Canadian custom knife maker Lorien Arnold uses the forces of nature as inspiration for his impressive designs like the Boker Plus Undertow. The ball-bearing drop-point blade with a satin finish and ricasso starts where sharpness ends. From cutting up cardboard to small camping tasks, the pocket-knife is beyond reproach. Jimpings on the back of the blade, the pronounced flipper for opening the folder and the sturdy linerlock increase work safety, while the two-part handle with stainless steel bolsters with titanium finish and black G10 handle scales interpret energetic thunderclouds. The theme of water is taken up in a variety of ways by the revolverlike blade pivot screw and the handle screws, each of which is anodised in a deep blue. A pocket-sized force of nature, or to put it another way, The Undertow is in the flow. Only to be tamed by the tip-up clip (r) and the high-quality nylon case for storage.
