Are there any school/style of Japanese swordsmanship that teach blocking (a parry or deflect is fine as long as there is contact between them) incoming attacks with the sharp edge of the blade of a katana?
Edit: I keep hearing that blocking/parrying with the edge of the katana was not done because it would dull the blade. Yet, I know of at least one kata in Aikido that does just that: You must block with the edge. I was described this as a "Yes, it's not done that's why we are doing it that way...". So, I want to know is this accurate or an urban myth?
