Know before you buy
This knife is specifically designed for butchering and cleaning whole fish. Its thick, robust blade is engineered to handle the resistance of fish bones and tough skin while maintaining the precision needed for clean filleting.
Yes, because the blade is single-beveled, it is sharpened primarily on one side to create a precise, razor-sharp edge. You will need to maintain this specific angle during sharpening to preserve the knife's performance and geometry.
Ginsan steel offers the high-performance sharpness and edge retention of traditional carbon steel but with the added benefit of being stainless. This makes it much more resistant to rust and corrosion, requiring less maintenance after contact with moisture.
Ho-wood is a traditional, lightweight choice that provides a comfortable, natural grip. While it is durable, it is a porous wood, so you should avoid soaking it in water and ensure it is dried thoroughly after cleaning to prevent the wood from swelling or cracking.
No, you should avoid using this knife on frozen items or heavy bones. While the blade is robust enough for fish, the hard Ginsan steel edge is thin and can chip if subjected to the extreme impact or torque required for frozen foods or dense meat bones.
The high heat, harsh detergents, and physical movement within a dishwasher can damage the delicate edge of the blade and cause the natural wood handle to warp or split. Hand washing and immediate drying are essential to maintain the integrity of this hand-forged tool.
