The P-38 and P-51 Multi Tool Combo
The P-38 Multi Tool Use and History
This 1.5-inch tool was designed to open C-Rations during WWII. The "P" may stand for puncture and "38" for the number of cuts it took to go around the can. The hole in the P-38 was used to dip it in boiling water to sterilize after use. Developed in only 30 days by Chicago’s Subsistence Research Lab, it is considered by some the most perfect tool ever designed for combat. It is often called "the Army's Best Invention."
The P-51 Multi Tool Use and History
The P-38's big brother, the P-51 was introduced in the 1960s. Measuring 2-inches long, the P-51's greater leverage makes it a faster can opener than the P-38.
