I have the soft hands of an office worker, so I tend to notice hotspots on knife handles very quickly. Now, on the Cybertool L and M, the bit driver tends to dig into my pinky when I use the large blade, no matter what bit I put in the closed driver. It's rather annoying as first world problems go. It's not a problem with S, as the hand wraps easier around the thinner handle. I was pretty curious as how the Cybertool Lite would handle, as the bit driver is farther away from the scales (on the L and M, the order is “scale, opener layer, bit driver”, on the Lite it is “scale, opener layer, magnifier and light layer, bit driver”). Funny enough, the hypothesis turned out to be correct. The extra distance places the bit driver in an area where the finger is curved a little up from the closed tools.
The Cybertools I think are most comfortable are the S and Lite, in other words the thickest and thinnest models. (Though the difference between the L and Lite is just half a millimeter.) I guess I'll just embrace my inner propeller head and carry Vic's most geeky knife with pride. (I'm a programmer, so it comes pretty naturally...)
I think it is interesting how our hands work. The number and selection of tools make a huge difference to me in how comfortable I find a SAK to handle.
