Reviving his thread. I too have used both Excaliber and Tuff Saws and much prefer the latter.
But I have just put my last Tuff Saws 93" X ¼" 6 skip blade on my Startrite 301S and want to order 2 more. All I can find in the M42 ¼" blades are 2 Vari-Tooth and no 6 skip? I contacted Ian and he told me that there are all sorts of problems getting the saw band types, BUT he managed to find some ¼" 6 skip and is making up a couple of blades for me!
Now that is what I call service and a HUGE thank you Ian!
