Kitchen Knives: The Secret of Those DimplesWhy some blades have indentations on their sides.

Why it looks like that

Ever wondered about the oval dimples on the side of a knife? It’s a specific design feature that creates tiny air pockets between the blade and the food you’re slicing. This clever engineering reduces suction and friction, allowing for cleaner, more uniform slices. This is especially helpful with moist or starchy foods like potatoes, cucumbers, or raw meat. It's fluid dynamics at work in your kitchen.
