Key keepers for hand tools

myminifactory

This is an example of "keepers" for tools or wrenches that are required for use of a power tool. The first is for an allen key/ allen wrench that is needed to change the tool head on an oscillating multitool. The second is for the common spanner wrench used to loosen the nut on an angle grinder. If these wrenches go missing you're out of luck until you go find another one, so this keeps them at hand by attaching them to the end of the electrical cord.   It is deliberately a tight fit; the wrench should stay in and stay down at the plug end so that you have to unplug the tool to change the tool head. This is how you keep all your fingers intact. For the spanner holder, you have to fold the wrench keeper in half with pliers and stuff it through the loop while wrapping it around the cord. As with the allen wrench keeper, it's a deliberately tight fit.
