For larger hands maybe this Tone is more suitable. The handle is 22 mm longer than that of ko-ken.

I have that Tone driver handle, and it is a nicely made tool. Small, but you can still get a good grip on it.
Even though this may be the "Tools of Japan" thread, the Stahlwille 400QR is also a very nice 1/4" driver handle. It doesn't have the handy square drive hole at the end of the handle, but it does at least have a hole in the handle to stick a screwdriver through for more leverage. It also has a push button locking tip, which I think is a great feature.

For 3/8" drive, it's hard to beat the VIM HD375 driver handles / extension bars IMO. Nice and solid, pull-back locking collar, and a square drive hole in the end of the handle.

I guess we are restricting ourselves to talking about driver handles that also work as extension bars (or at least driver handles that have some other means of increasing torque, like the Stahlwille). So it's probably okay to include this Straight 3/8" wobble driver handle that bends in the middle.

If we were to expand the discussion to include all types of driver handles, there would be many, many more choices.
