A sign of a poor gunsmith is using normal screwdrivers on a gun. However not all individuals that like guns know the difference between a normal and gunsmith screwdriver. This post will fix that.
The screw on this firearm was damaged by a kitchen table gunsmith using a normal tool box flat-head screwdriver on a firearm.
I am a kitchen table gunsmith myself, and before I learned about using hollow ground screwdrivers on my firearms I buggered up plenty of firearms.
You see a normal screwdriver is taper ground - the manufacturer took a shaft of steel, and then smashed the end into a wedge.
