What Is a Utility Knife Used For?
The in-between knife — bigger than a paring knife, smaller than a chef's. Handy for small jobs, but the one most cooks can skip.

A kitchen utility knife is the mid-size blade — usually 4 to 7 inches — that sits between a big chef's knife and a little paring knife. It is essentially a small chef's knife, and it is handy for jobs that feel too small for a chef's knife but too big for a paring knife. Whether you actually need one is a fair question — so here is what it does and who it suits.
What a utility knife is good at
The utility knife shines on small-to-medium jobs on the board or in the hand:
- Slicing sandwiches, bagels and rolls
- Cutting a single tomato, a small onion, a lemon or a lime
- Trimming fat and sinew from meat, or topping and tailing vegetables
- Slicing cheese, cucumbers and small produce
- Any job where a chef's knife feels like too much blade and a paring knife too little
Its length makes it more nimble than a chef's knife for these small tasks while giving more control on a board than a paring knife. Some utility knives come with a lightly serrated edge, which makes them handy all-rounders for tomatoes and soft rolls.
Do you actually need one?
Honestly, for most cooks, no — and we would rather tell you that than sell you a knife. The reason is that a chef's knife and a paring knife togetheralready cover almost everything a utility knife does: the chef's knife handles anything on the board, and the paring knife handles small in-hand work. The utility knife falls into the gap between them, which means it is a convenient extra, not an essential. Buy the chef's knife first, add a paring knife second, and only add a utility knife if you find yourself reaching for something in between often. The full distinction from a paring knife is in paring knife vs utility knife, and from a chef's knife in chef knife vs utility knife.
If you do buy one
A utility knife does not need to be expensive — it is a supporting player, not the star. Look for a comfortable handle and a blade around 5 to 6 inches, and keep it sharp like any plain-edged knife (a lightly serrated one, like a bread knife, is best replaced when dull). It fits the same essential logic as the rest of the block: a few good knives you actually use beat a drawer full of specialty blades — the case we make on the sets page.
Questions
Frequently asked
What is a utility knife used for in the kitchen?
Small-to-medium jobs that fall between a chef's and a paring knife: sandwiches, single tomatoes, small onions, citrus, trimming meat, slicing cheese. It is a small, nimble all-rounder — essentially a mini chef's knife.
Do I need a utility knife?
Most cooks don't. A chef's knife and a paring knife already cover almost everything a utility knife does, so it is a convenient extra rather than an essential. Buy those two first; add a utility knife only if you often want something in between.
What's the difference between a utility knife and a paring knife?
A paring knife (3–4 in) is used in your hand off the board for peeling and detail work; a utility knife (4–7 in) is bigger and used on the board for small jobs. See paring knife vs utility knife.
