I do remember Leatherman stickers with a text that sounded like that... But no SAK ones.
I suggest you to ask the main Victorinox dealer in your country.For example, here in Zagreb, Croatia, our main Croatian Victorinox dealer has some Victorinox stickers that can be purchased, for about 1-2$ each, depending on the size, I think...
Victorinox has various promotional materials (stickers, umbrellas, posters, postcards, leaflets, etc.), you just have to find the dealer who sells it.EDIT: This is a link to their catalogue, you can see the stickers on the page 57:http://www.victorinox.com/medias/sys_master/swissarmyknives/8805009391646/Catalogue_english.pdf
