Whetstone triangle Müller 16×150 mm, fine corundum abrasive (3‑sided)

Müller triangular whetstone 16×150 mm made of fine corundum abrasive is designed for controlled sharpening of a wide range of cutting tools. The three‑sided triangular form offers stable flat and angled surfaces for finishing and restoring edges on kitchen knives, woodworking chisels, scissors and small blades. Its compact 16×150 mm size fits bench setups and portable sharpening tasks, while the fine grit produces a refined cutting edge with modest material removal for accurate edge geometry.

Advantages

The fine corundum abrasive provides consistent cutting action and long service life while reducing clogging during use. The triangular profile gives three distinct working faces to support flat honing and shallow bevels without additional jigs. The compact dimensions make the stone easy to position on a bench or carry for field use, and the rigid abrasive matrix maintains shape and flatness under light to moderate pressure.

Suitable for

• Kitchen knives and pocket knives
• Woodworking chisels and carving tools
• Scissors and shears
• Small blades and craft knives

Key specifications

• Shape: triangular, three working faces
• Dimensions: 16 × 150 mm
• Abrasive: fine corundum (aluminium oxide)
• Grit: fine (for refined edges and controlled removal)
• Typical applications: finishing, edge refinement, light reprofiling

How to use

Secure the whetstone on a stable surface before sharpening. If recommended by the tool manufacturer, soak or wet the stone according to accepted practice for this abrasive type; otherwise use with minimal lubrication such as water to limit dust. Hold the blade at the desired angle and draw it along a chosen face of the triangle, maintaining consistent pressure and stroke length. Use different faces or angles to address flat bevels or narrow edges, and work both sides of the blade evenly until the desired sharpness and edge geometry are achieved. Clean the stone after use to remove swarf and dry before storage.

Usage recommendations

For best results, combine the fine corundum whetstone with a coarser abrasive for initial reprofiling when edges are dull, then finish with this fine stone to refine the burr and polish the edge. Store the stone in a dry place and avoid heavy impact or uneven pressure that could chip the abrasive matrix.
