Why So Violent?

The Sap Cap is a “self-defense” hat with a lump of heavy metal sewn into it so you can doff your hat to your assailant and then drive his nose into his brainpan. Remember, though: any hat you don’t know how to use belongs to your opponent. Also, the commenters on the sell-page say it makes a crummy hat.

I prefer a bag of frozen oranges but that's just me.
