Advanced sharpening stone set RISAM including flattener and holder

The Japanese-type RISAM sharpening stone will breathe new life into your knives! At an affordable price, your kitchen, chef, and hunting knives will gain the sharpness you have always dreamed of. They will become even sharper than when you first bought them. Even the best knife made from the finest materials loses its original sharpness over time. That’s why it is necessary to sharpen knives regularly and maintain their cutting edge. With the correct technique and sharpening stones from Dellinger, this task becomes easy.

RISAM sharpening stones are made from high-quality corundum (aluminum oxide). This material is extremely durable and provides maximum sharpening performance. Thanks to its versatility, you can use the stone not only on knives but also on scissors, axes, razors, chisels, pocket, and hunting knives. Synthetic sharpening stones are generally made from aluminum oxide, the same abrasive used in oil stones. The difference is the bonding material: water stones are softer than oil stones, which allows for faster sharpening. During sharpening, worn abrasive particles break away and are replaced by fresh sharp material. This makes sharpening much quicker. Another advantage is the use of water instead of oil to remove metal particles. However, water stones are not perfect: their softness causes faster and uneven wear, which requires regular flattening. That’s where flattening blocks come into play, which you can find in our sharpening accessories.
