Favorite Scrapyard....
Large blade right now is my Regulator Bulldog. It the longest scrapyard I have. I gave my DF to a crazy Jarhead in trade for the upcoming 911 (which he has already ordered AND is making a cordura oversheath for the kydex insert he is going to make.
I really like my 311, light, handy and Sheeple friendly. But I think I would have to go with my Muppy. There's just something about it that keeps drawing me back to it no matter what knife I get.
Course the BWM is a really nice blade to, but you said Scrapyard.
As far as "I'll use it for ANYTHING blade", I would have to go with my Regulator.
SO I don't actually have A favorite, but a couple three depending on the use.
