Quick take
A 4 inch stainless steel bait knife with serrated upper blade and molded grip, sized for bait preparation and boatside tasks.
The Rapala RSB4 is a compact bait knife with a 4-inch stainless steel blade that is razor sharp from butt to tip, with a serrated upper edge. A molded comfort grip and finger guard keep the hand steady, and the open sheath is easy to rinse clean. It suits cutting bait and handling small boatside jobs, and the sheath hangs from a loop for one-handed access or the knife can ride on a lanyard.

- Cutting bait and preparing tackle
- Filleting small fish
