In the form of the invention shown in FIGS. 1-3, a
grasping handle of suitable material such as the wood 50 to be made upon such ‘a stencil sheet by a relatively un
handle 10 is provided having a polygonal shape to position
the same within the writer’s ?ngers for proper operational
positioning of the stenciling tool. An elongated mounting
arm 12 is attached to the lower end of the handle 10 in
longitudinal alignment therewith, as by ?attening the upper
skilled person, without the danger of gouging 0r tearing
the stencil surface.
As in the form shown in FIGS. 4-6, a mounting stem 33
attached to a polygonal grasping handle at one end there

set forth in the appended claim.
What is claimed is:
A stencil marking device comprising an elongated
handle, a mounting member connected to the lower end U!
vof said handle and having a longitudinally extended por
tion, disposed at an obtuse [angle relative to the axis of said
handle, a stencil marking tool having a loop formed ‘at
the lower portion thereof and swivally mounted at the
outer end,_portion of said mounting member and disposed
normally to the extended portion thereof, the lower end of
a said tool having a stencil engagingvmarking element in the
form of Van arcuately curved member connected there
with and having the stencil engaging portion thereof dis~
posed in laterally o?set'relation to the swivel axis.
