Franco,the use of Einstein's hackneyed quote would be amusing if relevant but you have missed the point entirely.
Cheap swords are a valuable study resource even if in poor condition,sugata,nakago,yasurimei,hamon,hada are all aspects that can be studied in detail in conjunction with good reference books;there is absolutely no substitute for 'hands on' study.
Brian,you seem a bit confused.You quoted my post to warn others against mediocrity but then go on to describe your own collection which frankly,sounds mediocre.
Japanese swords may be high end art in your opinion which is a very elitist view,I try to keep a more open mind and accept that all art forms have merit at many levels and try to maintain a Western perspective as far as study and research are concerned and not allow myself to become bound up in the quasi-Japanese way that many sword-pseuds have adopted.
ps;are you the Brian from 'Family Guy'?
