While Michael Walker did not invent the liner-lock, he certainly is the reason it is today one of the most popular blade locks in our industy. This Michael Walker design made by H.P. Klotzli Knives was, from what I can tell from our records originally offered in the early 1990's. While most knifemakers, specialty knife people or huge factories do not give Michael credit for this popularization, H.P. Klotzli always has. For a number of years, he has produced this Walker design with various handle materials. The most popular has been with carbon fiber. The 2-3/4" clip point blade is ATS-34 stainless at 59-61 Rc. with a very nice satin finish. Includes a black Napa leather pouch and a nice gift box. Measures 3-5/8" closed. Weighs 1.6 oz. Made in Switzerland.
