## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application is related to and claims priority from prior provisional application Ser. No. 60/693,197, filed Jun. 23, 2005, entitled “SCRAPING TOOL SYSTEMS”, the contents of which are incorporated herein by this reference and are not admitted to be prior art with respect to the present invention by the mention in this cross-reference section.
