Polax oval whetstone 230 x 35 x 13 mm, model 28-001

Polax oval whetstone 230 x 35 x 13 mm, model 28-001 is a handheld sharpening stone designed for maintaining and restoring cutting edges on knives, gardening tools and small blades. Its elongated oval shape and compact dimensions allow controlled movement along both straight and curved edges, while the moderate thickness ensures stable contact and predictable results during honing. The stone is intended for routine maintenance and touch-up sharpening in homes, workshops and mobile service situations.

Advantages

The oval profile gives improved access to rounded bevels and recessed areas that are difficult to reach with rectangular stones. Its 230 x 35 mm working surface balances edge coverage and precision, enabling even wear and consistent sharpening across the blade length. The size and shape make the stone easy to grip and maneuver for single-hand use, and the thickness of 13 mm provides sufficient support to prevent excessive flexing during pressure application. The tool is portable, simple to store, and suitable for repeated use without complex setup.

Suitable for

• Kitchen knives and pocket knives
• Garden and pruning tools (shears, secateurs)
• Small woodworking blades and chisels
• On-site touch-up sharpening for tradespeople and hobbyists

How to use

Secure the blade or hold it steadily and place the whetstone on a non-slip surface or use a stone holder if available. Wet the stone if it is intended for use with water or apply appropriate lubricant according to the stone material. Maintain a consistent angle between the blade and the stone and move the blade along the length of the stone using smooth, controlled strokes from heel to tip. Repeat the same number of strokes on both sides of the blade to preserve bevel symmetry, checking the edge periodically until the desired sharpness is achieved. After sharpening, clean the blade and the stone surface and dry both thoroughly before storage.

Usage recommendations

Use light to moderate pressure and maintain a steady angle to avoid removing excessive material. If the stone requires wetting, follow the manufacturer guidance on lubricant type and soaking time. Store the whetstone in a dry place and inspect it for even wear; flatten the surface when necessary to maintain effective sharpening performance.
