You could . . . for something a bit more traditional, retro, what have you . . . go with a Buck Knight 505. One of my original EDCs I carried for years way back in the day. Seems to still be available new. Buck shows it on their web page.
There is something about going into an old local hardware store and buying a knife like this out of the tall skinny display . . . Kind of an EVENT you know ? I miss that !
The blade is a bit smaller than stock due to the fact that I arced it while cleaning a battery post for a damsel in distress to get her car to start. Put a nice divot in the edge that I had to later grind out. Yes that was dumb . . . I was a bit distracted by said beauty. I have since become much more immune to their venom with repeated bites over the years but those first few take a toll . . .
Knives . . .
yes . . . ahhhhhh . . . top one (for size comparison) Dragonfly, then Cold Steel Tuff Lite Mini (alas not made any more) and finally the Buck.
Very nice knife. I learned to pinch it in my pocket to partly open it (very easy to do) then hook the handle on the edge of my pocket and it would open as it came out of my pocket. The wave before the wave.
Can close it one handed by pushing lock release with thumb and wiping the back of the blade on your leg. Becomes second nature.
It's really decent in the hand and Buck tuff; no problem there.
Oh and it may be a bit bigger but the knife that I am really excited about for opening packaging and some specific uses I have it for is the Spyderco Cricket. I don't know about tuff but it is fantastic and a unique innovative knife. Slays those tuff plastic product packages without raising an eye brow.
A great companion to a large knife
