To me it looks close enough to a fixed blade to not bother with it. Like its a fixed blade with movable parts that can fail. If
I saw these several months ago and I had the same reaction. I just don't see the benefit of them if you only gain a 1/4" on cutting diameter from the mechanical action. There are quite a few 7/8th's inch fixed blades already out there and the flight problems at high speeds are negligable between the a 7/8th's inch fixed head and a 1 & 1/8th's inch fixed head. Seems to be an answer to a question that nobody asked IMO.
