Panther handle and file guides are only available in 5/32″[4mm], 3/16″[4.8mm], 7/32″[5.5mm]. Good price and not really any different from the other offerings..
Group 4 (and 5) – what does that mean? Generally the saws that run 3/8 are Group 4 saws.
How do I know which Group my saw is in? There is a list in the pipeline coming!
