The Grammercy mentioned has a hang angle of approx. 45*, The Lie Nielsen approx. 40*, Bad Axe approx. 30* The higher the hang angle the more aggressive the saw will be, given the same pitch, rake and fleam ( Fleam should be 0 ). Mine are 45*, 38*, and 32*. Depends on what mood I am in. The vintage saws vary quite a bit as well. If you get the opportunity, try different saws to get a better feel for what works for you. Happy hunting.
