Konosuke is one of the most respected names in Japanese laser knives - a Sakai-based producer with a reputation for exceptional grind quality, precise fit and finish, and a consistent standard of performance that has made them a longtime favorite among serious collectors. The GS+ line is their upgraded version of the original GS: the same semi-stainless core steel ground to an even higher standard, with an HRC of 61-62 that pushes edge retention and sharpness beyond the original, smoother grinds on both sides of the blade, and a new Khii chestnut octagonal handle that updates the aesthetic while keeping the wa handle character the line is known for. The Tokyo-style machi gap between the handle and blade - a small, intentional space that alludes to the tsuba (hilt guard) on traditional Japanese swords - is an aesthetic detail unique to this line.
The GS+ petty at 142mm is the compact knife in the lineup, built for in-hand work on fruit and aromatics and for the detail cuts at the board that a larger knife cannot perform with precision. At 51g it is genuinely featherlight - one of the lightest petty knives we carry at any price point - and the 2mm spine keeps it nimble and responsive from heel to tip. The GS+ semi-stainless core is stain-resistant and low maintenance, with an edge performance that one reviewer describes as a razor that seems to stay that way, and another calls simply brilliant - comparing it favorably to the Konosuke HD line. The Khii chestnut octagonal handle has no ferrule, which is part of what keeps the weight so low, and fits the hand naturally for both in-hand and board work.
What Customers Are Saying: Two owners sum it up efficiently. One describes it as super light, very easy to use, and sharp as a razor - the kind of knife you get excited to pull out of the drawer. The second is even more direct: absolutely brilliant, and calls it just as good as the Konosuke HD, no need to wait for those to come back in stock.
Care Instructions: GS+ semi-stainless is low maintenance and resistant to staining. Hand wash and dry after use - no dishwasher. Sharpen on quality water stones when the edge needs attention and maintain with a strop or ceramic rod between full sharpenings.

Excellent little knifePosted By: Joel - verified customer

This knife is very handy for small tasks and seems to stay sharp as a razor. Its super light and very easy to use. I'm not a chef but love to work in the kitchen so I don't have much to compare this to other than how excited I get when I can pull it out of the drawer. Hope this helps.
