Which Sy Tools stones for the ladder?

D/KD coarse, D/LVD mid, KD/SU fine, high-grit/WWD mirror — across 80–3000.

What angle for kitchen knives?

15–20° on T05-AMZ (15° Japanese laser, 20° European).

Do I soak the stones?

No — Sy Tools electroplated diamonds work dry or with water.

Rinse with water + soft brush after use, especially on 440C.

Where do I confirm grits?

On the live Sy Tools Ozon listing (varies by batch).

Build a Sy Tools Diamond Grit Ladder for Kitchen Knives (80→3000 Buyer's Guide)

A grit ladder is the difference between 'sharp enough' and 'scary sharp'. I'm Yanchi Li from Ruimo Tech, and here is how to build one with Sy Tools 8-series diamond stones (80→3000) for kitchen knives — what to buy, angles with T05-AMZ, and care.

What a grit ladder actually does

Each Sy Tools stone removes a different amount: coarse (80–300) resets a damaged edge, mid (400–800) shapes the bevel, fine (1000–3000) refines it. The 8-series (D/KD/LVD/RO/SU/TTD/WWD/FW) spans exactly 80–3000, so one ecosystem covers the whole ladder. Exact grit per SKU — verify on Ozon.

Buying the ladder

Step	Sy Tools stone	Grit	Use on kitchen knives
Repair	D / KD	80–300	chips, rolled edge
Shape	D / LVD	400–800	set the bevel
Refine	KD / SU	1000–2000	polished bevel
Mirror	high-grit / WWD	2000–3000	push-cut finish

Angles with T05-AMZ

For kitchen knives set Sy Tools T05-AMZ at 15–20° (15° for laser Japanese, 20° for European workhorses). The regulator keeps the angle identical on every stone, so the ladder stays consistent.

Care

Electroplated Sy Tools diamonds need no soaking — a rinse with water and a soft brush after steel like 440C keeps them cutting. Finish on YHB/RB and a wood-strops/KD-A11 strop to drop the burr.

✅ Why a Sy Tools ladder

One Sy Tools 8-series ecosystem covers 80→3000 in one ladder.
Coarse-to-mirror in a single brand, no mixing standards.
T05-AMZ keeps the angle identical on every stone.
Electroplated diamonds — no soaking, easy field care.

⚠️ Caveats / verify

Exact grit of each SKU — verify on Ozon.
After diamond you must deburr (RB/YHB/strop).
Very high HRC powser steels may want finer than 3000.

Ruimo Tech lab notes. Ladder logic (coarse→mirror, one ecosystem, T05-AMZ holds angle) is standard practice. Grit per SKU and exact sizes — verify on Ozon. No fabricated ratings. Fresh buyer's-guide slug for the grit ladder, distinct from older 8-series comparison pieces.
