Uh oh, I think I may have gone too negative on my first post. My apologies. The Curtis saw company made very good saws back "in the day". Their modern saws (or whoever is making them with the Curtis brand) are not the same tool. I have filed a lot of crosscut saws and counseled new sawyers on good ones to buy. There are plenty of good saws still available if you look. NGOs and certain US agencies typically don't buy tools on Ebay, so they purchase what's available in the retail marketplace, which is to say, not much. Those "new" saws then make their way into tool rooms, and if not intercepted by a decent filer, are misery whips out of the box.
