‘EXTREME Makeover: Home Edition” carpenter Ed Sanders needed some emergency repairs of his own after nearly chopping his hand off last Saturday.

Sanders was helping renovate the home of 9/11 hero Jason Thomas outside of Columbus, Ohio when he slipped – putting his left hand through an electric saw blade and slicing through his palm.

Sanders was rushed to a nearby hospital and underwent four hours of surgery to repair his hand, according to The Columbus Dispatch.

“It took a massive load of meat out of my hand,” Sanders told the newspaper. “I was sure my carpentry and acting careers were done.”

A show spokesman said the incident will be featured on the show when it airs early next year.

Thomas, a married father of five, was an ex-Marine living in Hempstead on 9/11 when he rushed to Ground Zero and helped save two Port Authority cops, whose story inspired the Oliver Stone movie, “World Trade Center.”
