Durable workhorses handmade in America by small businesses. Standard Grippers have been carefully crafted to fill hard-to-find gaps in your training set. Simple oil-tempered springs and aluminum handles with aggressive knurling. Everything you need and nothing else. Standard Grippers are named after increasingly hard metals and each gripper is stamped with the respective chemical symbol. The choices range from Tin at the bottom, which is more soft and malleable but has endless utility to shape your training, to Tungsten at the top, which is such a hard metal it's virtually indestructible.
