On a totally different note regarding the can openers.
I recently needed to remove a company logo that had been stitched onto a work jacket from a place I used to work for. The jacket in question is one of the superb "snicker" brand items - fantastic quality, but very expensive. The jacket was part of the annual issued uniform upgrades - but never actually saw any use as the old one I was wearing was still okay.
I then left and took it with me
The wenger can opener was truly faultless as a "picker" probably better than commercially availble pickers. My partner has since used it many times to let down the hem on my ever growing young sons trousers.
It's simply brilliant - Tried the victorinox version, nowhere near as good.
So, another use for the SAK.
Incidently, much is often spoken of what is the purpose of the backside hook on the vic's - I used mine a few weeks ago to lace up tight my nieces rollerboots - worked a treat!!
