EXTRAMARISE EXTRAMARISE® is a proprietary heat treatment ideally suited for haircutting scissors that was developed by MIZUTANI based on long years of accumulated data and experience. The same steel material can have totally different performance depending on the heat treatment used. Therefore, to maximize the special qualities of the rare metals (cobalt, molybdenum, vanadium, etc.) we’ve added to our products to the greatest extent possible, and achieve the ideal metal for scissors, (*hardening, tempering, sub-zero processing) and other complete temperature management procedures are essential. To bring out the distinct characteristics of materials, and manufacture a blade with the ultimate strength required for haircutting scissors, we at MIZUTANI have implemented our own proprietary heat treatment using the ideal temperature for scissors: EXTRAMARISE® processing.
