Description: A utility knife is between a chef’s knife and a paring knife, with a narrower and straighter blade. This makes it perfect for a multitude of small tasks where more precise cuts are needed, such as trimming broccoli, green beans, or other smaller vegetables. Some cooks like to use it in their hand, too—almost like a large paring knife. Others like its smaller size as an alternative to the chef’s knife. Utility knives are sometimes called sandwich knives because they work well on almost everything that goes into a sandwich—from thin-skinned vegetables such as tomatoes, to meats and cheeses.
Sumio Kawamura is a third generation bladesmith working in a small forge in Niigata. Born in 1948, he began making knives at 25 years old. Though he used to work with his father and others, as they retired, he began working by himself. His brand name, Yoshimune, was founded in 1916.
Kawamura-san forges his knives by hand, beginning with a high performing shirogami #1 carbon steel core. The high carbon content of Shirogami #1 (1.3%), combined with Kawamura’s exceptional heat treatment, creates a cutting edge that is both exceptionally keen, and long lasting.
Making the knife easier to care for, the carbon steel core was forge welded between protective layers of stainless steel. While it is much easier to care for this knife than a full carbon steel knife, it still must be hand washed and dried to avoid rusting the core. We recommend using camellia oil to avoid rust and oxidation.
Kawamura-san is well known for his unique textured blade finish, which helps food release from the sides of the knife. This textured finish, known as tsuchime, is created by hammer-texturing the blade. The tsuchime created by Kawamura is particularly bold and elegant.
The premium octagonal handle is formed from macassar ebony (Diospyros celebica) with a black pakkawood ferrule. A stainless steel spacer adds nice contrast. This handle holds up extremely well in the harsh environment of the kitchen. Like other kitchen knives, this knife should not be put in a dishwasher.
Both the blade (which features a 50/50 grind) and octagonal handle are ambidextrous.
