The Shun Sora Paring 3.5" Knife is part of the exciting Shun Sora line that provides exceptional handcrafted Shun quality at an amazing price. Sora uses Shun's proprietary Composite Blade technology to bring together a VG10 san mai cutting edge with a Japanese 420J stainless steel upper. This technology puts high-performance material exactly where it's needed—on the edge. The two blade sections are laser cut, then fit together like pieces of a jigsaw puzzle. Braze welding permanently joins them. The attractive wavy pattern at the joint is based on traditional Japanese sword hamon lines. While Sora's blade shapes and handle design are traditional Japanese, the textured PP/TPE polymer blend handle material provides a contemporary look, secure grip and balance, and is easy to maintain. Keep your Shun Sora 3.5" Paring Knife sharp and well maintained with a Combination Whetstone , Leveling Stone , and Knife Care Kit .
