This specially
sharpened and honed flexible putty knife facilitates the clean and
efficient removal of gum tape after the veneer skin has been glued onto
the core or foundation. First, wet the surface of the tape for one or two
minutes, then push or scrape the layers of tape off the surface with the
knife. Any glue residue left on the veneer from the gum tape will be
removed in this way.
