That is a most interesting observation (love the Harley analogy! back in the day they called those 'monkey hangers' on their choppers).
It is true many weapons were formed after various tools and implements, but not sure on these distinctively curved bars being so fashioned.

Im more curious on what in the world 'garsoe' means, and where Egerton got the term. As I noted the suffix 'gar' means fort in dialects in Gujerati areas, but hope linguists here can offer some insights.
