Kai 120 grinding stone

A sharp knife is safer and more efficient: it requires less force and delivers precise cuts. A dull blade can slip and increase the risk of accidents.

It depends on how often you use them and the type of blade. Generally, regular honing with a honing steel is recommended, along with deeper sharpening every few months or when the knife loses effectiveness.

A honing steel maintains the edge and prolongs the life of the knife, but it doesn’t actually sharpen. To restore the edge, you need a sharpener (manual, electric, or whetstone). The ideal routine is to use both: the honing steel for daily care, the sharpener for periodic maintenance.

A smooth steel realigns the edge without removing metal. A grooved one has a slightly abrasive action, taking off a small amount of material. A ceramic steel is gentler and suitable even for hard blades like Japanese knives.

Hold the steel vertically and draw the blade across both sides at a 15–20° angle using light, steady strokes. Just a few passes are enough to maintain the edge.

Almost all types, but be careful with serrated or ceramic blades: they require specific tools or techniques. Always check the manufacturer's guidelines or ask us for advice.
