Rockstead SAI T-ZDP (DP) Folding Knife 80mm


Since its inception over 70 years ago, Rockstead Knives have been producing unique and extremely high performing fixed and folding knives. Rockstead specializes in unorthodox manual machining practices and modern materials to output knives that create a league of their own.

The blade of the T-SAI is as functional and robust as it is magnificent. The mirror-polished blade features a symmetrically convexed zero-grind, referred to as “Tanto - Honzukuri”. This provides both a robust and fine edge, suitable for most daily cutting tasks. ~66 HRC hardened ZDP-189 steel is sharpened and polished perfectly to be razor sharp for years to come.

The robust feel of the blade is matched in the handles. Hidden hardware allows for the seamless faux-integral construction to feel solid, and comfortable in use. The milled titanium pattern and intricacies are intriguing to examine, and provide for more grip in all directions. We rumour the handle milling is designed to resemble topographic lines on a map.

The T-SAI can take any folding knife collection to the next level. Built for purpose, this knife is built to be carried, and used, but will feel just as at home on a display shelf. We implore any collector to use this knife wherever comfortable, to have the true Rockstead user experience.

Rockstead knives can be registered online to access their lifetime warranty, and free sharpening programs. Rockstead suggests using their sharpening program exclusively.
