Swibo Fishing Knives: The Angler's Fillet & Boning Kit
, by Outback Edge, 6 min reading time
If you fillet your own catch, the knife matters more than almost anything else in the esky. A blade that flexes right lifts clean fillets off the frame with no waste; one that doesn't tears the flesh and leaves half the fish on the bone. Swibo — Victorinox's dedicated processing line — has quietly become the blade of choice for Australian anglers and deckies who want Swiss steel and a grip that holds when everything's wet and slippery.
This guide walks through the Swibo fishing range — how to pick the right fillet and boning blades, why the slicer earns its place, and the complete roll packages we've built for anglers who want the whole kit in one go.
Why Swibo for fishing
Swibo is made by Victorinox — the same Swiss stainless steel and quality control behind the Fibrox knives used in commercial rooms nationwide — but built specifically for the fishing and boning trade. Three things make it a standout on the water:
Grip when it counts: The Swibo handle is designed for cold, wet, fishy hands. It doesn't turn into a bar of soap the moment you're covered in slime and salt water.
The right flex: Swibo fillet blades are properly flexible — they follow the backbone and ribs so you take the fillet and leave the frame, not the other way around.
Corrosion resistance: Stainless Swiss steel shrugs off saltwater far better than cheap fillet knives. Rinse, dry, done. (For the full rundown, see Carbon Steel vs Stainless.)
Swibo fillet knives — flexible vs curved
The heart of the range. All are 20cm — the do-everything length for Australian species from bream and flatties up to snapper and mackerel.
Swibo 20cm Flexible Fillet Knife (5.8450.20)
The classic straight, flexible fillet blade. Long, thin and forgiving — it rides the bone and skins in one motion. The best all-round fillet knife for most anglers. Also available with a sheath (35979) if you want it protected in the tackle bag.
Swibo 20cm Curved Flexible Fillet Knife (5.8452.20)
The curved-blade version. That upswept belly gives you a cleaner sweeping stroke along the frame and more control when skinning — the pick for anglers who fillet a lot and want every gram off the bone. Also available with a sheath (35981).
Straight or curved? Straight is the safe first buy and easier to learn on. Curved is the upgrade once you've got your technique and want maximum yield. Plenty of serious anglers carry both.

Don't skip the boning knife
A fillet knife lifts the flesh; a boning knife handles the heavier work — heads, collars, big frames and trimming. A short, stiffer blade gives you the control a long flexible fillet knife can't.
Swibo 16cm Curved Boning Knife (5.8405.16)
A 16cm curved boner that's ideal for fish work and general trimming — grippy, sharp, and the natural partner to a Swibo fillet knife. There's also a wide-blade version (5.8407.16) for more rigidity. If you want the full breakdown of stiff vs flexible boning blades, read our Best Boning Knife guide.
The slicer no one else stocks
Swibo 30cm Round Tip Slicing Knife (5.8441.30)
Here's where Swibo pays off for the serious fish handler. A 30cm round-tip slicer portions large fillets, skins big fish, and cuts sashimi-clean steaks off a whole pelagic — work no fillet knife will do well. Almost no fishing retailer in Australia stocks one; we do.
The complete kits — Swibo roll packages
If you'd rather buy the whole setup once and be done, we've built two Swibo packages around a Kay Apparel 6-pocket nylon knife roll — everything organised, protected and ready to throw in the boat bag.
Swibo Deckie Roll
The core angler's kit: a 20cm flexible fillet knife, 16cm curved boning knife, 30cm slicer and an Edgemaster diamond sharpening steel, packed into a 6-pocket nylon roll. Four pockets filled, two to spare for your own additions. Everything you need to fillet your catch cleanly, in one tidy package. Ideal for the weekend fisho who wants quality blades without overthinking it. Choose Blue, Red or Black at checkout.
Swibo Offshore Fisherman
The full six-piece setup for people who fish hard: two boning knives (curved and wide), two fillet knives (straight flex and curved flex), the 30cm slicer and an Edgemaster diamond steel — every pocket of the 6-pocket nylon roll filled. Built for charter deckies, spearos and offshore crews processing serious volume. Nothing else on the Australian market packages the slicer in like this. Choose Blue, Red or Black at checkout.

Looking after your fillet knife
Swibo steel is tough, but salt is tougher. Rinse in fresh water, dry the blade fully, and store it in its sheath or roll — never wet in a drawer. A few passes on a steel keeps the edge honing-sharp between sessions; when it stops biting, give it a proper sharpen. Our Sharpening Steels guide and Stropping guide cover both.
Frequently asked questions
What length fillet knife is best for Australian fish? 20cm is the sweet spot — long enough for snapper and mackerel, controllable enough for bream and whiting. It's why the whole Swibo fillet range is built at 20cm.
Flexible or curved fillet blade? Straight flexible for learning and all-round use; curved flexible for maximum yield and cleaner skinning once you've got the technique.
Do I need a boning knife as well? If you process whole fish, heads or big frames — yes. The fillet knife takes the fillets; the boning knife does the heavier trimming a flexible blade can't.
Are these good for saltwater? Yes — stainless Swiss steel handles salt well. Just rinse and dry after every trip.
The bottom line
For Australian anglers, Swibo is about as good as it gets without stepping up to boutique Japanese steel: Swiss quality, the right flex, a grip that works when you're covered in slime, and — uniquely — a slicer and complete roll packages you won't find at the big chains. Start with a 20cm flexible fillet knife, or grab the Deckie Roll or Offshore Fisherman package and be sorted for every trip. Not sure which kit suits your fishing?
