Poseidon - At last I have found a Western style fish filleting knife that I really like.

This long, slim blade has been crafted to fillet small to medium-sized fish. From fresh to salt water, Poseidon has enough flex to run along the spine of fish while being sharp enough to remove the spine and trim and unwanted parts with ease. These knives are made in limited numbers, so if this is what you are looking for, get in quick,

Knife Style: Fish Filleting
Blade Length: 223mm
Width: 26mm

Total Length: 350mm
Weight: 132g
Handle: Padauk

About Cain & Abel knives: The carbon steel used in Cain & Abel blades is from recycled leaf springs from heavy trucks & Russian war trucks that served in the Vietnamese war. The steel is 5180. This spring steel is a tough form of steel with a higher Carbon makeup. The higher Carbon reduces toughness, but increases wear resistance and attainable hardness. The steel is heat treated, giving the knives an HRC of around 60.

HRC stands for Rockwell hardness, which refers to the level of hardness the steel has. Japanese knives are usually between 60 to 63 HRC. They can be easily re-sharpened and hold an excellent edge because of the makeup of the steel.
