What’s the difference? The P 38 and the P 51 are both the same except for their size. They’re both small, but cleverly designed to easily open a can. The P 38 can opener measures 38mm long (~ 1.5 inches). The P 51 can opener measures 51mm long (~ 2 inches). The handle portion will also double as a flat-blade screwdriver.

If you are looking for a small, lightweight, and cheap can opener, then the P38 is the better choice. If you are looking for a larger and heavier can opener that is still very lightweight and cheap, then the P51 is the better choice. Both are good quality and very durable, so it really comes down to personal preference.

The P-51 can opener is a larger version of the original P-38 can opener. Developed in 1942, the P-38 was developed in 1942 and was issued to military soldiers along with their canned field rations and is about a half an inch smaller than the P-51. The P-38 and P-51 gained popularity due to its' multiple functions and is still in production today.
