If you're on the prowl for a barracuda or a similarly toothy target, you need to ensure they won't just bite through the line and swim away with your fly. With the RIO Toothy Critter Li 7. 5' Stainless Wire With Snap, their teeth will be unable to slice through the shock tippet, so you can pull in your prize. This version includes a snap link connecting the wire tippet to the ultra-stiff nylon leader.
