Bear & Son makes some really nice butterfly knives. The BC117B is no exception to this rule. This butterfly knife is 9" when fully open and has that smooth solid action that you expect from Bear & Son knives. The knife is made with pin construction so you don't have to bother with adjusting tension and making sure everything is tight every time you get the butterfly out for some practice. The die cast metal handles are solid and easy to hold on to. Great butterfly knife.
