The Large Block Plane Holders are made to fit most commonly available large block planes, both new and vintage versions. They have overall dimensions of 8.5" tall, 3.25" wide, and 1.5" deep, allowing them to fit just about anywhere. Designed to be mounted on a vertical surface such as a shop wall, inside a tool chest, or on the side of a workbench, each Holder has three holes for secure mounting with brass screws (included). The Holders are made of 8-10oz. Vegetable tanned Bridle leather that has been wet moulded for an exceptional fit. The Standard Block Plane Holster was designed around the popular Stanley 65 and 60-1/2 block planes, but will fit most planes that are of similar dimensions, generally 2" wide or less. The Rabbeting Block Plane Holster is specifically designed to fit the Lie-Nielsen Rabbeting Block Plane. The bottom of the plane holsters are left open to allow for wood shavings, dust, and debris to pass through. That kind of detritus can absorb ambient moisture, increasing the chances of corrosion and rust if allowed to contact your block plane. By allowing that to pass through, the chance of corrosion and rust drops significantly. The hole in the bottom also makes maintenance much easier. You can pass an oil soaked rag right through the holster, applying oil to all contact areas with ease. Oiled leather is better at repelling ambient moisture. Less moisture equals less corrosion! We recommend lightly oiling the leather once every few months, more in extreme conditions. Standard leather oils such as Neatsfoot Oil work just fine. These holders are available in Chestnut, Golden Brown, and Black.
