RE: knife making
Having worked with furnaces and vehicles springs for many years the basics of heat treatment are quite simple, what is is difficult is getting even temperatures along the whole item.

A forge works well with a short blade, knife of spear head, but a bow would need a furnace chamber to get an even temperature otherwise you could not get an even temper, one end would bend/flex more than the other.

EN45 silicon manganese spring steel hardens at 850C, oil quench then temper at 650C and allow to cool, good luck.
