Fear Tim Duncan's knees, no matter how fragile or old they are.

Everything seems to be custom-made in the NBA these days, and Duncan's knee braces are no exception.

In addition to a Punisher-themed brace, Timmy has a collection of other airbrushed support systems, according to Trey Kerby of The Score.

Seriously, there are no words—other than awesome.

This is bodily protection at its best. Whether you believe knee braces actually serve a genuine purpose or not, there's no denying Duncan's set is scary, making them too cool.

Tailoring your sneakers to fit your personality is one thing, but designing a trio of knee-bearing props is no joke.

Just looking at the Punisher one sends a shiver down my spine. It (almost) makes me wish I had a need to sport one of these bad boys. I may even get my own to wear to the supermarket or when I play pickup against imaginary opponents. They're that spectacular.

To think, there are those who actually consider Duncan boring and uninteresting. Nothing could be less mundane than customizing equipment that actually intimidates your opponent.

Too bad Duncan doesn't wear a goalie mask when protecting the rim. I'd love to see what he would fashion there.

If only every 37-year-old's knees could be as delicately exciting and elegantly dressed as Duncan's.
