Product Description

Precision Fish Preparation Starts With the Right Knife

Filleting fish is one of those jobs where the right knife makes an enormous difference.

A broad chef knife may be excellent for general preparation, but it isn’t designed to carefully follow the backbone, work around rib bones or separate delicate flesh from skin.

That’s where the MAC SF-85 Superior Fillet Knife comes into its own.

Its specialist 21cm blade provides the length and precision required for controlled fish preparation, allowing you to work smoothly through delicate flesh while maintaining excellent awareness of the blade.

Whether you’re preparing freshly caught fish at home or processing seafood in a professional kitchen, the SF-85 is built for accuracy.

Designed for Clean, Controlled Filleting

A good fillet knife should allow the cook to work with the natural shape of the fish rather than forcing through it.

The SF-85’s long, narrow blade is ideally suited to tasks including:

• Removing fillets from whole fish
• Working alongside the backbone
• Separating flesh from rib structures
• Skinning fish
• Trimming fillets
• Portioning seafood
• Removing excess fat and connective tissue
• Preparing clean serving portions

Greater control means more of the valuable flesh remains on the fillet rather than being left behind on the frame.

For anyone who regularly prepares whole fish, that can make a meaningful difference.

The Advantage of a 21cm Blade

Blade length plays an important role in filleting.

At 21cm, the SF-85 provides enough reach to handle a broad variety of fish sizes without becoming unnecessarily cumbersome.

The additional cutting length allows for:

• Longer slicing strokes
• Smoother filleting movements
• Cleaner skin removal
• Better control on medium and larger fish
• More consistent portions

Instead of using numerous short, sawing movements, you can guide the knife through the fish with longer and more deliberate strokes.

Ideal for Australian Seafood

For Australian cooks and anglers, a quality fillet knife can be invaluable.

The SF-85 can be used when preparing species such as:

• Snapper
• Flathead
• Salmon
• Trout
• Barramundi
• Bream
• Kingfish
• Whiting
• Tailor
• Mackerel

Different fish require different techniques, but having a purpose-built fillet knife gives you the control required to adapt to the job.

---

Excellent for Skinning Fish

Removing fish skin cleanly can be difficult with an ordinary kitchen knife.

The long profile of the SF-85 allows you to work between the skin and flesh while maintaining a controlled cutting angle.

With proper technique, this helps:

• Reduce flesh left on the skin
• Produce cleaner fillets
• Improve presentation
• Minimise waste

For professional kitchens where portion quality matters, that precision is especially valuable.

---

Reduce Waste and Improve Yield

One of the biggest reasons to invest in a quality fillet knife is yield.

When processing a whole fish, every piece of usable flesh matters.

A knife that allows you to stay close to the frame and ribs helps minimise unnecessary waste.

That is beneficial whether you’re:

• Running a commercial kitchen
• Buying premium whole fish
• Catching your own seafood
• Preparing fish for family meals

Better technique combined with the right knife can result in cleaner fillets and more usable product from each fish.

---

More Than Just a Fish Knife

Although fish preparation is its primary role, the SF-85 can also assist with other precision trimming jobs.

It may be useful for:

• Trimming boneless chicken
• Removing excess fat
• Cleaning up tenderloin
• Removing silver skin
• Portioning delicate proteins
• Fine meat preparation

Its narrow profile allows it to work in places where a broad chef knife may feel awkward.

That said, it remains a precision blade rather than a heavy-duty butcher knife.

SF-85 vs a Chef Knife

A chef knife is one of the most versatile tools in the kitchen—but specialist jobs benefit from specialist knives.

A chef knife excels at:

• Chopping
• Dicing
• Mincing
• General slicing
• Vegetable preparation

The SF-85 excels at:

• Filleting
• Skinning
• Trimming
• Working around fish bones
• Precision protein preparation

If you prepare whole fish regularly, the two knives complement one another rather than compete.

---

SF-85 vs BNS-80 Fillet Knife

Customers may also compare the SF-85 with the MAC BNS-80 20cm Fillet Knife from the Professional range.

The most obvious practical difference is the blade length:

BNS-80 – 20cm
A professional-series filleting option with a slightly shorter blade.

SF-85 – 21cm
A Superior-Series option with a little additional reach.

For your store, linking these two products together gives customers the opportunity to compare MAC’s filleting options rather than leaving the site to research elsewhere.

---

Part of the MAC Superior Series

The SF-85 belongs to MAC’s Superior Series, a range designed around practical cutting performance and lightweight handling.

This philosophy is particularly useful with a specialist knife such as a fillet knife.

Fine control is critical when working close to bones or skin, and unnecessary weight can make delicate movements harder.

The SF-85 is designed to remain responsive in the hand throughout the preparation process.

---

Japanese Craftsmanship

MAC knives are manufactured in Japan, drawing on a long tradition of highly refined kitchen knife manufacturing.

Japanese knives are valued by cooks worldwide for qualities such as:

• Sharp cutting performance
• Precise blade geometry
• Lightweight handling
• Excellent control

Those qualities make particular sense in a fillet knife, where accuracy and blade positioning are critical.

---

Professional Seafood Preparation

The SF-85 is well suited to:

• Restaurants
• Seafood restaurants
• Hotels
• Catering operations
• Fish retailers
• Professional chefs
• Recreational anglers
• Home seafood enthusiasts

For kitchens purchasing whole fish rather than pre-cut portions, a dependable fillet knife can become one of the most important specialist tools in the knife kit.

Care Instructions

Fish and seafood can expose knives to moisture, salt and acidic ingredients, so proper care is especially important.

For best results:

• Wash the knife by hand immediately after use.
• Use warm water and mild detergent.
• Dry thoroughly before storage.
• Never leave the knife soaking in water.
• Avoid dishwashers.
• Use timber or suitable synthetic cutting boards.
• Do not use the knife to chop through hard bones.
• Avoid frozen foods.
• Store safely in a knife block, magnetic rack or blade guard.
• Sharpen appropriately when required.

If the knife has been used around saltwater or freshly caught seafood, washing and drying it promptly is particularly important.

Why Buy the MAC SF-85?

The MAC SF-85 Superior Fillet Knife is designed for the moments when precision matters more than brute force.

Its long 21cm blade gives you the reach needed to work through whole fish while its narrow profile helps you stay close to bones, skin and natural contours.

For professional chefs, that can mean cleaner presentation and improved yield.

For anglers and home cooks, it means getting more from the fish you’ve purchased—or caught.

If seafood is a regular part of your kitchen, the SF-85 fills a role that even an excellent chef knife simply isn’t designed to perform.
