Inserted Tooth Sawblade
The Saw in History - on Inserted Tooth Saws -
The hard part is "Hammering" a saw this is a process that is dependant on its gauge, its diameter and its intended speed - old timers can do it by some sixth sense (experience) me, I barely understand it... also keep in mind that a file, some punches, an abrasive stone, a hammer and vise where the usual toolset to maintain a saw up until fairly recent times ;-)

not really, (sooory!) It needs to be a specific grade of spring steel, a saw gets a LOT of dynamic loading while cutting and friction makes them heat up dramatically, the saw cuts VERY differently at different temperatures the heating can be asymmetric (one side rubbing in a sprung, timber bound cut (Timber bound is the internal stresses in a log being released - a 20,000 lb tree can have some massive stresses "Grown" into the wood you release them when you cut it) asymmetric heating causes the blade to "Cup" creates another source of stress and heating - its nothing to play with on a larger saw.
Q: Even the old time sawblades?
I THINK inserted teeth are typically forged, but you could probably anneal, mill and heat treat before grinding. Most modern inserted teeth are carbide however and I know next to nothing about fabbing that...

these are handy for the afore-mentioned high speed with band mills- given you cut a board on each pass of the carriage Bold text
