Here's an example of why having a savagely thin blade can be useful
I needed to remove the sheathing from this flash trigger cable for a project I'm working on for my wife's photo studio.
The sheathing is some kind of very tough vinyl-like material and as I tried to strip it the usual way I just wasn't making any progress. If I pressed too hard I would likely damage the internal wires. So the solution was to use the savage
Wenger small blade and slide it down lengthwise against the cable. This produced a very thin sliver of cable sheathing. On the second pass the internal wires became visible and I was able to split the sheathing with a fingernail and pull it back and cut if off. Having a super-thin, super-sharp knife made this task much easier and controllable.
