in the 50's when I was a Scout, I had a neighbor that was a retired machinist (merchant seaman)...at the time there was a pair of pliers available that had a straight blade screwdriver bit on one handle end and a blunt tapered shank on the other.. he would re profile the blunt end, and cut a Phillips style point with a triangular file...a multi tool ahead of it's time... I used it for many years on campouts.. unfortunately it disappeared over time
