In detail the structure shown in Figs. 1 to 4
comprises the plastic body I of the pencil sharp

into the body. The beveled blade 3 is counter
sunk into the top of the body and overhangs and
extends into the hole 2 and is fastened by the
screw 4 threaded into the body I, the screw head
being below the plane of the top of the body.
The apex of the hole 2 is enlarged as at 5, to clear

in operative position, as in Fig. 1.
In this position the receptacle will catch and
retain all the waste incidental to the sharpening
operation. The receptacle can be easily removed
by holding the body I between the thumb and
fore?nger of one hand and pressing the thumb
against the front end of the dome portion at IT,
until an opening occurs between the edges I2, I3
and the end of the body I, through which the
contents of the receptacle can be shaken out,
without entirely removing the receptacle from
the body.
The receptacle is preferably composed of a
molded transparent plastic that will disclose the
contents of the receptacle. The body I and the
receptacle may be made in contrasting colors for
the exposed center lead of the wooden pencil, to
prevent breakage by the lead jamming in the
tapered hole when the pencil is forced longitudi
