Cleaver

Lore & Background

The cleaver is designed with a tough edge meant to withstand repeated blows into thick meat, cartilage, bone, and cutting boards. This resilience comes from using a softer, tougher steel and a thicker blade, as harder steel or thinner blades might fracture. In use, it is swung like a hammer, relying on momentum from the user's swing and the cleaver's weight. Contrary to some older notions, a modern kitchen cleaver benefits from a sharp edge—typically honed to a keen, durable finish—which allows for cleaner cuts through meat and soft bones. The grind for a meat cleaver is approximately 25°, which is indeed more obtuse than many other kitchen knives, but this does not mean the edge is dull; it is simply less acute to avoid chipping. Some cleavers have a small hole at the top front corner for hanging, as butchers typically do not lay them flat to avoid dulling or damage. Cleavers are primarily used for cutting through thin or soft bones and sinew, such as chopping through a chicken's thin bones or separating ribs. They can also prepare hard vegetables like squash, where thin slicing blades might shatter. Cleavers are not used for solid, thick, hard bones; a bone saw is used instead. In Chinese thought, a story from the Zhuangzi tells of a butcher (Cook Ding) who effortlessly cut ox carcasses without sharpening his cleaver, by cutting in the space between bones. The remark 'Why is that so?' is not from that story but from a later Chinese proverb, and Confucius is not the speaker in the Zhuangzi context.

Reader's Guide

The cleaver's significance lies in its specialized design for heavy-duty chopping, distinct from other kitchen knives. Its tough, thick blade and blunt edge allow it to withstand repeated impacts that would damage thinner or harder blades. This makes it essential for butchers and cooks who need to split soft bones and dense cartilage efficiently. The cleaver's cultural resonance appears in traditional Chinese thought, where it symbolizes skill and proper technique, as in the Zhuangzi story of a butcher who never sharpens his blade by cutting between bones. Confucius used the cleaver metaphorically to critique misplaced ambition. The cleaver's legacy includes its influence on East Asian cutlery: the Chinese chef's knife is often mislabeled a 'cleaver' due to its rectangular shape, though it is thinner and used for general slicing, while a heavier Chinese version serves a similar role to the Western cleaver. In Japan, the deba bōchō fills a similar light-duty role for cutting fish heads. The cleaver remains a practical tool for specific tasks, not a universal knife, and its design principles—soft steel, thick blade, blunt edge—continue to inform modern butchery tools.

Did You Know?

• The cleaver's edge is ground at a relatively obtuse angle (around 25°) for durability, but modern kitchen cleavers are kept sharp to cut cleanly through meat and soft bones.
• While heavy chopping tools date back to the Stone Age, the specific design of the kitchen cleaver as we know it is a much later development.
• In the late 17th century, 'cleaver' was commonly spelled 'clever'.
• A cleaver is not used for cutting through solid, thick, hard bones; a bone saw is used instead.
