These grips can be used
in two ways, as pictured. Two adjustable "knuckle
pads" hold the hand either across the back and knuckles, as shown in one
photo, or on each side of the wrist, like the tri-pin type of car steering
wheel device. For other custom applications, the grip can be used with one,
both, or neither knuckle pad.
To use these grips, just initially adjust the knuckle pads
to fit your hands. Then slip your hands into the open end of each grip and
start cranking away whenever you wish. It's just that easy. Not recommended
for a complete lack of grasp with straight fingers.
