RISAM Knife Sharpening Guide – maintains a stable angle of approx. 15° during manual sharpening

The RISAM RW009 knife sharpening guide is a practical tool for manually sharpening knives on water stones or diamond sharpeners. It helps maintain a consistent angle with every stroke—approximately 15°— thereby facilitating more even sharpening of both sides of the blade. The ceramic contact surfaces protect the guide when it comes into contact with the stone and extend its service life.

RISAM RW009: A Simple Tool for More Confident Knife Sharpening

Sharpening knives by hand on a whetstone requires finesse, patience, and, above all, a consistent angle. The RISAM RW009 guide helps beginners and home users keep the blade in a consistent position with every stroke. This reduces the risk of an inconsistent angle, which can slow down the sharpening process or create an irregular bevel.  Simply attach the guide to the blade; the ceramic part touches the surface of the whetstone or diamond sharpener as you work. As you move back and forth, it helps you guide the knife at a more consistent angle, allowing you to better focus on a smooth stroke, light pressure, and even sharpening along the entire length of the blade.

Why is a stable angle important when sharpening?

When sharpening a knife, the angle is one of the most important factors. If it changes during each stroke, the blade is sharpened unevenly and the result may not be as clean. The RISAM guide helps maintain an angle of approximately 15°, which is suitable for many kitchen knives and helps achieve sharper and more consistent bevels.  This doesn’t mean the guide replaces proper technique, but it significantly helps with mastering it. Thanks to it, users can better learn how to guide the blade across the stone, apply light pressure, and repeat the same motion on both sides of the edge.

Ceramic rollers for contact with the stone

The guide features ceramic rollers that come into contact with the whetstone or diamond sharpening stone during sharpening. Ceramic was chosen for its longer service life when rubbing against the grinding surface. This allows the guide to better withstand repeated use during home or hobby sharpening.  When working, it is important to apply light pressure and let the stone do the work. The guide is designed to help maintain the correct angle, not to be used as a tool for forcefully pressing the blade into the stone. Excessive pressure reduces control, can unnecessarily strain the blade, and accelerates wear on the grinding surface.

How to Use the Guide Correctly

Attach the guide to the sharpening edge of the knife blade. Hold the guide with one hand and the knife handle with the other. The ceramic part should touch the surface of the whetstone or diamond sharpener. Guide the knife back and forth across the stone using light pressure, then turn it over and repeat the process on the other side.  Move the guide along the entire length of the blade and repeat the process until the entire blade has been sharpened. After sharpening, clean the knife with a damp cloth or water and dry it immediately. Clean the surface of the guide with water and a soft brush to remove any remaining grinding slurry and metal particles.</ p>

What types of knives is the sharpening guide suitable for?

The guide can be used on knives with a blade height of at least 19 mm. This means it is primarily suitable for standard kitchen knives that have enough space to safely attach the guide. Typically, these include Gyuto, Santoku, Chef, Nakiri, Kiritsuke, or larger utility knives. For very low-profile blades, small paring knives, narrow filleting knives, or knives with atypical shapes, you’ll need to check whether the guide fits properly. If the blade is not tall enough or the guide cannot be attached securely, it is not recommended for use.

Guide and whetstone: A good combination for beginners

Sharpening on a whetstone is one of the best ways to restore the edge of a kitchen knife. However, beginners often struggle with maintaining the correct angle. The RISAM RW009 guide significantly simplifies this problem by helping to keep the blade in a more consistent position relative to the whetstone.  For regular home sharpening, a combination of a guide and a medium-fine whetstone works well—for example, #1000 grit to restore the edge and a finer stone for finishing. The guide helps with the angle, but the quality of the result is still influenced by proper stone preparation, even pressure, the number of strokes, and careful cleaning after sharpening.

Maintenance and Cleaning of the Sharpening Guide

Do not wash the sharpening rod in the dishwasher. After sharpening, metal particles, grinding slurry, and stone debris may accumulate on it. Remove these with a sponge under running water; baking soda on a sponge may also be used. The manufacturer does not recommend using dish soap.& nbsp;After washing, dry the handle thoroughly. Storing it in a dry place is important for cleanliness, longer lifespan, and safe use. Store the handle and sharpened knives out of the reach of children, as the blade may be significantly sharper after sharpening than before maintenance.

What the guide can and cannot do

The guide helps maintain the angle, but it won’t sharpen the knife on its own. The result still depends on a whetstone, a diamond sharpener, the correct technique, and patience. So think of the guide as a tool for a more consistent technique, not as an automatic substitute for experience. If the knife is very dull, has a damaged edge, a chipped blade, or needs its geometry adjusted, professional sharpening may be more appropriate. The guide is ideal mainly for routine home maintenance, practicing the angle, and repeated manual sharpening of standard kitchen knives.
