We have reproduced one of the most sought-after saw tools ever manufactured! The jointing process brings all the cutting teeth on the saw even with the arc of the saw. When all cutting teeth are made to touch this arc, all the cutting teeth will cut. This is part of the efficiency of cutting – getting more chips per stroke. Unless the saw is jointed properly, only a few teeth are actually cutting – the rest are just along for the ride.
The long jointer is designed specifically for one purpose – jointing a two man saw. Superior results can be achieved over a short jointer / raker gage tool for this purpose. The reason is that the long jointer guarantees a round saw. The two ski-like shoes and the file ride along the true arc of the saw. These three points represent the arc, and continue this same arc along all the cutting teeth on the saw. This guaranteed roundness results in the smoothest cutting possible!.
Glass-hard shoes are adjustable in height to conform to the arc of any crosscut saw. Solid bronze tool has brass wingnuts – no tools required. Complete with special long jointer jointing file. Considered indispensable when filing competition saws. A really hard-to-find saw tool that every professional filer should have, as well as anyone who is interested in cutting wood at optimum efficiency with a two man saw.
