I'm new to hand saws, in fact the only ones I have are hack saws.
A few weeks ago I passed on a couple of Keystone back saws at the flea market. Mainly because about a third of the teeth were smashed flat. Looked like someone was banging on the edge with a hammer.
When is it worth it to have a saw reground, and how much does it cost?
I'd be happy to learn how to sharpen a heavily worn blade, but filing it down and starting from nothing is beyond my level of patience.
Is a Keystone worth it, or maybe only a good Disston?
