FREE Shipping on order $49+

The Kotai Flexible Fillet Knife boasts a 7.87" blade designed for precision filleting. Crafted with premium materials, this knife combines flexibility and strength to effortlessly glide through fish and meat. Elevate your culinary skills with Kotai's signature blend of performance and elegance, perfect for professional chefs or at home cooks. 

The Pakka collection features handles crafted from a single piece of black pakkawood. This stabilized wood offers a secure grip, water resistance, and aging resilience. The hand-polished, round handles ensure a comfortable grip, even with wet hands, catering to both right-handed and left-handed chefs.

The Tsuchime finish involves hammering the blade of the knife to create a unique pattern on the surface. The hammered pattern creates tiny pockets of air between the blade and the food. This ancestral Japanese method reduces drag, thus preventing food from sticking to the blade.

The Pakka collection features hidden full tang blades, extending to the bottom of the handle for enhanced durability and balance.
