I bought this tool for a compact circular saw. The T-handle is comfortable and fits my hand very well. Also, the T-handle helps me safely loosen/tighten the knot that holds the blade to the saw. The power cord has a rubber mount for a 5mm Allen key, so I never have a proper tool to change blades, secure the guide bar, etc. (all screws to change blades, etc. require a 5mm Allen key). I have yet to use a short hex wrench that protrudes from one end of a T-handle, but I can see how it can be very handy in certain circumstances. Given the low price and high quality of this tool, I have no problem buying it for one-time use and dedicating it to the saw by attaching it to the electric handle. I recommend this remedy unreservedly.
