Knife Straightening Stick

The Knife Straightening Stick is a specialist tool for correcting minor warps and bends in Japanese knife blades. San mai and kasumi-construction knives have a softer outer cladding over a hard steel core - this softer layer can flex and take on a slight set if lateral pressure is applied during use or storage. Left uncorrected, even a minor warp affects cutting performance and makes accurate sharpening harder to achieve.

Made from hard maple, this is the same type of tool used by Japanese blacksmiths and professional knife shops. Work slowly and deliberately - the goal is gradual correction with light, controlled pressure applied at the right point along the blade. Do not try to force a correction in one pass. An essential item for anyone who collects and uses Japanese knives regularly and wants to keep their blades performing at their best.
