Never be caught empty handed when the need for either a 3/32" or a 1/16" hex-shaped allen key next arises. Yours is somewhere, we're sure. Somewhere under the workbench, or somewhere inside your dust collection bin, or somewhere inside your dryer's lint trap because you stuck it in your pocket and forgot just before doing the laundry. Why waste time hunting for one of yours when you could just pick up one of ours?
