One of our newest additions to our growing line of value butterfly knives is the Revolution Butterfly Knife. This all black knife sports a spear point blade with a small groove down the middle of the blade. The blade is sharp on one edge and has great action. If you prefer faster or slower movement, you can adjust the blade tension with the torx screws in the handle. The handle has a unique shape that is somewhat squared off. I like the look, but even better, I like the feel of these handles. They are easy to hold onto. The weight on this butterfly is mid to heavy and the action is top notch. This is a great butterfly knife.
