Greetings,
I haven't seen this answered in any of the great posts about saw rehab and sharpening- So I hope some of y'all can help.
At what point has a saw been sharpened past its useful life? When is it really not worth the time? When they've been sharpened past the TPI # stamped in the heel? (incidentally, did the Disstons all have this?). Is there a point where you're not going to get good results with the saw regardless of technique (in filing or sawing)? My Father-in-law picked up a bunch of old saws for me and I don't want to use up a good one learning to file, nor do I want to get frustrated trying to sharpen something that won't give good results regardless.
Here is a picture of a D23: the TPI (11) is right at the tooth line. I'd imagine that the main limitation is the proximity to the bottom of the handle, but is this one to let the kids practice sharpening on, or is it worth fixing up?

Here is a Disston 115. There are no numbers stamped in the heel. Is it wothwhile to send off to one of the saw docs or has the plate been used up?

This is assuming that all else that goes wrong with old saws is OK (no kinks, straight blade, no pitting).
-Thanks,
Peter
