A pruning saw blade disinfecting assembly comprising a cylinder with a removable lid at an open end. The other end of the cylinder is closed. A slit or other opening is provided at the top of the lid to allow the pruning saw blade to be inserted therethrough and into the interior area of the cylinder. The cylinder is preferably filled with a disinfecting solution. When the saw blade is inserted into the tube through the slit opening in the top of the removable lid, the saw blade comes into contact with the disinfecting solution. In a proper insertion position, the handle of the pruning saw remains on the outside and a significant majority of the blade portion of the pruning saw is submerged within the disinfecting solution. After it has been submerged for a sufficient period of time, the saw is pulled out and is ready for use.
