Western Kitchen Knife Blade Edges
Different blade edges for different uses
Below are the four most common blade edges found on kitchen cutlery:
A Western straight edge blade, also called a Sabre grind, is formed by grinding both sides of the blade so that it tapers down into a “V” like point.
This type of edge is perfect for making clean and firm cuts without tearing the fibers in raw meat, vegetables and fruit.
A serrated edge blade has rows of teeth along the blade edge which are designed to easily penetrate a product’s tough outer crust, much like a saw, to prevent the soft inner flesh from tearing and protect the actual cutting edge from being dulled by the cutting board.
Serrated knives are great for cutting crusty bread, large tomatoes and cooked meats.
These dished out grooves creates air pockets between the blade and turgid foods such as fruit and vegetables which in theory releases food from the knife’s blade during the process of cutting.
A hollow ground edge is most effective for prep work, e.g., skinning fish, cutting sushi or peeling and slicing fruits rather than heavy cutting tasks.
Kitchen knife blade shapes
Kitchen knife blade configurations:
- Curved upward
- Curved downward
This type of blade is the reverse of the curved up blade, i.e., the spine curves downward to meet a blade that is straight from its tip back to the handle for the purpose of lifting the knife off the cutting board for chopping down.
Thus type of knife blade configuration is curved upward from the middle of the knife to the blade’s tip to meet a flat or straight spine (the top portion of the knife that runs from the handle to the end of the blade) which allows for a rocking force to its tapering point for chopping without the knife leaving the cutting board.
Curved up is where the spine and blade curve equally to meet one another at its tip. A good example is this type of blade configuration can be found on the standard utility or all-purpose knife or a petty knife
