Mercer Culinary Millennia 10" Wide Wavy Edge Bread Knife Review

Introduction

A serrated knife is one of the three knives every kitchen really needs, alongside a chef’s knife and a paring knife. Most people call them bread knives, but the best ones handle far more than that. In an 11-knife comparison spanning blade lengths from 9 to 11 inches and prices from $14 to $180, one affordable favorite kept coming out ahead: the Mercer Culinary Millennia 10” Wide Wavy Edge Bread Knife. It has won comparisons before, and it is still the serrated knife to beat.

Why Every Kitchen Needs a Serrated Knife

Serrated knives earn their place in the core trio because of the jobs no other knife does well: sawing through a crusty sourdough boule, cutting delicate challah without crushing it, and slicing layered sandwiches so they look tidy instead of messy. Testers put each knife through exactly those tasks, plus layered millionaire’s shortbread with its caramel, chocolate, and shortbread stack, and straight-through chocolate cuts.

Serration Shape: Pointier Works Better

The first thing that separated winners from also-rans was the shape of the serrations. Blades with taller, pointier teeth got better initial purchase on food than rounded, scalloped edges that tended to slip before biting in.

Fewer Serrations Cut Cleaner

The second finding was genuinely surprising: fewer serrations performed better. Tester favorites had between 29 and 34 serrations along the blade. Knives packed with tiny micro-serrations alongside larger teeth, one with 96 serrations in total, struggled. When slicing a layered sandwich, a 96-serration blade slipped and produced a messy cut, while a knife with pointy serrations and fewer of them cut right through cleanly and easily. It is counterintuitive, but more teeth do not mean better performance here.

Blade Length and Height Matter

Usable cutting length turned out to be critical. Testers wanted at least 8 1/2 inches of cutting length. A shorter knife with only 7 1/4 inches got stuck partway through a sourdough boule because it simply lacked the reach to cut through the center in one pass.

Blade height mattered too. Taller blades were easier to control through a cut, and extra height at the heel, such as 1 1/2 inches, left more room for fingers underneath the handle. The winning knife checks both boxes.

The Winner: Mercer Culinary Millennia 10” Wide Wavy Edge Bread Knife

The Mercer Culinary Millennia 10” Wide Wavy Edge Bread Knife stood out for getting all the fundamentals right. It has the right kind of serrations, the right number of them, and a comfortable handle. It has won comparisons before, and it remains the serrated knife to beat.

Better still, it retails for just under $25, making it a relative bargain in a lineup where prices ranged up to $180. For a knife that completes your essential three-knife set, that combination of proven performance and low price is hard to argue with.

Buying Advice

If you are building or upgrading your kitchen knife set, prioritize the same qualities the testing highlighted: a blade with at least 8 1/2 inches of usable cutting length, taller teeth rather than scalloped ones, and a serration count in the 29 to 34 range rather than a dense field of micro-serrations. A taller blade with heel clearance adds comfort and control. The Mercer Millennia fits all of these criteria and does so at a budget-friendly price under $25, which makes it an easy recommendation whether it is your only serrated knife or a replacement for one that keeps tearing bread instead of slicing it.

Conclusion

The Mercer Culinary Millennia 10” Wide Wavy Edge Bread Knife earns its top spot by sticking to what works: pointed serrations, a sensible serration count, generous blade length and height, and a comfortable handle. At just under $25, it is one of the cheapest ways to complete your kitchen’s knife trifecta without compromising on performance.
