I was wondering if all lockring tools are created equal.

I'm trying to rebuild a bike and it's got this bottom bracket that seems to come apart with a lockring. I was wondering if it is extremely necessary to remove the lockring with its specific type of lockring tool, or is it possible to just buy a general hook-esque lockring tool and remove most (if not all) lockrings with it?

I'm not particularly a heavy lockring remover or a bike rebuilder, so I really don't want to buy "that specific lockring tool that only applies to the drive side of the bottom bracket on the 1953 version of whatever bike." I am trying to avoid spending too much money on allocating a plethora of what would be relatively minimally used tools.

Any other ways of removing lockrings?

The type of bottom bracket cup(?) is pictured below.
