The MAC Professional Bread Knife MSB-105 is a 27cm serrated knife designed specifically for slicing bread and cooked roast meats cleanly and consistently. It is part of MAC's Professional series, manufactured in Japan using a combination of modern production methods and traditional hand-finishing by skilled craftsmen.In a busy kitchen environment, the quality of a bread knife often goes unnoticed until it starts to let you down. A blade that crushes rather than cuts, or drags through a crust rather than gliding cleanly, slows service and affects presentation. The MSB-105 uses a strong serrated edge that maintains contact with the surface without compressing the crumb beneath, producing clean, even slices with minimal effort across a full service period.From a practical standpoint, the knife offers a few advantages worth noting: Serrated edge cuts cleanly through hard crusts and soft interiors without tearing Comfortable handle reduces hand fatigue during extended prep work Japanese steel construction supports long-term edge retention Well balanced for controlled slicing of both bread and cooked meats Hand wash only — straightforward care that helps maintain the edge It is worth being clear about one limitation: this knife is hand wash only and is not suited to dishwasher use. That is a standard consideration with knives of this quality and is not unusual, but it is worth factoring into your kitchen's workflow if you run a high-turnover operation.The MSB-105 is well suited to professional kitchens, cafés, and restaurant operations where bread service or carving is a regular part of the day. It is a single-purpose tool and performs best in that role rather than as a general-purpose blade. If you need guidance on building out a knife set or matching this to your existing MAC range, the team is happy to help you think it through.
