I keep a P-38 on my keyring. I've never used it while backpacking...as I don't bring cans. Car camping, yes, but not lately.
Over the last 2 years I've probably used it twice. Once to open a can and once to cut some sting(mine is sharpened). More and more cans are coming with pull-off lids that don't require openers.
Death of the p-38?
