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.

Best for

  • Cutting bait and preparing tackle
  • Filleting small fish
  • Boatside work where a multi-task knife helps

Skip if

  • You need a full-size fillet knife; this is compact
  • You prefer non-serrated blades for clean cuts

Strengths

  • Serrated upper blade excels at cutting through bait skin and scales
  • Molded comfort grip reduces hand fatigue
  • Open sheath with lanyard allows one-handed access

Trade-offs

  • 4 inches is compact for larger fish filleting
  • Serrated edge is harder to sharpen than straight blade
  • Stainless steel requires rinsing to prevent corrosion
