The Cosmos santoku weighs 8.5 oz, a touch more than the series chef knife, on a shorter 7-inch blade: compact, yet with real heft in the hand. With a 1.8 mm spine, the thin blade moves easily through sweet potato, celery root or kabocha squash and cuts with a forward stroke. The ergonomic blue marbled resin handle, with a steel end cap and bolster, carries a gold mosaic pin.
Santoku means “three virtues” in Japanese: meat, fish and vegetables. The blade is shorter and flatter than a chef knife, with a dropped tip, so you cut with a forward push instead of a rocking motion. Very nimble, ideal if most of your prep is vegetables. Japanese-style blade, thin and hard.
Blade and Handle
The Cosmos Damascus Santoku Knife 7" has a blade made of 67 layers of damascus steel around a 10Cr15CoMoV steel core, hardened to 60 ± 2 HRC, thinner than most (1.8 mm at the spine). The ergonomic handle is blue epoxy resin swirled with white like a nebula, framed by a steel bolster and end cap and set with a gold mosaic pin. Every resin pour gives a different pattern.

Questions
Before you buy
What is a santoku knife used for?
Slicing, dicing and chopping vegetables, meat and fish. It is a versatile knife, more compact than a chef knife, with a flat blade that cuts in one forward stroke.
Why do some santoku knives have dimples?
Dimples reduce sticking with wet foods like potatoes. A smooth blade cuts just as well; slide the slice off with the flat of the blade.
Is the resin handle water resistant?
Yes: epoxy resin is waterproof and does not swell. Still, hand wash the knife and dry it right away, for the blade and the steel parts of the handle. Never 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.
