Probably the best of its kind
At about 58mm length, this opener is a little longer than the usual P38 or P51 openers, and is possibly why it works so well. I don't think I've used one as easy as this, and for the price, you'd be mad -if you carry canned food on your hikes- not to have one of these in your kit as a back up, in case your usual can opener breaks or the tab on your pull-tin snaps off.
I know people don't use canned food so much in these days of laminated pouches, but these things are so small and light, it's worth carrying one just in case you come across a can at some stage while away from home.
It is so good I don't bother packing a regular opener now, I carry at least two of these with me, they are so small as compared to any other opener. Even tough hardy cans can be opened using a glove for more grip and leverage.
I permanently have one of these attached to my keyring too - just put a bit of twin-stick tape under the cutter to stop it inadvertently opening in my pocket.
As a nice touch these also have a bottle opener cutaway too!
