Serrated & Bread Knife

Teeth are what make this knife work, and they work by pressure. Each point concentrates your whole downward force onto a tiny area, so it punches through a hard crust or a tomato skin at a load a straight edge would have to squash its way past. Between the points, the ground hollows do the slicing as the blade draws back. Cutting happens on the stroke rather than on the push, which is why a loaf comes out in slices instead of squares.

Serrations come in two patterns and they behave differently. Pointed teeth bite hard crust fast and tear soft crumb on the way out. Scalloped teeth, meaning wide rounded waves rather than sharp triangles, cut cleaner through sandwich bread and layer cake and take longer on a sourdough crust. Length does the rest, as 9 to 10 inches crosses a round loaf in one pass where a 7 inch blade forces you to saw back and forth. Some blades set the handle above the edge, called an offset, which keeps knuckles clear on a flat board.

Nothing else in the drawer substitutes. A chef's knife has to press to cut, and pressing compresses a loaf before the edge gets through. So a fresh baguette flattens under one. Micro serrated utility knives, sold as tomato knives at 5 to 6 inches, do a slice of the job and no more. A long straight carving knife handles roast meat, where these teeth would shred it. Beyond bread, this blade is what opens a pineapple, a melon rind, a butternut skin and a frozen loaf without an argument.

Households buying crusty bread weekly, anyone who bakes and anyone who frosts a cake all need one, and so does a kitchen full of soft summer fruit. Cheap is really fine, since 20 to 40 dollars buys a stamped blade that lasts five to ten years with nothing to sharpen in between. Pass only if you buy bread pre sliced and never cut a tomato. Left handed cooks should study the grind, because many serrated blades are ground on one side and steer toward the other.

Judge the teeth for evenness, since a pattern ground unevenly catches and drags by the third slice. Stamped construction is correct here and costs less, as forging adds nothing to a saw. Never press or pry with it, because a chipped off tooth leaves a gap you feel in every loaf afterward. Brush crumbs out from between the scallops rather than soaking, and slide it into a guard so the points do not knock against other blades. Once it finally dulls, replacing it usually costs less than the grinding service that could restore it.
