For woodworking hand tools, the grain of the steel is the most important characteristic of a blade. Ordered, repetitive arrangements of iron and alloy atoms in a crystalline structure comprise steel. The crystals can be small and fine or large and coarse. They can be consistent in size (evenly grained) or vary widely, with odd shapes and outsized clusters in among the rest. The steel’s grain affects how finely the blade sharpens and how quickly it dulls. Generally, the finer and more consistent the grain, the more finely a blade sharpens, the slower it dulls, and the better it performs.
