A current thread comparing old saw with new boutique saws reminded me I have no knowledge regarding the use of handsaws. I have plans to start making some boxes and picture frames. I would like to have a nice saw to cut the dovetails and possibly making 45° crosscuts for picture frames. What kind of saw would do both those jobs? I thought I would want a backsaw but it seems there's all kinds of names for saws. Without knowing what I should be looking for I thought I'd ask the collective brain trust here. I prefer vintage tools and am frankly too cheap to buy boutique tools. I'd even ask what brands are considered best. From reading here I'd guess old Disston and Atkins are good but how old? Are these similar to Stanley planes where the quality started to suffer after WWII? Is there a sweet spot of dates on these old saws I should be looking for? Thanks for any and all thoughts/info!
