The WOHO WOkit 2.0 is a lightweight carabiner that incorporates practically all of the tools you’ll need to tweak your bicycle, and then some. It has hex, Torx, flat screwdriver and Philips screwdriver bits, a chain rivet extractor, nine wrench sockets and a bottle opener.
There are plenty of carabiner clips on the market, but none as impressive looking as the Gatekeeper. It’s made from anodized aluminum, clad with titanium, and stainless steel hardware. It’s not for climbing, but it’ll do a bang-up job holding your gear and keychains.
