In the same way that their Tool Pens cycle through bits, Mininch’s WRENCHit cycles through interchangeable wrenches. The slim tool is made up of a SUS 420 stainless steel sleeve that holds up to five wrenches, each made of the same metal and engraved with their size and spec. To cycle through, pull out the bit in the tail end and push it smoothly into the front, in turn pushing the other four bits down a little. The ten available bits cover 15 functions, with one dedicated bottle opening bit as well as two allen wrench-equipped ones that also sport five spoke wrenches between them. Each also includes a pouch to stash and carry the tool along with all your extra bits.
