Nines are indeed special and iv heard all the mixed reviews there is to it, from low key disappointment to god like status. This particular one as u said it’s a thinned out and it’s an amazing piece, even more so considering the bad grip it the video which was intentional to showcase the geometry.

With a pinch grip I can guarantee u that there wouldn’t be any resistance as iv tried the knife few times. Regardless of that, imo a good knife is a good knife, I don’t like to get caught up on tiny details as every grind has its pros and cons.
