Following the success of the original Green Goblin in M390, we asked Nguyên and his wife in Hanoi to create a second interpretation—one that would appeal to cooks and butchers who appreciate the unmatched sharpening experience and cutting feel of high-carbon steel.
The result is this Green Goblin Go-Mai, hand-forged around a 52100 high-carbon steel core wrapped in a striking five-layer (Go-Mai) construction. Known for its incredibly fine grain, 52100 has earned a legendary reputation among knife enthusiasts for taking an exceptionally keen edge with remarkable ease. While it won't match the extreme wear resistance of M390, it rewards the user with faster sharpening, a more responsive edge, and the satisfying cutting feel that only carbon steel can deliver.
Just like its M390 counterpart, this boning blade was intentionally designed with a stiff profile rather than a flexible one. The goal was maximum precision when trimming silver skin, separating muscles, removing fat, and making clean, controlled cuts. The rigid geometry offers outstanding accuracy and feedback, making it a true precision tool.
As with any premium high-hardness carbon steel blade, this is not designed for cutting through bones or twisting against hard materials. It is optimized for precision butchery, where its thin geometry and razor-sharp edge truly shine. Used as intended, it delivers effortless cutting performance and is incredibly easy to bring back to a screaming-sharp edge whenever needed.
Each blade is hand-forged, hand-ground, and hand-finished by Nguyên and his wife in Vietnam. Offered as a blade only, it allows the future owner to pair it with the handle of their choice, creating a truly personal custom knife.
