Dexter Sani-Safe Knives

A 7-inch fillet blade suits trout, walleye, bass and other fish of moderate size. This Sani-Safe 7-inch fillet knife from Dexter-Russell has a narrow blade with just the right amount of flex, in Dexter’s words, to follow the backbone and rib cage and then run under the skin without tearing the fillet. It excels at skinning out fillets and working around the bones of medium-sized fish such as trout, snapper and bass, where a paring knife lacks reach and a 9-inch blade is cumbersome.The Sani-Safe series started in 1941 as Dexter’s line for commercial kitchens, and Dexter still calls it the gold standard in foodservice. The textured grip holds in a hand covered in slime and scales, and the guard keeps fingers off the edge when the blade pushes through a pin bone. Dexter knives are especially popular in the Northeast, and fishermen are among the customers who buy them from us. It suits commercial fishmongers, charter boat captains and high-volume prep cooks who need a reliable, high-yield fillet knife that can be sanitized quickly. The steel is softer than that of premium Japanese knives, which makes it very tough and resistant to chipping, though it needs more frequent honing to keep its out-of-the-box sharpness. It is more flexible and more slip-resistant than a Wüsthof fillet knife, which makes it safer in wet conditions, though it lacks the polished look of a Japanese sujihiki.

An 8-inch blade is long enough to fillet a striped bass, a bluefish or a mid-size salmon in one smooth pass from collar to tail, and it also suits large salmon, flatfish and medium-sized pelagic species. The S133-8 is Dexter-Russell’s Sani-Safe 8-inch narrow flexible fillet knife, and shoppers search for it on our site by that model number.Its narrow blade flexes enough to ride over the rib cage and lift a fillet cleanly, then lies flat against the board to skin it. Dexter recommends it for filleting fish and also for trimming fat from meat, so it earns a place in a home kitchen as well as a tackle box. Fishermen and home cooks both buy this size, and it carries Dexter’s long history in Southbridge, Massachusetts, where the company has made knives since 1818.
Choosing an 8-inch Fillet KnifeFor thicker, heavier fish such as cod and grouper, the Sani-Safe 8-inch Wide Fillet Knife is stiffer. The V-Lo 8-inch Fillet Knife offers a similar flexible blade with a cushioned handle, and Dexter’s leather sheath for 8- and 9-inch fillet knives protects the edge in transit. Learn More

Large, firm-fleshed fish such as cod, haddock, grouper and striped bass push back against a thin, whippy blade. Dexter-Russell built the Sani-Safe 8-inch wide fillet knife with a blade it describes as stiff but able to give a little when needed, a semi-stiff profile that keeps cutting straight through heavy fillets.The extra blade height adds control when cutting a fillet into portions or steaking a fish across the bone line, and Dexter also recommends it for large cuts of meat. It also serves as a churrasco knife for slicing grilled meat. Paired with a narrow flexible knife, it handles the start of the cut and the portioning, and the flexible blade handles the skinning. The wide blade also keeps the knuckles clear of the board during long cuts. The knife is built in Southbridge, Massachusetts.

A fillet knife on a boat needs somewhere safe to live between fish. This set pairs Dexter-Russell’s Sani-Safe 7-inch narrow flexible fillet knife with the WS-1 scabbard, a white polypropylene sheath with a riveted strap and belt loop, so the knife can ride on the hip at the cleaning station or go into a tackle bag without exposing the edge.The blade is narrow and flexible for panfish, trout and flounder, and it slides under the skin cleanly. During high-volume filleting, we recommend regular use of a ceramic honing rod to realign the flexible edge. Dexter grinds each blade individually. The scabbard holds a straight blade up to 9 inches, so it can later carry a longer Dexter fillet knife too, though it will not hold curved knives.Shoppers search our site for this exact knife-and-sheath pairing, and it is a practical first fillet knife for an angler who needs both.
