Don’t you just love lists? The kind that web sites or dead tree mags compile of the best this, the most interesting that. Yeah, it’s pure link bait. But it works! Which is how I found popularmechanics.com’s compendium of the seven knives everyone should own. There are a few obvious choices: the venerable Swiss Army Hiker, a Stanley utility knife and a Case Sod Buster. But a Masamoto VG gyotou? Is a machete a must-have? And while the Leatherman Rebar has a blade, it’s not a knife. Assuming that seven is the number – and I’m not so sure it is – what makes your list?
