There are three basic types of axes: single bit, double bit, and smaller axes referred to as “boys axes,” "camp axes, or “cruisers."
The single bit axe used for felling or splitting usually has a 3-5 lb axe blade and a 30”-36” inch curved handle.
A double bit axe can either have two identical blade types so that one can be used after the other becomes dull from use or can have two different types of blades. Some double bit axes have a very sharp felling blade and a second blade which can be either blunter for cutting knots or more wedge shaped for splitting The double bit axe usually has a 3-5 lb blade and a 32” – 36” straight handle. Smaller double bit axes (2-4 lbs.) are referred to as "cruisers."
Boy’s axes are significantly smaller than the single bit or double bit axes. A specialized axe in this category is the Hudson’s Bay axe. These axes are usually in the 2 - 2.5 lb. range with a 24" - 28” inch handle.
