Serrated vs Hollow Edge Comparison
Edge Type
The Imarku set features a serrated edge, which is ideal for sawing through crusty bread or tomatoes without crushing the interior. This geometry uses teeth to grip slippery surfaces. In contrast, the Mercer Culinary Millennia uses a Granton edge, listed as a hollow edge style. These hollows create air pockets that reduce friction and prevent food from sticking to the blade. While serrated edges excel at tearing through tough skins, the hollow edge design is optimized for slicing soft or sticky items like meat and vegetables with minimal resistance. You choose based on whether you prioritize grip or glide.
Blade Material
Imarku constructs its Gyutou knives from high carbon stainless steel, which offers a balance of sharpness and rust resistance. This material is durable and suitable for general kitchen tasks. The Mercer Culinary Millennia uses high-carbon Japanese steel. This specific alloy is known for taking a very fine, razor-like edge and holding it well during heavy use. Japanese high-carbon steel often requires more careful maintenance to prevent corrosion compared to stainless variants. If you prefer low maintenance, the stainless steel in the Imarku set is practical. If you want maximum sharpness potential and do not mind care, the Mercer steel is superior.
Construction
The Imarku knives are precision-forged, a process that aligns the metal grains for strength and durability. This method typically results in a robust blade capable of handling various chopping tasks. The Mercer Culinary Millennia is crafted as a one-piece knife. This means the blade and handle are formed from a single piece of steel, eliminating weak points where the blade meets the handle. One-piece construction is often favored in professional kitchens for its longevity and ease of cleaning, as there are no seams to trap food. For long-term durability and structural integrity, the one-piece design of the Mercer knife has a clear advantage.
Everyday Use
The Imarku set is a complete 14-piece collection that includes a chef knife, bread knife, Santoku, utility, paring knives, and steak knives. It also comes with a hardwood block and built-in sharpener, making it a comprehensive solution for a full kitchen. The Mercer product is a single 7-inch Santoku knife. It is designed specifically for chopping, mincing, and dicing tasks like onions, herbs, and garlic. If you need to equip an entire kitchen, the Imarku set provides all the necessary tools. If you already have a set and need a specialized tool for precise prep work, the single Mercer knife is the focused choice.
Blade Profile
The Imarku Gyutou knife features a 10–15 degree edge angle. This acute angle allows for very precise slicing and chopping, delivering clean cuts that are often preferred in Japanese-style cooking. The Mercer Culinary Millennia is a 7-inch Santoku with a Granton edge profile. The hollows along the flat of the blade help lift food away from the surface. The Santoku profile is versatile for rocking cuts and push cuts. The Gyutou is a general-purpose chef knife shape. The Imarku offers a sharper angle for precision, while the Mercer offers a specialized profile for reducing stickiness during slicing.

You need a complete set with storage
This Imarku set includes 14 pieces housed in a natural wood block. It features a built-in sharpener for quick maintenance.

The ergonomic handles reduce hand fatigue, making it suitable for extended prep sessions or users with limited hand strength.
You want a lightweight single Santoku knife
The Mercer Culinary Millennia is a single 7-inch Santoku knife weighing only 3.17 ounces. Its Granton edge creates air pockets to prevent food from sticking to the blade. The textured black handle provides a secure, non-slip grip. This design is optimized for chopping, mincing, and dicing tasks with minimal wrist strain.
You prefer a sharp, durable edge
Imarku uses high carbon stainless steel forged for a razor-sharp 10–15 degree edge. This acute angle stays sharp longer than standard blades. The construction is precision-forged for durability. While the Mercer offers a Granton edge, this set provides a sharper initial cut and includes multiple knife types for various kitchen tasks.

Frequently asked questions
What is the main difference between serrated and hollow edge knives?
Serrated knives use a toothed edge to grip and saw through hard crusts or soft skins without crushing the interior. Hollow edge knives, like Granton styles, feature indentations along the blade. These hollows create air pockets that reduce friction and prevent sticky foods like potatoes or meat from adhering to the steel surface.
Which edge type is better for cutting bread?
Serrated edges are superior for slicing bread. The teeth act like small saws, penetrating crusty exteriors cleanly while leaving the soft interior intact. Hollow edge blades excel at slicing meats or vegetables that tend to stick, but they lack the aggressive gripping power needed for tough bread crusts without potential tearing.
Do hollow edge knives stay sharper longer?
Hollow edge geometry itself does not inherently retain sharpness longer than a standard grind. However, the reduced surface area in the hollows can minimize drag during slicing. Maintenance depends on the steel type. High-carbon stainless steel, often used in these knives, offers good corrosion resistance and edge retention for daily prep tasks.
Are hollow edge knives harder to sharpen?
Sharpening hollow edge blades requires care to avoid damaging the indentations. You must maintain the original bevel angle while avoiding the hollowed sections. Serrated knives often need specialized rods or stones to reach the individual teeth. Both types benefit from regular honing to maintain their specific cutting performance and safety during use.
What is a Granton edge?
A Granton edge is a specific type of hollow edge. It features a series of small, oval depressions ground into the blade side. These indentions reduce suction and friction between the food and the knife. This design is common in Santoku knives and helps slice sticky ingredients like cheese or raw fish more easily.
Can I use a hollow edge knife for tomatoes?
Yes, you can use a hollow edge knife for tomatoes, but a serrated blade is often preferred. The teeth of a serrated knife grip the slippery skin without slipping. A hollow edge blade can slice through the skin if it is sharp enough, but it may crush the delicate flesh more easily than a sawing motion.
How do I clean a hollow edge knife?
Clean hollow edge knives by hand immediately after use. Food particles can get trapped in the hollows, leading to corrosion or bacterial growth. Use a soft brush or cloth to gently remove debris from the indentations. Avoid abrasive scrubbers that might damage the steel finish or alter the precise geometry of the edge.
