Coming Soon! (September 2025)
A full-size 200×70 mm bench stone with a thick 5–7 mm diamond layer.
Built for freehand sharpening: fast cutting, long lasting, and unmatched tactile feedback.
This is my 6 micron resin-bonded diamond sharpening stone — the first pre-production run. While the backing shows some cosmetic imperfections and machining marks, the abrasive surface itself is flawless.
What will change?
The 6µm formula you see here is final: when production begins, only the presentation and price will change (cleaner packaging and a tidier backing). The performance you experience is exactly what I designed it to be. I aim to keep the price as low as possible but it may change for the production version.
Size & Thickness
This is a full-size 200 × 70 mm bench stone with a generously thick abrasive layer. I aim for a 5 mm diamond layer, but to allow proper lapping, stones are intentionally made oversized — typically between 6–7 mm. After flattening, most end up around 6.5 mm, but every stone will be at least 5 mm thick in abrasive.
Performance
This stone was built specifically with freehand sharpening in mind. I’ve focused on four attributes:
-
Tactile and auditory feedback — you feel and hear what’s happening at the edge.
-
Speed — fast, consistent abrasion.
-
Longevity — a hard resin bond that resists wear.
-
Slow loading — it keeps cutting cleanly, longer.
With abrasives, there are always trade-offs. The harder resin means it won’t leave quite as bright a polish as a softer bond — but that’s exactly what gives this stone its superb feedback, durability, and consistency. And if you want a flawless mirror finish, a quick progression onto a strop will deliver it effortlessly, so you’re not losing anything in practice.
Comparisons
-
Like an improved Venev 800 FEPA-F (7/5µm): clearer finish, better feedback, slower loading.
-
Not quite as mirror-clean as a 5µm CGSW, but without the drawbacks — no fast wear, no quick loading, and no vague, mushy feel.
Coming Soon
I’ll be releasing a demonstration video soon to show exactly how this stone performs in practice.
