Smith's RegalRiver 4in Folding Flex Fillet Knife Green-Gray TPE Handle 400 Series SS Blade SA51383

At the heart of this knife is a 4-inch razor sharp stainless steel blade crafted from durable 400-series stainless steel. It delivers the strength and wear resistance needed for repeated use while maintaining a keen edge for clean, controlled cuts. The flexible blade design is a major advantage when it comes to delicate filleting work. It moves smoothly along bone structure, making it easier to remove rib bones, trim away skin, and handle fine-detail cutting tasks with accuracy and confidence. A secure locking mechanism keeps the blade firmly in place during use, giving you stability when every cut counts.

The handle is designed with both comfort and function in mind. Featuring a green and gray finish and ergonomic profile, it includes non-slip TPE soft-grip inserts that enhance control even in wet or slippery conditions. Whether your hands are damp from the water or busy with a long cleaning session, the grip stays steady and dependable. This thoughtful design helps reduce fatigue while improving safety at the fillet table, making extended prep work more manageable.

Smith’s didn’t stop at performance—they built in smart utility features that anglers actually use. The handle includes a built-in carabiner for quick attachment to packs, belts, or gear loops, keeping it within reach when you need it most. A tether-ready lanyard hole adds an extra layer of security, so it’s always close at hand near the water. To top it off, an integrated bottle opener brings a bit of convenience to those long days outdoors, because time spent fishing has a way of working up a thirst.

The RegalRiver 4in Folding Flex Fillet Knife is perfectly suited for processing smaller fish, offering a balance of portability, control, and cutting precision that makes it a reliable companion for any fishing trip. It’s built to perform season after season, delivering consistent results without complication.
