Rockstead REN-ZDP folding knife has a unique design where the handle's Western geometrical contour and pattern are perfectly combined with the traditional Japanese Katana geometry blade "Tanto - Honzukuri."
It is well known that all Rockstead-made knife names and terms used by Rockstead have special hidden meanings, and Ren is not an exception.

The name "Ren" (錬) - comes from classic honorary titles in Japanese Martial arts (Budo): Ren-shi, Kyo-shi; Han-si; Mei-jin. These names were conceived as signs that a certain level of skill and understanding had been achieved. They are awarded only to those who "have a certain rank and are distinguished by the exceptional technique, knowledge, and character of Japanese Martial arts." Applied to the REN model, Rockstead shows that it is just the first level on the way to perfection.
Honzukuri (本造り)  is a term that came from Japanese traditional Katana craftsmanship, which means "Examine the raw materials and ingredients, and take the time to make the Katana properly." 

HIGH-END STEEL ZDP-189 + BEST HEAT TREATMENT (67 Hrc) + PROPER CONVEX BLADE GEOMETRY WITH A VARIABLE ANGLE ALONG THE ENTIRE LENGTH + HIGH-END MIRROR POLISH + MIND-BLOWING SHARPNESS = ROCKSTEAD REN HONZUKURI. Simple formula )))

The REN has an impressive handle with 3D milled dry carbon fiber scale on the presentation side, a 3D milled Titanium Frame Lock with Hardened Steel Lockbar Insert on the other side, and a perfect,  smooth action through phosphor-bronze washers and high precision fitting.
Also, please note that there is a unique number milled on each blade, so you can register your knife on the Rockstead website to prevent reselling it in case of stolen.
Each REN is packed into a Paulownia wood box with an individual knife passport and warranty letter.
(Note) REN is not a flipper knife model.
