I would agree with you that hand axes and more advanced tools will usually
display the features you described, yes I have made and used stone tools and
studied lithics, but not all do and in many cases it is the context the
artifact is found in that determines whether it is a tool. Pebble tools,
rough scrapers, and used flakes are common exceptions even in more
"advanced" tool kits.
