Work Sharp Blade Grinder Attachment for Ken Onion Edition MK.1 — Adjustable 10° to 35°

Overview

The Work Sharp Blade Grinder Attachment for the Ken Onion Edition MK.1 is a horizontal belt system designed to help you shape, sharpen, and hone knives and tools at home. This 4-pulley setup brings a high degree of control, letting you tailor the blade edge to your preferred feel and performance. Because it’s an attachment, it works in concert with the MK.1 sharpener, not with the MK.2, so compatibility is a key consideration as you plan your toolkit.

Key Features and Benefits

• Adjustable edge angles from 10° to 35° in 1° steps, enabling precise edge geometry for different blade styles.
• Full belt range included with 1" x 18" engineered belts, offering a wide spectrum of grits to suit shaping, sharpening, and honing tasks.
• Belt speed is adjustable from 1200 SFM to 2800 SFM, allowing you to match the task to the belt and edge type.
• Four-pulley design supports consistent tracking and a stable workflow during blade work.
• Includes optional high-density cotton belt for power stropping and edge refinement when desired.
• Attachment-only configuration supports easy integration into a compatible MK.1 setup, designed to emulate professional blade-making workflows at home.

Practical Uses and Real-Life Scenarios

Imagine shaping a new edge on a kitchen knife, then refining it with a finer grit belt to achieve a clean, ready-to-use feel. Or lay out a rugged edge on a hunting or outdoor blade, testing the edge through light cutting tasks to gauge performance. The adjustable angles help you experiment with profile geometry—without needing a full workshop setup—so you can discover what edge characteristics best suit your daily tasks.

In a hobbyist workshop, the belt speed range gives you options from aggressive reshaping to gentle honing, enabling you to move from rough shaping to fine finishing in a single setup. The belt assortment and optional stropping belt provide a cohesive system for edge maintenance, from initial bevel creation to final refinement.

What’s Included and How to Use

• Includes five 1" x 18" engineered abrasive belts across a range of grits for versatile blade work.
• Optional high-density cotton belt for power stropping to polish and refine the edge.
• Designed to be used with the Work Sharp Ken Onion MK.1 Edition sharpener for best results.

Note: This is an attachment-only product. To use it, pair it with a compatible MK.1 sharpener. It is not designed for the Ken Onion MK.2 model.
