The rotational resistance is adjustable for fine-tuning your work.Heavy duty construction guarantees years of dependable service. It weighs 25% more than other blocks of comparable size.

All the parts have some surface spots and scratches from previous owner.
This is an older version with extremely precise milling for center shaft that goes into the base portion of the ball. I used the ball vice solely for wood engraving small boxwood blocks. This will last you a life time if you don't drop it and keep it covered when not in use. The ball is in two sections (2 parts).The two vice ends and center thread that simply sits in a groove are (3 parts). A ball bearing drops to bottom of hole, a plastic plug, spring and threaded hex screw adjust the tension on the center shaft inside the ball are (4 parts).
