Could two dissimilar items both be perfect for one purpose? (Plus more questions of perfection)

Perfection can exist, hypothetically a ball could be perfectly circular, though in reality it’s a very highly unlikely event.

Could a iteam with more than one purpose be purfect at it’s higher cause if one of it’s purposes hinders the other purpose?
The first question that popped into my head is this.
Could you have a shape that is a perfect circle and also a perfect square?
No, any one item can only be one or none of these shapes at any one time. Maybe I’m thinking about this in the wrong way, lets try it this way. “could there be a perfect hunter?”
There are a myriad of factors that make up a animal’s hunting abilities, two for the examples I’ll use is speed and strength.
I’m not asking for the perfect runner or for perfection in it’s strength, I’m only asking is it perfect at one single point, unlike the circle and the square witch was a dichotomy.
(Is my logic correct my last assumption?)

Now to the main question: Would it be possible to have one item that is perfect at a individual job and then to create a different item that would also be perfect at the same job?

(Sorry for questions like these, it make it look like I’m trying to be smart and not succeeding)
