Something I am always asked for are the saw filing templates in PDF form that I made for my backsaw project. They're the ones that are just lines on a page showing an angle to file a saw at or lines showing ppi to aid in cutting new teeth, like in this shot:
There were a few sizes missing - I made some additional templates to cover more sizes and angles, hopefully these will help you out.
I've compiled them all into one document and put them here:
Saw filing templates
They are all in PDF format - if you plot them without scaling them to fit the page (no scaling, in other words), they should print to scale properly.
EDIT: For those daring types, here's a pair of progressive pitch templates, one for 6 ppi - 9 ppi Toe to Heel on a 9" (22.86cm) blade similar to Lie-Nielsen and another that is 7 – 13 PPI over 14” similar to their progressive-pitch filed tenon saw...

Have fun filing!
