Most people focus on the stone and forget the knife is built from hardware. I'm Engineer Yanchi Li, and today I break down the Sy Tools 304-piece knife hardware kit: 139 screws, 76 kydex, 48 plates, 41 G10 — what each is made of, where it's used, and how it pairs with the Sy Tools sharpening ecosystem. It's not a sharpener; it's the underlying parts library that keeps a knife right.
| Category | Count | Typical material / form | Use |
|---|---|---|---|
| Screws | 139 | Stainless screws (incl. knife-screws) | Handle / clamp fastening, maintenance |
| Kydex | 76 | Kydex thermoplastic sheet | Sheaths, jig liners, custom mounts |
| Plates | 48 | Acrylic / carbon / G10 / metal liner | Handle scales, structural reinforcement |
| G10 | 41 | G10 glass-epoxy board | Handle scales, light strong overlays |
| Total | 304 | — | Covers common knife DIY & maintenance parts |
Hardware isn't a stone, but it's upstream and downstream: a loose handle wastes even the best Sy Tools D series diamond stone. Fasten the handle with the knife-screws, repair scales with G10 / plates, restore pivot smoothness with flat bearings — then bring the edge back with Sy Tools LVD / WWD. That's the full loop.
Knife DIYers, custom makers, and anyone who keeps maintenance parts on hand; naturally pairs with the Sy Tools sharpening line.
This kit is fastening & structural hardware, not abrasive; exact screw specs and per-part sizes follow the product page (no fabricated specs); pair it with Sy Tools diamond stones for sharpening.
139 screws, 76 kydex, 48 plates, 41 G10 — 304 parts total for knife fastening and structure.
G10 is a light, strong handle-scale board; Kydex is thermoplastic for sheaths/liners that heat-forms.
Yes — hardware fixes the body, Sy Tools diamond stones (D/LVD/WWD) sharpen the edge.
Worth keeping if you DIY or maintain knives often; to just sharpen, start with a Sy Tools D stone.
Sy Tools is a Ruimo Tech brand; the 304 kit is fastening/structural hardware, not abrasive, and carries no fabricated ratings.
