Spyderco Tri-Angle Sharpmaker Knife Sharpening System — Compact Ceramic Stones, 30°/40° Guides

The Spyderco Tri‑Angle Sharpmaker is a compact ceramic sharpening system that teaches consistent edge angles for knives, serrations, scissors and tools with repeatable results.

Designed to simplify blade maintenance, the Tri‑Angle Sharpmaker blends a simple plastic base, keyed angle guides and two grades of alumina ceramic stones so anyone can restore and refine cutting edges. With a small footprint and protective storage lid, it fits in a workshop drawer, kitchen cabinet or gear bag. The system uses two preset angle positions (30° and 40°) to establish reliable edge geometry without guesswork, and its rounded stone corners address both straight and serrated edges.

How does the Sharpmaker create the correct sharpening angle?

The ABS base has keyed holes that hold the ceramic rods at two fixed positions, producing either a 30° inclusive angle for thinner edges or a 40° inclusive angle for more durable, working edges. This removes angle estimation from the process so users get repeatable results every time.

• Keyed holes lock rods in precise 30° or 40° positions.
• Simple vertical strokes maintain a uniform bevel.
• Consistent geometry prolongs blade performance between sessions.

What stones and grits are included, and what do they do?

The set includes two pairs of alumina ceramic stones: medium‑grit brown stones for shaping dull edges and removing nicks, and fine‑grit white stones for polishing and refining a keen, durable finish. The combination covers typical sharpening needs from restoration to finishing.

• Brown medium stones remove metal quickly for edge reprofile.
• White fine stones refine and polish for a cleaner cut.
• Use brown first, then white to achieve a refined edge.

Can I sharpen serrations, scissors, and other tools with this system?

Yes. The Sharpmaker’s rounded stone edges let you address serrated blades and detail work, while the rod setup is also well suited to scissors, awls and many hand tools. Small, controlled strokes and appropriate rod orientation handle different profiles safely.

• Rounded stone corners conform to serrations for precise touch ups.
• Scissors and awls can be sharpened by adjusting rod placement and stroke direction.
• Aluminum safety rods protect fingers during use and storage.

How portable and safe is the system for home or outdoor use?

The Sharpmaker stores all components inside the protective ABS base and lid, and aluminum safety rods shield hands while sharpening. Its compact design makes it easy to toss into a toolbox, camping kit or kitchen drawer without risking chipped stones or exposed edges.

• All parts snap together for secure, self‑contained storage.
• Lightweight and compact for travel or small workspaces.
• Safety rods minimize contact with exposed stones and blades.

Who is this for: The Spyderco Tri‑Angle Sharpmaker is ideal for cooks, outdoorspeople, hobbyists and tradespeople who want a straightforward, dependable sharpening method without mastering freehand angle work. It suits beginners who need guided setup and intermediate users who value a compact, repeatable system for maintaining knives, serrations, scissors and common hand tools.
