The method of cutting laces according to my
invention comprises formingean aperture inside
the outer periphery of a piece of material and
cutting the lace spirally outwards from the centre
The lace cutter according to this invention may
be used to cut laces in the conventional manner
by adjusting the plate 1 to accommodate the ma
terial to be cut and adjusting .the cutter blade H
with respect to the bottom 4 of the slot so as to
obtain lace of the desired width. The edge of the
material from which the laces are to be cut is
then placed in the slot and a short strip cut by
the cutter blade. The end of this strip is then
grasped by the ?ngers of one hand and pulled
in one direction while the tool is held by the other
of the material in a uniform strip.
The above and other novel features of the in
vention will hereinafter appear in detail in the
description that follows, and are illustrated in

A short lace about half an
inch in length is cut by the cutter blade i I along
the periphery of the opening l9 by moving the
lace cutter in a clockwise direction.
The short
lace is then pulled outwards from the lace cutter
with the right hand while the lace cutter is kept 10
stationary with the left hand.
By pulling the
initially short lace, a lace 2| of increasing length
is cut spirally outwards from the opening I!)
while the piece of material 20 moves past the
cutter blade in a counterclockwise spiral path;
this can be continued in an uninterrupted opera
tion until substantially all of the piece of mate
rial 20 is converted into an unbroken lace of uni
form width. The outer edge !8 of the cutter
blade can then be used for cutting the lace into
desired lengths.

side, and a cutter blade extending transversely
of the slot and adjustably spaced with respect to
the bottom of the slot.
2. A lace cutter comprising a handle, a body
