Disc Design

Well hardox just get's blunted. You will rarely cut through anything anyway as most machines have heavy duty shells so I'd just go with hardox as it's a cheap easy option and if you are getting the whole thing for £30 then you could afford to swap it every couple of events

Well the disc doesn't exactly have a sharp edge, its 10mm thick so its more a hacking action rather than cutting. The company does Hardox 400. But I have tracked down a company that might be able to do it in D2.
