Chef's Knives
Egg Sizes
Kitchen culinary knives standardize blade lengths and edge geometry, centered around the 8-inch (20 cm) chef's knife. Edge angles distinguish acute Japanese bevels (15° per side / 30° inclusive) for push-cutting from durable Western/German bevels (20° per side / 40° inclusive) for rocking chops.
USDA egg sizing grades establish minimum net weight per dozen: Jumbo (30 oz / 850 g), Extra Large (27 oz / 765 g), Large (24 oz / 680 g — the standard 50 g baking benchmark), Medium (21 oz / 595 g), Small (18 oz / 510 g), and Peewee (15 oz / 425 g).
