20-in-1 STAINLESS STEEL MULTI-TOOL Our 20-in-1 Stainless Multi-tool was originally designed to be a snowboarding multi-tool, however, we found that it is useful to carry the prototypes around on our key chains, in our pockets, and attached to our backpacks, but the usages of this tool is so much more than these. You can also use it to open the beer bottle, turn the screw, fix snowboarding,and bicycle, open carton box and so on
