1 knife. I only need one weapon to fuck a bishop and I'd be worried about the other guy getting the second hammer while I wasn't focusing on it. Plus I tend to instinctively go for a punch-in-the-throat and a knife in my hand would only add to that (although that added bit would probably be a manslaughter charge)Low iq and drugs. Based on my calculations 100 would be low
2 Hammers or 1 casual knife for self defence?
