That's the one! Flippin' sweet gut knife.

I just bought the Outdoor Edge version. Heavy fixed blade + sheath for $14 bucks on Amazon. Not bad for a specialized tool that will only be used a couple of times a year (hopefully). It would make for a great mushroom knife. Nice inside cutting angle and a blunt tip in case you trip and stumble. Hunter orange handle stands out on the ground.

We'll see how well it works next year. Or during spring Morel season.
