I'll agree with that, but also say that real men do their research to find a product that fits their needs. There's nothing unmanly about talking about why you like your wallet, unless it's because it matches your purse.As my post is meant to mean. Real men don't have wallets for sissy wardrobe reasons and to change em like women's purses!!! Come on guys grow a pair!
I have a Mitchell's Money Clip wallet. It's basically a simple card holder wallet with a metal clip to hold your bills. It's really thin and convenient, plus you can easily carry about 10 cards in the 4 slots. I have to have several on me for work and it works well. Mine is the American cowhide model. They have some finer leathers, but the price goes along with them. I think it's one that will last a few decades.

As for the original question, I toss a wallet when it wears off. That normally takes 3 years or so.
