"without any explainable lawful purpose"

That is a rather tortured definition of "double edged’ that is not in common use.

If we are going with magiver’s interpretation, then all knives would have 4 to 8 edges, no? :confused:

Exactly. I could be a farmer, but just try carrying the scythe into the bank.

Why is a slingshot considered inherently more dangerous than a bow? Both can be used as weapons, but both can also be used for sport, and pretty much the same sorts of sport in both cases. Is it just that a slingshot is more easily concealable?

Roland, is that you?

I had to look up ** cestus**.

A cestus (plural cesti) is an ancient battle glove, sometimes used in pankration.

So I am pleased to clear that up for you.

Hah!

WAG: A slingshot is not only far easier to conceal, it can also be used concealed. If you use a bow to kill somebody, that arrow sticking out of his chest is going to be a rather big clue.
If you put a stone in a sling-shot and kill somebody by hitting him on the head, you have a good chance that it will be considered an accident if the stone could have fallen from above. Or use a round object that disintegrates upon impact.

In Dorothy Sayers crime novel Murder must advertise the murderer uses a sling-shot taken from an office boy to fire a small stone artifact from a ceiling window at a man going downstairs; the man is knocked unconcious and falls down the stairs. Everybody believes that he stumbled and was killed by the fall; the stone artifact found on the stairs is believed to have slipped out of his pocket at some time.
