I've got a flip shank screwdriver with that mark on it and I assumed it was from a Lexus tool kit.
Lexus issues a tool kit? I'd be surprised - their target demographic is unlikely to be doing field repairs.
Around here Lexus seams to be fairly popular with the youngins to race around town with. But I don't think a factory tool kit would do much good after they get done with them.
I have learned that my Subaru screwdriver was made by Clover Mfg. Co. LTD. They also made other hand tools, namely, saws, hammers, spanners, nail pullers, nippers, pincers and scoops; hoes along with a host of other things mainly for sewing. I've not been able to confirm that they made the wrench wvtools posted but its a possibility.
