Overview

Rockstead produced the original NEHAN from 2007 to 2010 and decided that 2017 was the right time to do an updated version of this model. It was designed by Koji Hara, a very famous custom knifemaker known the world over, and it's a very true, classic representation of the original piece. However, all the materials are totally different making this NEHAN a more high-end, hard use tool than the original.

The NEHAN is a perfect example of Japanese styling, craftsmanship, and attention to detail. This is one of the highest quality folding knives available in the world with Rockstead's expertise cultivated through years of experience. The blade is ZDP-189 steel with their traditional mirror polished finish and locks up with a button lock mechanism. There are two different handle material options with the NEHAN; both are durable and feature the exact same milling pattern. The MB is "Artificial Marble", used in high-end kitchen countertops while the ER is "Ebonite", used in high-end fountain pens. These materials are fixed to titanium liners to give the knife strength and durability throughout. The simultaneous precision finishing of the handle manufacturing process allows Rockstead to construct the knife without visible screws which keeps the clean look of this design, meant to look like the fold of a Japanese Kimono. Feels extremely comfortable and solid in the hand. Individually numbered.

With proper maintenance, Rocksteads are known to keep a sharp edge for 2-3 years. Rockstead Knives come with free sharpening and regrinding. You would be responsible for shipping charges to and from Japan.

Hara, Koji

A native of Japan, Koji Hara was born in 1949 in Imari City, and is one of the most traveled of Japanese knifemakers, attending shows throughout his home country as well as over the United States and Europe. When he began making his first knives in 1988, they were his versions of Bob Loveless designs. Three years later he held a one-man knife show in Seki City, Japan, heart of the production cutlery industry. It was at this point in his career that he realized he had to make and sell knives of his own concept and design if he was going to succeed. In 1994 Koji had become a Probationary Member of the American Knifemakers Guild, and in 1997 a Voting Member. During this period he was participating in at least five American shows per year, and would soon be attending shows in Europe. Annually, this prolific maker attends two knife shows in Japan, in addition to having maybe two one-man shows, usually in smaller communities, where collectors don't visit the larger cities. He feels these small shows enable more and more people to become familiar with custom knives. He has received awards for his folders such as "Best in Show" and "Most Innovative" in several international knife shows. Koji primarily uses a powdered stainless steel known as Cowry-Y, made by Daido Steel in Japan, for his blades. It holds an excellent cutting edge and polishes to a high mirror finish. Although one of the drawbacks of powdered steel is its weakness towards lateral impact, this can be corrected through proper heat-treating. Koji also makes knives featuring ATS-34, D-2, 440C and other steel blades, based on customer preference. His preferred method of making blades is via stock removal. A folder specialist, he often carves the handle material into a terraced landscape to feature his classic "Air-Step" design.
