This ?inventionfrelates to scissors and shears
Sharpeners, and the chief object of the invention
is to provide simple, ellicient and practical means
for sharpening such implements, and that may be
easily and readily used and operated by individ
uals, even though not expert in such work.
A further object of the invention is to provide
a scissors and shears Sharpener including a flat
and horizontally disposed table, means at the
rear end of the table for releasably engaging a
blade of a pair of scissors or shears and support
ing the blade in proper position relative to the
`table for bevel sharpening the same, and a ñle
with means on the handle thereof for slidably

from the rear end of the table 5 and similar ears
I2 are turned inwardly from the lower margin of
the inner clamp-plate 8 and adapted to overlle
the ears II of the table 5. A pivot bolt I3 is
passed through the two sets of overlying ears II
and I2, whereby the clamp-plates ‘I and 8 are
pivotally supported at the rear end of the table 5
