The famous rolling thumber, but in key pinch fashion! Yes, it could also act as a regular thumber for baby hands.
Inspired by Jaland Worley's passion (and world class strength) for key pinches and the rolling thumber, this combines the best of both worlds.
Available in 3 roller diameters (1", 1.25" and 1.5") to diversify your key pinch training. Please note that each of these variations come as their own implement. This is because the axle for the different diameter rollers sit at different distances from the base plate in order to maintain a minimal gap between the base plate and their respective roller.
The 1" diameter is recommended if you're keen on training for the inch pinch.
By default, the finish on the rollers are kept to raw steel to support consistency in competitions and also to allow for natural seasoning.
