I believe that "low skilled attack" also includes the ability to search the internet and watch a video. There are literally thousands of videos on YouTube with demonstrations of low skilled attacks using improvised tools.

For example I made a shim and opened a lock I own in less than 30 minutes after watching one of his videos that featured a similar lock. I had never opened a lock without a key before that day, don't have much use of two fingers on one hand, and my toolbox fits in a kitchen drawer.

For your list of common low skill attacks which have widespread effectiveness I would also include shimming, hammering, and cutting. Also in the case of locks with electronics associated with them, strong magnets.
