配方组成：
配制方法：	Tools with plastic handles often become useless due to the tool shank turning or otherwise loosening. The handles can be tightened as follows: Remove the tool form the handle. Fill up the tool hole in the handle with powdered rosin. Now heat the tool shank to near cherry red and insert it into the rosin-filled hole. Let the tool gradually cool. In a few hours, the tool will be as firmly imbedded as it was originally.
