In this case, I'd consider the scissor block application you provided a Tier 2 application. Then again, it's kind of hard to tell because it's never been explained beyond the basic mechanics.
This is a motion I learned in a different set of forms (Palgwes) where we describe it there as two blocks. In either case, maybe the problem isn't that a Tier 1 application doesn't exist, but the problem is that the Tier 1 application is woefully inefficient compared to other simpler options.
See, I'd consider that trap/break motion as the simplest application and therefore tier 1.
That was from memory though - I can check the actual pattern description where that block features at some point and see what it actually says?
It's possible that it states two blocks, but I can't remember off the top of my head...
Are these sort of basic simple applications not described when you're initially taught the form?
