At 3.5 oz with a 5.5-inch blade, the Cobalt boning knife is easy to guide with precision. Use it to prep a chicken thigh for stuffing, trim a pork tenderloin or clean the sinew off a flank steak. The closer the blade stays to the bone, the less meat you lose. It does not replace the series cleaver, which deals with cartilage. On the handle, burl wood near the blade and honeycomb midnight blue resin at the butt.
A boning knife has a narrow, pointed blade that follows the bone closely. Use it to debone poultry, a leg of lamb or a shoulder, to trim sinew and fat, and to fillet fish. Japanese-style blade, thin and hard.
Blade and Handle
The Cobalt Damascus Boning Knife 5.5" has a blade made of 67 layers of damascus steel around a 10Cr15CoMoV steel core, hardened to 60 ± 2 HRC. The rippled pattern comes from the layering, so no two blades look the same. The round handle pairs burl wood near the blade with honeycomb-patterned midnight blue resin at the butt, finished with a stainless steel bolster and a black spacer. The wood grain changes from piece to piece.

Questions
Before you buy
Why a narrow blade for boning?
A narrow blade slips between bone and meat and follows the joints, so you lose less meat than with a wide knife.
Can it be used on fish?
Yes, for filleting. For very delicate fish, a more flexible fillet knife is more comfortable.
Is the resin and wood handle water resistant?
The resin is waterproof, but the burl is still wood: a quick rinse is fine, a long soak is not. Hand wash the knife, dry it right away, and never leave it in the sink or put it in the dishwasher.
Do I need to oil my Damascus knife?
You only need to oil a Damascus knife regularly if the blade is carbon steel or the handle is unfinished wood. A thin coat of food-safe mineral oil or camellia oil protects against moisture. Stainless Damascus needs oil only now and then, for storage. Avoid WD-40 and cooking oils that turn sticky on a kitchen knife.
Can Damascus knives go in the dishwasher?
No, Damascus knives should never go in the dishwasher. Heat, long exposure to moisture and harsh detergents dull the pattern, encourage rust and damage the handle. The blade also knocks against dishes and loses its edge. Hand-washing with warm soapy water and drying immediately takes under a minute and keeps the knife in shape.
Can you sharpen a Damascus knife?
Yes, you can sharpen a Damascus knife like any kitchen knife, ideally on a whetstone. A medium grit around 1000 rebuilds the edge and a finer stone polishes it. Japanese-style blades are usually sharpened at a lower angle than Western knives. Skip pull-through sharpeners, which are too harsh for hard steel, and use a ceramic honing rod between sessions.
Which Japanese-style knife should I buy first?
The best first Japanese-style knife is a chef knife (gyuto) or a santoku. Both slice, dice and chop meat, fish and vegetables, so one blade covers most daily cooking. Pick a gyuto if you like a longer blade and rocking cuts, a santoku if you prefer a shorter, lighter knife. Add a nakiri later if you cook a lot of vegetables.
