About the Shape - The Honesuki is a Japanese style boning knife. Originally designed for poultry and small animals like rabbit, it excels for many larger butchering and fish filleting work. It has a relatively thick heel for scraping meat from bones, and a thinner tip for precise cuts. You don't want to force this knife through bone, but it's perfect for cutting through cartilage and tendons.
About Masakage Koishi - These knives have been named Koishi (pebbles) for the tsuchime (hammered) and kurouchi (black) finish that give the impression of river pebbles. With the octagonal cherry wood and black pakka handle, the overall balance and feel is what chefs desire and makes it a Culinary Badass. Think Chuck Norris, but if he was a kitchen knife.
Aogami Super is the king of knife steel - super easy to sharpen, gets a laser beam edge, cuts like silk and is very rugged for its hardness. It’s called SUPER for a reason. The outer layer is stainless steel, making this knife very easy to maintain.
