About the P-38. More than just a can opener...
I've used mine to open beer bottles. Very useful skill, esp. on Western trails where there are more microbrews. :-)
My oldest, still being used gear, is not all that old to be honest. It is generic circa 1996 day pack I bought from Sportsman Guide for $25 that same year.
I can't believe how well it has held up for the price. Now, it has salt/sweat stains, ground in red dirt from canyon country, is faded from the sun, has to been to Mt. Washington in the winter, etc. etc. I use it almost every day and it shows! (Also carries my books, coffee mug, etc.Lots of coffee stains, too ) The stress points are restitched with dental floss.
So, it is only 11 yrs old..but it has had a charmed life!

(Yep..those are trail patches. Up until 1 month ago, I hadn't owed a car in 6 years! The patches are my "wicked cool bumpah stickahs"!)
