My adz attachment, as shown in the drawing,
consists essentially of ablade member I and a
simple means A for securing it to the head 2a of
the hammer 2.
The blade member is a relatively thin convexly 50
or outwardly curved plate of tool steel, relatively
wide at its lower end, providing the sharp or
cutting edge Ia of the tool, and relatively narrow
at its upper end. Intermediate these ends is an
opening or recess |° for receiving the striking por
Thus, the'clamp member may be readily
placed around the neck portion of the hammer
and the outer end of the leg 311 may be readily
inserted into the slot lg. The blade member is
clamped against the outer face of the head of the
45 handle by means of the adjustingscrew 5 which
extends through the connecting portion of the
U-shaped clamp member. This screw may be
readily adjusted with a wireor nail, usually car
ried by a carpenter who may use the tool.
It will be here noted that the legs of the clamp
member and also the link 4 are so shaped that
they may spring slightly when the blade member
is clamped into position.
The blade member I is so designed that it may
