Overview
A KastKing bait knife with a 5 inch vanadium steel blade and a thermoplastic elastomer handle, sold with a sheath and case for on the water cleaning and bait cutting.
Vanadium alloy steel is chosen in fishing knives for its resistance to the corrosion that saltwater and fish slime cause faster than fresh water use does. The TPE handle is meant to stay grippy when wet, a common failure point on cheaper bait knives whose handles turn slick.

- Thermoplastic elastomer handle
- Includes sheath and case
- Orange color
Who it's for
Anglers who need a compact bait or light fillet knife for on the water use, sold complete with a sheath and case rather than a bare blade.
Strengths and trade-offs
Drawn from this product's published specifications.
- Corrosion resistant vanadium steel blade
- TPE handle built for wet grip
- Comes with sheath and case
- 5 inch blade is compact, not suited to filleting large fish
- Orange is the only color listed
Performance notes
The vanadium steel edge resists the corrosion saltwater exposure causes faster in plain carbon steel blades, and the TPE handle is built to hold grip when hands are wet from fish slime or water, the two failure points most bait knives run into on the water.
