What is on the perfect Swiss Army Knife? To me the Tinker gets close, but it lacks the scissors, saw, and file. Add those and that begins to look like a Master Craftsman. But if you're going for that why not use the Plus scales that hold the pin and ballpoint as well as the tweezers and toothpick. That will require ordering the scales and the ballpoint, but that would address about everything I'd use a SAK for. The only problem is it is now a fat 5 layer SAK instead of my beloved svelte 3 layer Farmer.
