An Engineer in Wonderland – The best tin opener?

p38add.jpgOne of the neatest designs I have ever come across is the military folding tin opener.

I am talking about the little rectangular ones with a hinged tooth, sometimes known as P-38s.
For a few grammes of steel, you get something that opens food containers in under 10s, and is far less dangerous than the ram-in-and-chew-your-way-around portable type that leaves a nasty sharp edge on the container.

And much easier to use than the attachment on a Swiss Army Knife.

The only disadvantage I have ever come across is the tooth can unfold in transit and poke holes in things or scratch them.

I believe it is a US design and would love to know who invented them.
