Standard tools – Single-edge razor blade.

Gear ~ Single-edge razor blade

Generic Single-edge razor blade — 3.9 grams

One of the fundamental human tools – the wedge – doesn’t show off simple refinement better than this. Useful for trimming gear, First Aid surgery, and other basic tasks that need a super-sharp blade. Oddly enough, shaving is no longer one of them. They’re both delicate and dangerous, but when it’s the right tool for the job, a single-edge blade is indispensable.

Bottom line:

On my next walk I’ll carry one of these in my Sharps Kit. I always do, and generally include one in my 30-day re-supply package.
