From the Bench
A Firehole original design. The continuous curve is what lets you seat a bigger bead than the hook size would normally allow, which is the whole reason it exists.
Barbless by Design
Every Firehole Sticks hook is barbless. Cleaner release, less handling, fish back in the water faster.
