1000-Grit Whetstone

A whetstone is an essential tool for restoring a knife whose edge has begun to dull, bringing it back to a practical, working sharpness. Well-suited to regular maintenance, this 1000-grit whetstone plays a key role in keeping your knives performing reliably over time.

Before use, soak the whetstone in water for about 20 minutes. When sharpening, place a damp cloth or towel underneath to keep the stone stable. As the stone absorbs water, a fine slurry forms on the surface, allowing the blade to be sharpened evenly and gently. The moisture also helps reduce friction and heat, enabling smoother, more controlled movement of the blade.

When sharpening either side of the edge, it is recommended to maintain an angle of approximately 15 degrees against the stone. Progress can be checked by feeling for a light burr along the edge, which indicates that the blade has been properly worked.

Suitable for knives of all materials, a single whetstone allows you to care for your existing knives with confidence and extend their usable life. Please refer to the included sharpening guide to incorporate it into your routine maintenance.

Fukube Kaji

Fukube Kaji is a blacksmith workshop on the Noto Peninsula, founded in 1908. As a local nokaji rooted in Noto—where the sea and mountains sit close together—it has long made durable, practical tools, including woodcutting knives, fishermen’s tools, and kitchen knives, drawing on knowledge shaped by the region’s environment and daily life. In addition to tools needed locally, the workshop also works on the development and restoration of tools required in traditional culture and industrial fields across Japan.

Fukube Kaji starts by understanding the problems, then makes the tool to solve them. Each piece is made to support the user’s work and everyday life.
