After reading Andy Champ's Q about "tool of the year" for 2013, I wondered, with the benefit of hindsight, what was the best tool acquired in 2012?
I am actually rather taken by my recently bought Bessey foldable utility knife. Got mine much cheaper and without wallet from a local shop but this links shows one:
Also very quick and easy to change blades without even a coin to unscrew.
On the downside, some of the edges are a little harsh on fingers when in pocket. Nothing awful but could have been designed and made to be more rounded.
