Buying Guide

Blade Material and Sharpness

The blade material determines how long the knife stays sharp and how easy it is to maintain. High-carbon steel is a preferred choice because it holds a keen edge and resists corrosion. The Mercer Culinary M23210 uses Japanese high-carbon steel, which offers a balance of hardness and flexibility for precise slicing.

A serrated knife relies on its scalloped teeth to grip and cut through tough exteriors. Look for a blade that is forged from a single piece of steel for durability. This construction prevents the blade from loosening over time, ensuring consistent performance.

Ergonomics and Grip

Comfort during extended use is critical, especially when slicing multiple loaves or large fruits. An ergonomic handle with a non-slip texture reduces hand fatigue and improves safety. The Mercer Culinary Millennia series features a textured finger point design on the handle, providing a secure grip even when hands are wet or greasy.

A well-balanced knife also enhances control. A full tang, where the blade extends through the handle, improves balance and stability. For more on knife ergonomics, see our guide to top kitchen knife sets.

Blade Length and Versatility

A 10-inch blade is the standard length for a serrated bread knife. It is long enough to slice through large loaves, cakes, and even watermelons. The wide wavy edge on the Mercer knife allows you to cut through crusts and skins without tearing the soft interior, making it ideal for bread, angel food cake, meatloaf, fruits, and tomatoes.

Versatility matters if you want one knife for multiple tasks. While primarily a bread knife, a good serrated blade can handle delicate items like tomatoes and citrus with ease. For a different cutting style, read our review of the best santoku knife.

Ease of Maintenance

Serrated knives require special care to keep their teeth sharp. Hand washing with mild soap and warm water is recommended to prevent damage. Dishwashers can dull the blade and degrade the handle material over time. The Mercer knife is designed for easy maintenance, and with proper care, it will last for years.

Regular honing is not necessary for serrated blades, but occasional professional sharpening can extend the knife’s life. For more kitchen tips, explore the Kitchen category.
