The brand new Mako Bottle Opener V4.5 is our latest revision to one of our best selling products. In this updated design, the gills on the handles have been moved towards the zen pin area for increased comfort and grip while flipping. The size of the gills have also been reduced, allowing for more material in the channel which significantly increases the durability of the handles. The new handles are designed to preserve the iconic Mako look and is also strategically machined to maintain the same excellent balance.
The Mako Bottle Opener V4.5 is the perfect balance between flipping performance, durability, and utility. Machined from 6061 T6511 aircraft-grade aluminum, this trainer doubles as a top tier flipper and bottle opener. If you’re looking for a great budget flipper and a useful EDC tool, then the Mako Bottle Opener is for you.

Light Handle Bias
The Mako V4.5's primary dorsal fin is housed within the handles. Due to normal wear and tear, the fin may contact the inside of the handles. This is a normal effect that will prolong the handle gap of the Mako.
