As the title goes..... Not sure about IKBS, for me you can see the balls looking down the blade when folded. Therefore surely if used, its much more likely to get clogged up with whatever you are cutting. therefore messing up the movement. And knowing how clumsy I am, stripping it down would probably mean losing balls all over the place. I've got factory made Bucks with a bronze bushing that seem to work just as fast and slick. I wouldn't have a fear of either using it or, stripping it down. I believe that you can get ceramic ball race IKBS, that will cut out the rusting but you've still got the other issues, i've mentioned.
What am I missing here! do you think IKBS is an improvement or, a gimmick. Maybe its for collectable knives only, that are not for general use?
Educate me on IKBS please.
