Grinding a Sword Blade How To?

[Tiberius Clodius Corvinus]

Tiberivs sharp hock: :? Hmm I must admit I dont like sharp swords in reanactment they are dangerous enough as they are,

Absolutely my point. But it's not meant for combat. Its just for authentic feeling. makes a difference IMO. and there's no hurry with the answer. university takes much of my time

btw, is there a limit how long an angle grinder can approximately be used without pausing? I remember for my bench grinder a 10 minute limit, but somehow lost the manual for my angle grinder.
