I use it like a small pocket knife. It's made to be a small keychain knife, but I keep throwing it in my pocket instead of putting it on my keyring.
That keychain hatchet is super cool! I fired up the Google Machine and searched the inter web but could not find it anywhere. I would love to know where you found it.
You're fine. Yea, it is a TM Hunt Custom Knives Little Billy Bad-Axe. And thanks! It's a fun little sharp to play around with.
