Please, for the saftey of of yourself and you loved one's, do not use a 440 stainless sword to hit anything.
Stainless steel, for all of it's wonderful utilitarian uses, is damn near abhorrent for sword material. The chromium makes it too brittle. Even if used against a "soft" target, you run a disturbing risk of blade failure, especially given the likely heat treat (or lack there of) given the blade.
In sword construction, a craftsman is working with steel and trying to bring together two elements that, in general, are diamertrically opposed: toughness and hardness. Toughness allowes the sword some give, and allows for edge retention. Hardness is necessary to put an edge on it in the first place and to keep it from constant deformation.
Long and short, man cultures worked many years on this, all with fascinating results.
Stainless steel is great for knife blades, but it's not precisely a good material for sword making, beyond decorative purposes.
Perhaps the most infamous example thereof:
