Generally speaking, every man should own at least one pen knife, whether it gets used or not, it’s the kind of thing you just have to have even if it’s just to say you do. This collaborative offering between Vivienne Westwood and Victorinox sways towards the latter: those who have these things but never use them. Finished in green imitation Rhodium, this stylishly crafted pen knife features the Victorinox classics — blade, nail file, tweezers, toothpick, keyring — and a Vivienne Westwood orb charm. Seeing as it is suggested to retail at around $424 US, you’d have all the reason in the world not to want to use this knife.
