How did you happen to pick those two knives to choose from? They are as different as nite and day. I love the Gayle Bradley, but I don't carry one, as it's a little large for me. When I say LARGE, I'm generally talking about grip-thickness, because that is what I notice IN MY POCKET and IN MY HAND. The blade-length, whether 3" or 3 1/2" doesn't mean much to me for my casual EDC.
That being said, the Gayle Bradley grip-thickness is about 0.060" THICKER than the "large" CRK knives that I love and carry every day.
Benchmade is a good brand. So is Spyderco. If you like a smaller, shorter knife, then perhaps you should check out the Spyderco line of smaller EDC folders. My favorites are the Sage series of folders, the Native series, the Stretch and the Caly3 series of knives. These are all shorter blades of 3"(several models available at 3 1/2"); they are available in different scale materials and blade-steels within each series. You can get scale materials of FRN, G-10, carbon fiber, and titanium, and blade materials of excellent steels like S30V, VG-10 and the outstanding ZDP-189 and Hitachi Aogami SuperBlue blade-steels which Spyderco fans seem to love.
These are all slim in the hand and light in the pocket, and within each series is a model to fit your wallet.
These are the knives that I suggest to my friends and gift to my relatives.
