A chef knife and a santoku can both handle vegetables, herbs and boneless proteins. The difference is less about a list of foods and more about how each profile moves through them.
The chef knife profile
The 8-inch chef knife has a longer blade and a more pronounced curve toward the tip. That curve supports rocking cuts: the tip can stay close to the board while the heel rises and falls. Its length is useful for larger ingredients and long slices.
Choose it if you enjoy an all-purpose blade, regularly prepare larger produce or naturally use a rocking motion for herbs and mixed chopping.
The santoku profile
The 7-inch santoku is shorter, with a straighter cutting edge and lower tip. It is comfortable with forward-and-down push cuts and repeated vertical chopping. Many cooks find the compact length easy to control in smaller kitchens.
Choose it if vegetable preparation dominates your routine, you prefer a flatter cutting path or an 8-inch blade feels larger than necessary.
How they feel different
- Length: the chef knife provides more edge for large ingredients; the santoku feels more compact.
- Motion: the chef profile encourages rocking; the santoku encourages push cutting and chopping.
- Tip: the chef knife has a pointed tip for controlled tip work; the santoku tip is lower and less prominent.
- Board space: the santoku is convenient on a compact board; the chef knife benefits from a little more room.
Which one should you buy first?
Choose the 8-Inch Chef Knife if you want the broadest single-knife versatility and do not mind the additional length. Choose the 7-Inch Santoku Knife if your cooking is vegetable-heavy and you favour a compact, straighter cutting path.
If your household cooks often or two people prepare food together, owning both is not redundant. Their overlap lets each person choose the motion that feels natural, while the differences make each useful for particular batches of prep.
A safe test at home
Whichever profile you use, place the cutting board on a stable surface, form a relaxed claw with the supporting hand and start slowly. The right knife should feel predictable. If you need excessive force, stop and check the edge, the ingredient and whether a different profile would suit the task better.
