This tool was developed by a flooring contractor over a long period of testing and improving. Extra weight is concentrated down by the 2″ wide double-ended reversible scraping blade. The blade need not leave the floor while working from a comfortable standing position. The blade can be sharpened with a file. Designed primarily for use on concrete subfloors, this tool can be used on wood subfloors too. It can also be used to remove sheet vinyl. Overall length is 50″ and weighs 14-1/4 lbs.
