Give your thumbs a blast with these spherical key pinches!
Keeping your thumb straight will provide an added challenge, especially for those whose thumb doesn't bend down far beyond the joint. Alternatively, you can have the thumb on an angle, which may make it easier due to having more hook under the sphere.
The 40 mm variant is a great way to train for the Finnish ball armlifting event!
By default, the finish on the spheres are kept to raw steel to support consistency in competitions and also to allow for natural seasoning.
