Mikisyo Blue #2 Kogatana 65mm. This hand-made kogatana uses high carbon steel. This handy knife is used for whittling or other uses and it comes with a really nice saya that allows you to safely take it on the road to work, cooking school or into the field. Mikysio, a specialist in kogatanas, is based in Miki City which is located on the western side of the mountains that separate Kobe city from the interior of Japan. For over 100 years, many blacksmiths in Miki City have made these small knives. Many customers use these as petty knives in the kitchen but they also work well for grafting, whittling and paper cutting as well as box cutters.
