A choil is a good place for hang ups. Just my personal opinion.

A choil does not give you a longer cutting edge, just a notch that can be hung up on
in some uses. Also as noted above could be a weak point in the structure that does
not necessarily need a 30 cal incident to fail, but if properly rounded should be ok.
They do look nice though.
Again, just my 2 cents.
