Yes. I tried them last year or the year before, can't recall. I took a nice buck with the 2 blade but one of the blades bent and the arrow did not pass through. The buck only went 40 yards and there was a lot of blood but overall, I did not like the performance so I went back to fixed blades.
I like to resharpen my blades and I found it was very hard to do with those thin blades.
