The OSS or Office of Strategic Services created the T-13 Grendade in WWII. The T-13 is an extremely rare grenade as all models were suposedd to be destroyed after the war. The T-13 was designed like a baseball since every
American male should be able to corectly hold and throw a baseball. This model of the T-13 is slightly diffrend than the real T-13 as the pin can be seen from the top and the top had a bumpy texture to it.
