Sharpal Holdbubble Sharpening Angle Guide

The Sharpal Holdbubble Sharpening Angle Guide uses a magnetic base and integrated bubble level to maintain consistent sharpening angles from 15° to 45° across whetstones and other sharpening systems.

• Adjustable from 15° to 45° — Set your desired sharpening angle and lock it in, covering everything from razor-sharp kitchen knives to durable outdoor blades with precise control.
• Magnetic Base Holds Position During Sharpening — Attaches securely to knife blades at 90° to the cutting edge, staying in place throughout your sharpening strokes so you can check your angle without interruption.
• Integrated Bubble Level for Visual Feedback — Watch the bubble to maintain consistent angle on each pass, preventing over-sharpening and uneven edges that ruin blade geometry.
• Works with Any Sharpening System — Compatible with whetstones, diamond stones, ceramic rods, and other sharpeners for knives, scissors, chisels, and plane irons in a compact, portable design.

The Sharpal Holdbubble Angle Guide

The Holdbubble fixes the biggest problem with freehand sharpening: keeping a consistent angle. Most people rock the blade during sharpening without realizing it, creating rounded or uneven edges that don't cut well and wear out faster. The magnetic base sticks to your blade while you work, and the bubble level gives you instant visual feedback when your angle drifts. Set it once to your preferred angle and the patented design maintains accuracy regardless of blade size or shape.
