I'd suggest a Juice model from Leatherman:XE6C2 and S2Kf4These are about the smallest tools you'll find with a decent array of features and full sized dedicated pliers. I would also suggest the SOG CrossGrip because it has really nice pliers, but the rest of the options are a little lacking.The Victorinox Spirit is also a great balance of size, weight, function and price.Def
I feel the Juice models are a little too expensive (unless someone knows of a place selling them cheap in the UK). To put things in perspective, I'm getting a Swisstool X for about £40. Fantastic, but I think it's a bit too big for EDC. I can get the Spirit for slightly more than that, but what's the size difference like (is it worth getting both, or are they more or less the same size)? The CrossGrip and Blast look OK and seem to have fair price tags, but does anyone know what the size difference is? The Blast would cost about £20 more than the SOG, but if it's the same size(ish) I wouldn't mind shelling out the extra for the better tool selection.
I'll agree with the KF4 as well. I'm not a Gerber expert, but if you're looking for a smaller price tag, they seem to make a good tool for the money. But I think they're a bit bigger than a SAK.Welcome to the forum by the way!
