I've used them on crosscut saw Rakers, like you would use an anvil for cutters. because they are tapered, you slide the bar into the gullet and use the adjoining cutter tooth as part of a backstop for the bar. The round part of the bar will help you from making a sharp bend under the Raker tooth. They are also used to swage the tooth of circle and band saw teeth also, except the tooth is hammered so as the tooth will be wider than the saw plate. different size bars for different size gullets.Jim_Thode wroteCOLONDisston says that the swage bar is for use on circular and gang saws. I guess that you could use it on a crosscut saw for swaging too. Some filers use a bar rather then hammering directly on the raker tooth.dayle1960 wroteCOLONSwage bars? Good grief, something else for me to dive into. Got an explanation on what a bar is used for, since I am so dense and lazy to research it myself. Honestly, this is the first time I've seen one and I ain't got a clue what it's purpose might be.
Maybe John can say exactly how he would use it.
