KastKing Speed Demon Pro 7-inch Fillet Knife — Flexible G4116 Stainless, Non-Slip Handle

The KastKing Speed Demon Pro 7" Fillet Knife is a flexible, razor-sharp fishing fillet knife built with German G4116 stainless steel and a non-slip polymer handle for precise filleting and easy cleanup.

Whether you’re cleaning a freshwater bass or filleting a saltwater snapper, the Speed Demon Pro 7" blends blade flexibility with long-lasting edge retention to help you make smooth, efficient cuts. Designed for anglers who want a dependable mid-length fillet knife, this model balances control and reach, and comes with a protective sheath for safe transport and storage.

How does the 7" blade make filleting easier?

The 7-inch blade offers enough length to work along the contour of medium to large fish while remaining easy to control for delicate trimming. Its flexible profile lets you follow bones and skin without tearing meat, producing cleaner fillets with less waste.

• 7" flexible blade for contour-following cuts
• Thin edge reduces resistance for smoother slicing
• Designed for medium to large fish like trout, bass, and smaller saltwater species

What material is the blade made from and why does it matter?

The blade uses G4116 German stainless steel, chosen for corrosion resistance and edge durability in both fresh and saltwater conditions. That means fewer trips to the sharpener and reliable performance after repeated use on wet, salty decks.

• G4116 German stainless steel resists rust and stains
• Holds a razor edge longer than common stainless blades
• Black finish helps hide wear and reduces glare

Is the handle comfortable and safe to use on wet surfaces?

The Speed Demon Pro features a super polymer, non-slip grip shaped for ergonomic control and safety. It remains grippy when wet and is easy to rinse clean, so you can maintain a secure hold during repetitive filleting tasks.

• Textured polymer handle for confident grip in wet conditions
• Ergonomic shape reduces hand fatigue during long sessions
• Material resists deterioration from sun and salt exposure

What protection and storage does the knife include?

Each knife ships with a lightweight, durable sheath that secures the handle and protects the blade between uses. The sheath includes drainage slots so water escapes, helping the blade stay drier and sharper over time.

• Locking-style sheath keeps blade and handle safely enclosed
• Drainage openings prevent standing water inside the sheath
• Lightweight construction for easy carry on the boat or in a tackle bag
