Short verdict: A chef’s knife is the longer, heavier, curved-belly workhorse for rocking cuts and larger prep. A santoku is shorter, lighter, and flatter-edged for push cuts, slicing, and precise vegetable work. If you rock-chop constantly, go chef’s. If you prefer a nimble smaller blade, go santoku.
Key takeaways

- The exact santoku models in this comparison cover 5-inch and 7-inch blades.
- Several supplied santoku models use hollow or grooved edges to reduce food sticking.

Dimension-by-dimension tradeoffs
Blade length
A chef’s knife is typically longer, which helps with large cuts but takes more room. Santoku models in this comparison are 5 or 7 inches. The 7-inch models are a practical all-purpose size for home kitchens; the OXO 5-inch is more compact and easier to store or transport.
Edge shape and cutting motion
The biggest functional difference is edge profile. Chef’s knives have more curve, or belly, so you can rock the blade through herbs and dense produce. Santoku knives have a flatter edge and less belly, favoring push cuts and up-down chopping. The OXO model explicitly has a straight edge and rounded non-pointed tip, which supports consistent thin slicing.
Blade thickness and edge geometry
Santoku knives are often thinner and more precise. In the supplied records, the imarku is described as 2.5mm thick with a 15-18 degree per side edge. The Mercer is described as a 16 degree edge on both sides. The HOSHANHO claims 62HRC hardness and a 15 degree hand-sharpened angle. The QEGNOBOK is described as 0.08 inch thick with a 15-18 degree per side edge. These specifications support the santoku’s lighter, thinner cutting character compared with many heavier chef’s knives.
Weight and grip
Chef’s knives tend to feel heavier and more forward-weighted, which helps with rocking but can be tiring for smaller hands. Santoku knives are generally lighter. Handles also differ: Mercer uses a slip-resistant Santoprene handle; imarku and HOSHANHO use pakkawood; OXO uses a soft non-slip grip; QEGNOBOK uses an ABS handle. Choose a handle that feels secure when wet.
Food release
Several santoku models here add texture to the blade: imarku and QEGNOBOK have hollow/scalloped edges, and HOSHANHO has a double-side groove design. The stated purpose is to create a gap between blade and food to reduce sticking during slicing, dicing, and mincing.
Care and storage
Mercer’s supplied description recommends hand washing, rinsing, and drying completely. OXO includes a locking sheath for blade protection and transport. High-carbon stainless steels in the imarku and QEGNOBOK models are described as resisting rust, corrosion, and discoloration, but hand washing is still common for edge retention.

FAQ
Is a santoku just a shorter chef’s knife?
No. A santoku has a different edge profile, usually less belly, and often a rounded or less pointed tip. Those shape differences change the cutting motion from rocking to push cuts and up-down chopping.
Can a santoku replace a chef’s knife?
For many home cooks, yes. A 7-inch santoku can handle slicing, dicing, and mincing. If you regularly rock-chop herbs or break down large cuts, a chef’s knife may still be more comfortable.
What size santoku is best?
7-inch models are the common all-purpose size in this comparison. A 5-inch model, like the OXO, is better for compact storage, small prep areas, or travel.
Do hollow-edge blades really help with food sticking?
Manufacturer descriptions for the imarku and QEGNOBOK models say the scalloped hollow edge creates a gap between blade and food to keep food from sticking. The HOSHANHO uses a double-side groove for a similar purpose.
Should I buy both a chef’s knife and a santoku?
Not necessarily. If you already have a chef’s knife and like it, you may not need a santoku. If you want a lighter, flatter blade for vegetables and precise slices, a santoku is a useful addition.
