Bear & Son 5" Butterfly Knife

Notify Me When Available

Bear and Sons make great butterfly knives.  Their butterfly knives have pin construction which has some advantatges and some drawbacks.  The biggest advantage of pin construction is that the butterfly knife should never have to be adjusted.  If they are made correctly, this style of butterfly knife is great to use for both beginners and experts.  Bear and Sons does them right.  The drawback is that the tension on the blade is not adjustable.  If you get the knife and the action is too fast or too slow–there really isn’t a lot you can do to change it.  But, with that in mind, I think the Bear and Sons model BC117B is made right.  It has a nice tanto style blade point with the blade made of High Carbon steel.  The handle is epoxy coat powder cast metal.  Nicely made with quality materials, the BC117B is a fantastic butterfly knife.
