After looking at the pics I am intrigued by the 311, 411, 511,611,711 from the Yard. That might change a bit when when I see better pics, some may be redundant of blades I have already. Like the 611, it looks so similar to the Ganza 6.5 Reg. Then the 611 looks so close to the S6........see what I mean.
I though there was supposed to be a larger blade too?
Thanks for posting the pics.
