Edge curvature |
|
The
design of the axe head, the curvature of the edge, the bevel
face, are adapted to its range of uses: Hardwood demands axes
with fairly thick bit, with rounded bevel face; but with softwood
cutting, the bit can be thinner; when limbing in frozen wood
(frozen wood is hard) the bit must be thicker, and the curvature
of the bit more rounded than cutting in non frozen wood; dry
wood cutting needs straight bevel face for a nice cut. Not only
the thickness of the bit is important for the strength; a rounded
curvature of the edge is stronger than a flat curvature.  1: For cutting hardwood 2: For cutting softwood 3: For cutting drywood. Angel 25º - 30º 4: Wrong grind! |
A: Curved bit. Forest Axe B: Straight edge. Carpenters Axe C: Wrong grind! |
