Japanese knife maintenance: Best magnetic blocks and cutting boards

With Japanese knife sales increasing by 34% since 2023, there is a growing emphasis on proper maintenance and storage to protect high-carbon, brittle steel edges.

To prevent damage to delicate blades like gyutos or santokus, experts recommend using magnetic knife blocks rather than traditional slotted blocks. Magnetic holders use rare-earth magnets to grip blades without the risk of scraping edges against other metal or being cramped in compartments. Top-rated models include the HOSHANHO 14-Inch Double-Sided Magnetic Knife Block and the NULAS Magnetic Knife Block, which features a built-in sharpener.

Selecting the correct cutting surface is equally critical to prevent chipping. Hinoki (Japanese cypress) wood is highly recommended due to its medium-soft texture that provides a gentle ‘give’ under the blade, preserving sharpness. Notable options include Shun Hinoki wooden cutting boards and various cypress products from brands like Yoshihiro and Kai Seki Magoroku.
