Fire in the hole!

The rounded ball shape creates a demanding open-hand grip, forcing the fingers and forearms to work harder than they would with a conventional handle. This makes them ideal for grip strength

Grenade 80mm
This thing is wicked for training lumbricals/intrinsic hand muscles for climbing. Perfect for getting flex in dip joint.
