I've trained HEMA for a while (mostly Lichtenauer, some Fiore) and am comfortable with synthetic and steel feders. I'm looking to buy my own steel (blunted of course) and I've found that sites like Kult Of Athena have a category of "stage combat" swords, which it says have slightly thicker-than-average blades (so as to be more durable when taking a beating). I've also noticed that these stage combat swords are often priced a bit lower than feders or other tournament steel.
I'm considering buying a one of these stage combat blades (this one, if you're curious) to train HEMA. It's a few inches shorter and a few ounces heavier than the feders I've used, but otherwise seems decent (EN45 is acceptable steel, right?) I would mostly use it for solo drills and possibly some light partner drills, but I would NOT be doing full bouting or tournaments with it.
People who have done HEMA longer than me, is this a decent sword, or should I really stick to feders?
