Inspected and Certified by our internal laboratorySHIN in Japanese means ‘trust’.
The SHIN is one of the largest folders in the Rockstead catalog and showcases all the typical and characteristic elements of the brand: aluminum handle with a pearl-radiant design, hardened anodization at 400 Vickers, and an insert of high-quality stingray leather (Samekawa).
This is a durable knife with strong cutting capabilities that maintains its edge for a long time. Even when used for rigorous cuts, the blade glides securely thanks to its particular sharpening.
The blade indeed has a HONZUKURI sharpening, convex on both sides, following the tradition of Japanese swords; this makes it both very sharp and sturdy, allowing it to cleanly cut a sheet of paper even after 1000 cuts through a very abrasive and resistant hemp rope.
A faithful companion for life, in which to place the utmost trust.
