll still needs a professional grind.
Light strokes, correct angle, quick test
- 1Set a low, steady angle
Hold the blade at a shallow angle against the plate. Light pressure lets the diamond face do the cutting.
- 2Make a few light strokes per side
Draw the blade across the stone in smooth passes, alternating sides. Keep the thin plate steady under your fingers.
- 3Test on paper
Slice a sheet of paper after a handful of strokes. A clean cut means the edge is back. If it tears or drags, keep going.
- 4Store it flat
Keep the plate lying flat in a drawer or pack pocket, away from other loose metal.

Questions and answers
1000# is a fine grit, so it is built for touch-ups and keeping a working edge sharp. It will not rebuild a badly rolled or chipped blade. For that, start on a coarser stone, then finish here.
The plate is a thin metal base with a diamond coating on one side. Light, even pressure keeps it flat in normal use. Heavy force is the fastest way to stress a thin plate, so let the diamond surface do the work.
The raised honeycomb grid keeps metal dust from sitting on the working surface during sharpening, so the diamond face keeps cutting. Wipe the plate clean after each session and it stays ready for the next touch-up.
Use it on the straight edge of the blade. Serrations do not sit well on a flat plate, so skip them. Thin, hard Japanese blades take well to the light strokes this stone is built for.
A pull-through sharpener removes steel fast and unevenly, and it rounds the edge over time. This plate lets you keep the existing bevel with a few controlled strokes. It is a one-time buy that keeps the knives you already own in service.
