Thanks all. I do feel really good about getting it back.
And than you Jerry for your offer to confirm current market value, but it won't be necessary. The kid's father was not aware it was a stolen knife. The father is cool. Offered restitution and even offered more for "pain and suffering" due to my temporary loss. I am good with that. I was a kid once (many, many years ago).
The short term "owner" apparently decided to sell it after discovering he couldn't break it. Sure looks like he tried.
It needed sharpening bad, and the mid blade chip turned out to be a dent which I worked out without removing much metal.
INFI is amazing stuff.
