The 240mm is where the GS+ line finds its fullest expression. More blade length amplifies everything the 2mm spine and GS+ semi-stainless grind deliver at 210mm - longer, more efficient strokes through proteins and larger produce, better reach for high-volume prep, and a laser-geometry feel that becomes more pronounced as the blade length increases. Konosuke produces this in Sakai at 61-62 HRC, with smoother grinds and better fit and finish than the original GS, and the same Khii chestnut octagonal handle and Tokyo-style machi gap that define the updated line. The machi gap - the small intentional space between the handle and the blade at the choil - is a detail borrowed from traditional Japanese sword design, where the gap accommodated the tsuba (hilt guard). Here it is mostly aesthetic, but it also places the balance point precisely at the pinch grip.
At 236mm blade length and 128g with 50mm blade height and a 2mm spine, this is a substantial gyuto (Japan's all-purpose chef knife) that performs light. Cooks who own both the 210mm and 240mm consistently describe the edge retention and balance as matching across both sizes - which reflects the consistency of Konosuke's production standard rather than any compromise in moving to a longer blade. The GS+ semi-stainless core is stain-resistant and low maintenance, sharpens readily on quality water stones, and responds well to a leather strop between full sharpenings. The Khii chestnut handle fits comfortably in a pinch grip through extended sessions. Trust the photos over the video, which shows an older handle version.
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.
