I assumed it was a sliding t-handle. That's exactly what it would be for if I bought one, to go in the truck. But I couldn't justify spending money on a nice tool to just sit in the truck &
rarely never get used.
I've had my truck for 19 yrs now, not once have I ever got a flat & needed to change the wheel on the side of the road on it. Whenever I go on long trips I bring my M18 impact with me.
I used to carry my trusty Matco 1/2 breaker bar in the truck. But again, for the same reason above, I finally decided to move it's home to my home tool box. Last year I bought a cheap extendable breaker bar to take it's place in the truck which will probably never get used. Lol
I do have the Koken 3/8" drive spinner t-handle which is very nice. It's somewhat similar to Koken lug wrench so I have no doubt the lug wrench is the same great quality. It's the only Koken tool I currently own. I really wanted to get a Koken ratchet or two but once I found out they have backwards direction levers I can't own one.
