Hans Karlsson 150-45 dogleg gouge
The dogleg gouge is designed to reach into the hollowed bottom of carved bowls or other sculptural applications. Hand forged from Swedish ball bearing steel to really hold a keen edge.
The sweep & size are indicated by the curve of a circle measured in millimeters - the first number is the sweep, a large number means a flatter gouge. The second number is the width of the blade. (So the 150-45 is the flattest, widest gouge and the 55-30 is the most curved, narrowest gouge.)
