The bucket opener opens and re-seals 2-5 gallon plastic pails. There is no need to use a cutting device when opening pails with the bucket opener. Simply place the upper hook under the rim of the lid and push down on the handle. Continue this action around the rim and pull the lid off. Re-seal the lid by using the built-in hammer. Great for homeowners, deli's, dry wall, printers, supermarkets, painters, contractors, and many more.
