Hi! I want to buy a new practise foil blade as mine was broken. I usually buy the uhlmann standard non-electric foil blade with dummy point.But I heard of some unwired blade(bare blade),what it is?Is it the same of non-electric blade?Can I buy one bare blade and put on the dummy point by myself so it makes practise blade,is it the way like this? Or,which non-electric blade is the best now? Thanks!
