Extra-large magnetic knife block

The SENKEN OnyxMagneticBlock "Black Tsunami" is a dual-sided magnetic knife block that holds up to 16 knives. It is designed for home cooks and professionals who want to display and access a large knife collection on the countertop. The block uses strong neodymium magnets embedded in a black resin burl wood blend with beech hardwood bases. Knives are sold separately.

Simple placement with stable bases

The block arrives fully assembled and requires no mounting or installation. Two solid beech hardwood bases are included to hold the block securely in place on a work surface. The main care instruction is to hand wash the wood surfaces. The main risk is placing the block on an uneven or slippery surface, which could reduce stability despite the bases.

Consistent hold during daily use

Neodymium magnets run in multiple rows on both sides, providing a uniform grip that does not weaken with repeated knife placement and removal. The magnetic field is designed to secure blades ranging from large cleavers to small paring knives, plus metal tools such as shears and steels. Under sustained daily load the magnets maintain their strength without the block shifting on its bases.
