Product Description

Built for Big Loaves and Clean Slices

Not all bread knives are created equal.

If you regularly bake or buy large sourdough loaves, wide artisan breads or oversized bakery products, a short bread knife can feel limiting.

That’s where the MAC SB-105 Superior Bread Knife stands out.

Its generous 27cm serrated blade gives you the reach to work through large loaves with long, controlled strokes rather than relying on repeated short movements.

That means smoother slicing, cleaner presentation and less crushing of the soft crumb inside.

For bakeries, cafés, restaurants and bread-loving households, the SB-105 is built for serious slicing.

The Advantage of a 27cm Bread Knife

Blade length matters when working with bread.

A longer blade allows more of the cutting edge to engage with the loaf at once.

That can help with:

• Large sourdough loaves
• Wide artisan bread
• Baguettes
• Ciabatta
• Large sandwich loaves
• Large cakes
• Brioche
• Bakery trays and baked goods

Instead of making multiple short cuts, you can use longer, more efficient strokes.

That makes the SB-105 particularly useful in professional kitchens where speed and consistency matter.

Designed for Crust Without Crushing the Crumb

A good bread knife must handle two very different textures at the same time:

• A hard or crisp exterior
• A soft, delicate interior

A straight-edged knife often needs too much downward pressure to break through the crust.

That pressure can compress the loaf before the blade even begins to cut.

The SB-105’s serrated edge grips the outer crust and works through it gradually, helping the knife cut without forcing down on the bread.

The result is:

• Cleaner slices
• Less crushing
• Better crumb structure
• Reduced tearing
• Better presentation

That difference is especially noticeable with artisan and sourdough breads.

---

Excellent for Sourdough

Sourdough is one of the toughest challenges for a bread knife.

A thick, deeply baked crust can resist an ordinary kitchen knife, while the airy interior can collapse under pressure.

The SB-105 is well suited to this type of loaf because its serrated edge can bite into the crust while the long blade gives you the reach to work across the full width of the bread.

For serious sourdough bakers, that makes a dedicated long bread knife a worthwhile upgrade.

---

Ideal for Bakeries and Cafés

The 27cm blade also makes the SB-105 highly practical in commercial environments.

It can be useful in:

• Bakeries
• Cafés
• Restaurants
• Hotels
• Catering kitchens
• Pastry kitchens
• Commercial sandwich prep

When dozens of loaves, rolls or cakes need to be portioned, a longer bread knife can improve both speed and consistency.

---

More Than Just Bread

Like other high-quality serrated knives, the SB-105 can also be useful for selected foods with a firm exterior and softer interior.

That includes:

• Large tomatoes
• Melons
• Pineapple
• Cakes
• Sponge cakes
• Layer cakes
• Pastries
• Large sandwiches and filled rolls

Its long blade can be particularly helpful when portioning oversized baked goods or cakes.

---

Excellent for Cakes and Pastry

The long serrated profile of the SB-105 makes it valuable for pastry work.

It can be used for:

• Levelling cakes
• Portioning sponge cakes
• Cutting layer cakes
• Slicing brioche
• Cutting pastry products

A long blade gives you a better chance of maintaining an even cut across the full width of the item.

For presentation-focused kitchens, that can be a major advantage.

SB-105 vs BS-90 – Which Should You Choose?

You now have two strong bread-knife options in the catalogue.

MAC BS-90 – 22cm

Best for:

• Standard home loaves
• Smaller kitchens
• Everyday bread slicing
• Cakes and pastries
• Compact handling

MAC SB-105 – 27cm

Best for:

• Large sourdough
• Wide artisan loaves
• Commercial bakery use
• Longer slicing strokes

The difference is primarily about reach and scale.

If you regularly handle large loaves, the SB-105 is the more capable option.

Part of the MAC Superior Series

The SB-105 belongs to the MAC Superior Series, which focuses on sharp cutting performance, lightweight handling and practical professional use.

This makes the knife well suited to repetitive slicing tasks.

Even with its 27cm blade, the aim is to give you reach without unnecessary bulk.

That makes the knife easier to guide through bread and baked goods with controlled movements.

Japanese Craftsmanship

MAC knives are manufactured in Japan and have earned a strong reputation for combining Japanese cutting performance with practical everyday kitchen design.

• Avoid putting the knife in a dishwasher.
• Do not use it for bones or frozen foods.
