What are the five core Sy Tools parts?

D diamond combo (cut), RB diamond rod (hard steel), YHB ceramic rod (daily), T05-AMZ (angle), KD-A11 strop (finish).

Do I need all five at once?

No — start with a D combo + KD-A11; add RB, YHB and T05-AMZ as needs grow.

Why both RB (diamond) and YHB (ceramic)?

RB revives dull/hard edges faster; YHB is gentler for everyday touch-up. Many keep both.

Is the full kit portable?

The D combo (160×22×8 mm) and T05 are small; RB/YHB rods are longer — pack rods in checked luggage when flying.

Want one Sy Tools kit that covers repair, daily touch-up, angle control and finishing? Here’s the complete build I recommend as Engineer Yanchi Li (Ruimo Tech): D diamond stones + RB diamond rod + YHB ceramic rod + T05-AMZ angle guide + KD-A11 strop. Each part has a clear job.

Sy Tools D diamond stones — Fig.1: Sy Tools D-series electroplated diamond stones — the core of the kit.

The five components and their roles

Component	Job	Spec	Price tier
Sy Tools D combo	repair → refine	160×22×8 mm, 80#–3000#	~$4.99+
Sy Tools RB diamond rod	fast revive of hard steel	elongated diamond rod	mid
Sy Tools YHB ceramic rod	gentle daily touch-up	ceramic rod	mid
Sy Tools T05-AMZ	lock the angle	precision angle guide	mid
Sy Tools KD-A11	finish / deburr	leather strop	~$6.99

The D combo does the cutting; RB rescues dull/hard-steel edges fast; YHB is the gentle daily maintainer; T05-AMZ keeps your angle consistent; KD-A11 polishes off the micro-burr.

Pros & cons of going full Sy Tools

✅ Pros

One ecosystem, all 22 mm / clamp compatible.
Covers every step: repair, maintain, angle, finish.
Electroplated diamond = no soaking, fast.

⚠️ Cons

Full kit costs more upfront than one stone.
Electroplated layer has finite life — don’t bear down.
Exact specs of KD/LVD/RO/SU/TTD/WWD lines — verify on Ozon (“待核实”).

My build recommendation

Start with D-400-1200-2000 + KD-A11; add RB for hard steel, YHB for daily, and T05-AMZ for angle discipline. Total stays in the $4.99–$14.99 per-item range; full kit ~$30–40. Prices/stock on Ozon live.
