What SAK do I carry or what is best for my regular carry?
I started out carrying a regular Tinker and loved that one. Used it for years. I like the basic tool selection.
Then got a alox Soldier which is the same size. Liked it but missed the tweezers and toothpick. Never was a scissors person with a sak. This is back when I probably owned just a few knives and was not into trying stuff out. I just used what worked.
Tried the 111 mm Adventurer (side lock model) and liked it even though it feels significantly larger in the pocket. I found this one at a gun show when I was in the market for another Tinker or tinker-like model back in the mid to late 90's. Really like this knife for using. The basic tools are there if I need something in a pinch.
More recently I have been trying to carry a large GEC traditional in a pocket slip, but miss the basic tools of the SAK. So, I carry a Bantam along with the traditional for the "other stuff" and it has a reasonable blade on it too. Now I am trying out a small stockman (3.3" closed) with the 111 mm SAK or a modern like a Delica or ZT. The large SAK does 95% of the cutting I do very well, so it is a matter of deciding what I like more now.
Most recently picked up a alox Pioneer. Nice knife, but if I am carrying a sak, I want the tweezers and toothpick available. To be honest, the Bantam or the little stockman would handle 90% of the cutting I do and I wouldn't even notice it in my pocket. But I tend to like about a 3" cutting blade so I flip around with the GEC traditional, various moderns, and sometimes the small stockman.
If I am thinking about it, I'll take a one-handed Trekker with me in the woods (hikes or exploring) rather than the Adventurer.
So, MY "best" is probably the discontinued Adventurer. The boy scout version is still available.
