Sanj\u014d factory)<\/p>\n\n\n\n<p>Iwasaki is one of the most appreciated among collectors and traditional shaving enthusiasts for the quality of its steel hardening and workmanship. The razor was made in the Showa period, around the 1950s. It has a length of 16 cm, a cutting edge length of 5 cm and a weight of 35 g. It is a medium-sized, light-weight kamisori.<\/p>\n\n\n\n<p>Similar to a traditional samurai sword, this Kamisori was hand-forged from 2 layers, the cutting part made from high carbon steel and the support from a simpler, higher iron steel. What makes this Kamisori special is that the blade is forged from real Tamahagane. Tamahagane is a traditional steel produced in Japan several centuries ago. Because Japan does not have large iron ore resources, the steel is made by hand from iron sand in a process that takes several days. It was the main source of all samurai sword blades. The steel layer is brittle and hard, while the softer frame provides the necessary flexibility.<\/p>\n\n\n\n<p>Both layers are non-rusting, so always keep your razor dry after shaving and protect it with a thin layer of oil. Why is this razor stainless? The stainless blade is made from an alloy that will reduce the chance of corrosion spots, but also make it less hard. High carbon steel like this Kamisori cutting layer has a much higher hardness and will maintain a smooth shave much longer before you need to re-sharpen, especially this Tamahagane layer!<\/p>\n\n\n\n<p>Tamahagane \u7389\u92fc steel, a legendary and revered material in traditional Japanese sword making, holds a special place in the hearts of artisans and enthusiasts alike. Known for its exceptional quality and meticulous creation process, Tamahagane steel embodies the perfect combination of artistry, tradition and functionality. <\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<ul>\n<li>The blade material is forged Tamahagane steel hardened to a very hard 70 HRC, which means it retains its sharpness for a long time.<\/li>\n<li>Used, sharpened, but may need to be refinished and corners rounded.\u00a0<\/li>\n<li>No packaging.<\/li>\n<li>Blade dimensions: 45x16x2 mm<\/li>\n<li>Handle material: forged steel<\/li>\n<li>Overall length: 143 mm<\/li>\n<li>\u5ddd\u5d0e\u88fd\u4f5c\u6240 (Kawasaki Seisakusho) was a division of the Iwasaki workshop, where production took place in the later period, when Shigeyoshi Iwasaki no longer forged each knife individually.<\/li>\n<li>Mizuochi-san (\u6c34\u843d\u6c0f), a blacksmith, was a pupil of Shigeyoshi Iwasaki and worked under the supervision of, or under the direction of Shigeyoshi.<\/li>\n<li>Production period: 1975-1985<\/li>\n<li>Weight 21 g<\/li>\n<li>Origin: Japan<\/li>\n<li>There are traces of time and rust.
