The Shun Sora series uses proprietary composite blade technology bringing together a VG10 san mai cutting edge with a Japanese 420J stainless steel blade. The two blade sections are laser cut and fit together like pieces of a puzzle, and the braze welding permanently joins them together. The wavy pattern at the joint is based on traditional Japanese sword hamon lines. The textured PP/TPE polymer blend handle material provides a contemporary look, secure grip, while easy to maintain. The debossed stainless steel logo enhances and balances the handle. Handcrafted in Seki City, Japan, 10-year warranty.
