The scraping tool 6 may be made from any fairly rigid
or stiif material such as plastic or metal, for example, and
is small and light in weight so that it can be readily car~
ried in one’s pocket. A ‘hole 24 is also provided in the
end of the handle 8 to enable the tool ‘6 to be carried on
larly to a tool for scraping the corrugated sole of a shoe

with the vertical legs 30 projecting upwardly through a
conventional door mat 38, or the like. Spacers 42 may
be disposed between each of the vertical legs to accurately
space the scraping devices 28. With this construction,
