5 or 6 Inches? The Best Kitchen Utility Knife for Daily Prep

A utility knife is the size between a paring knife and a chef’s knife, usually 5 to 6 inches. It is the knife you reach for when a chef’s knife feels like too much and a paring knife runs out of blade: halving limes, slicing a jalapeño, trimming a chicken thigh, cutting a torta in two.

You do not strictly need one, but once you have one, it tends to stay on the board. This guide compares eight utility knives from established makers, forged and stamped, straight and serrated, German and Japanese. These are kitchen knives, not the box cutters that share the name.

Our picks for the best kitchen utility knife

The picks run from the best all-round choice to the more specialized knives. Each one comes from a maker with a long record in cutlery, and each was in stock when we checked.

How to choose a utility knife for your kitchen

Length. A 6-inch blade reaches across a tomato or a sandwich. A 5-inch blade feels nimbler and suits smaller hands. If your paring knife is on the long side, a 6-inch fills the gap better. If your chef’s knife is a short 7-inch, a 5-inch does.

Straight or serrated. A straight edge is the better all-round choice. It slices herbs cleanly, trims meat and can be kept keen with a honing steel. A serrated edge handles tomatoes, bolillos and salami with little pressure, but it tears soft greens and is hard to sharpen at home.

Blade height. Many utility knives are slim, which means your knuckles meet the board on a downward cut. ATK singled out a tall heel as a key feature in the knife it preferred. If you chop more than you slice, look for a taller blade.

Forged or stamped. Forged knives have more weight at the bolster and feel solid. Stamped knives are lighter and easier to sharpen along the whole edge. Neither is automatically better, so choose by how you like a knife to feel.

German or Japanese steel. German-style knives tend to use softer steel and thicker edges, so they forgive rough use and touch up easily. Japanese knives such as the Shun and Tojiro use harder core steel and thinner edges. They cut with less effort but need more care.

Care. Most makers here ask for hand washing. Dry the knife right away and store it in a block, on a strip or in a guard. Use a wood or plastic cutting board, since glass and stone dull an edge quickly.

How we picked these eight utility knives

We did not use these knives ourselves. We started with the 5- to 6-inch range and kept only knives their makers sell as utility knives, plus one serrated prep knife that America’s Test Kitchen reviewed as a serrated utility knife. Paring knives, mini chef’s knives and box cutters were left out.

Specifications come from the makers’ Amazon listings. Independent evidence is limited. ATK’s 2020 serrated utility knife test is the one rigorous review we could find, and it covers serrated knives only. We found no comparable test of straight-edge utility knives, so those picks rest on maker specifications, construction and each maker’s long record. We left out newer online-only brands with no independent review, because a sharp knife is not the place to take a chance on an unknown name.

We also searched the U.S. Consumer Product Safety Commission recall database by brand on October 31, 2026. It showed no recall of a knife from Wüsthof, Mercer, Henckels, Zwilling, Shun, Tojiro or Global. The one result for these makers is a May 2026 Zwilling recall of Enfinigy electric kettles, which does not involve knives.

Utility knife questions, answered

What is a utility knife used for in the kitchen?

It handles jobs too big for a paring knife and too small for a chef’s knife, such as slicing shallots, cutting citrus, trimming small cuts of meat and cutting sandwiches.

Is a utility knife the same as a petty knife?

Close to it. Petty is the Japanese word for this size of knife, borrowed from the French word for small. A petty usually has a thinner, harder blade than a German utility knife, but it does the same jobs.

Do I need a utility knife if I own a chef’s knife and a paring knife?

Need, no. Many cooks manage well with those two. A utility knife is a comfort on small jobs, and it is often the knife people reach for when making a quick snack or lunch.

Should a utility knife be serrated?

Choose straight first if you are buying one. Add a serrated knife if you often slice tomatoes, rolls or salami and do not want to reach for a long bread knife.

Can a utility knife go in the dishwasher?

Follow the maker. The Henckels and Zwilling listings here allow it, while Wüsthof and Mercer ask for hand washing. Hand washing is better for any edge.

Our final pick for everyday prep

For most kitchens, the best kitchen utility knife is the Wüsthof Classic 6-inch: a straight, forged blade that covers the small jobs a chef’s knife does not. Add the Zwilling Pro serrated knife if tomatoes and tortas are a regular part of your week.
