Ohayo from my simple home. I have visited your Beautiful mountains in Gunma. BK2 is lifetime tool. Your skill is very impressive. Where i live are many black bears and packs of wild pig and coyotes. The need to remove a knife from the sheath while under attack is my first concern. Also carying it over one shoulder and around the neck where knife is at mid chest level is important because wnen under attack from bear or pack of dogs you must protect your stomach from attack. Also this makes finding knife while protecting your organs possible. Thank you for inspiring so many people to realise such high quality work is possible.
