I have honestly no idea what this means. Keep seeing it on chisel and crowbar tool descriptions, the biggest offender being Toolbank (not helped by their already terrible category system!).
Here is an example of what I mean, on the similarly perplexing 'handy bar' (isn't this just a utility bar.). Picture is attached:
'The Handy Bar is forged half round, for added strength and less weight.'
Sounds great.... no idea what it means!!!
