SG2 is considered by many to be one of the finest blade steels in the world for kitchen knives, prized for a super-dense, pure grain structure that makes it both harder and less brittle than comparable steels. Kei Kobayashi chose it as his first offering when he moved from years of sharpening and finishing knives for other blacksmiths in Seki City into forging knives under his own name. The SG2 core in this gyuto is clad in a softer stainless Damascus jacket for added protection and easier sharpening.
This is a genuine laser in every sense - thin, light, and capable of falling through produce and proteins with very little resistance. The spine and choil are carefully rounded for comfortable use, and the rosewood octagonal handle with maple ferrule provides a comfortable, well-balanced grip even at this longer length.
What Customers Are Saying: Reviewers consistently describe this knife as a true laser, not a workhorse - thin enough that one reviewer put a couple of light bends in his blade during early use and cautions buyers to keep it away from bones or hard prying tasks, while emphasizing how effortlessly it falls through vegetables and clean proteins. Multiple reviewers note some food sticking to the blade, which they attribute to the slight matte finish on the Damascus combined with the thinness of the blade itself, though most still call the cutting feel superb and the handle beautiful. One owner who also has a Yoshimi Kato in HSS reports he is increasingly preferring the Kobayashi, noting the factory edge arrived very sharp and has only improved with light honing. Another calls it the most aesthetically beautiful knife in his collection, praising the pinch grip and skillful construction, while noting the balance point sits slightly forward given how light the blade is overall.
Care Instructions: SG2 is stainless and highly resistant to rust, but it is hard and somewhat chip-prone at this hardness level. Use wood or rubber cutting boards only. Avoid bones, frozen foods, and hard materials. Hand wash and dry after use - no dishwasher. Strop regularly between sharpenings and use quality water stones when a full sharpening is needed.

SG whoa!Posted By: Brendan R Moore

Maybe not your starters knife. This puppy is thin! I put a few nice bends in my Kobayashi the first time I used it! Ugh, I know horrid! This is a blade for focused work. If you might come across bone or other hard items I would not go to this blade. If you are slaying veg prep and cutting cleaned meats, this is an amazing blade. It absolutely falls through ingredients, the profile is one of my absolute favorites! If you're a rocker or used to classic French profiles this is yours. There is some sticking to the blade, I think this has to do with the slight matte finish, but also due to the thinness of this blade. The handle is beautiful and the feel of this knife is superb. If you're looking to get into lasers this is a great choice! Just be aware! Lasers are far different than your standard workhorse.

Great knife! Mine is in SG2 demascus and it works very well and came from the factory with a very sharp blade. Ran the steel across it after using it a few times and it has just gotten better and better. I also have a Kato Nikiri in HSS and it very good as well, but I am beginning to prefer the SG2.

Pros - Most awesomely beautiful knife I own. The sharpest knife I own. Wonderful pinch grip. Skillfully and aesthetically constructed.
Cons - Since knife is so light it balances in front of the pinch grip which encourages me to use the tip of the blade. That makes it great for fine work, but not so for mincing. Since blade is extremely thin, it sometimes catches on the cutting board. Since blade finish is matt, food sticks to it easily.
