I was gifted a SAK a while ago. Originally the scales were camo, which made it hard to find when dropped in grass. I didn’t use it much for fear of losing it.
So gave it new yellow scales, the plus ones that add the pen slot, then added the pen, a red pin and and corkscrew screwdriver.
Put it on a hi-vis nylon cord for good measure.
This is gonna be my new camping companion!
I wouldn’t try it, myself. This was a factory swap. The more common 91mm model with the corkscrew is the Spartan. I was in a youth organization at the time that frowned on corkscrews because apparently children shouldn’t be drinking wine.
