Yes Oliver, the 'standard' will cut and snap fine hackles and will slip also.
I'm still on the standard ones I got with my 'begginers' kit (begginers **** more like) 20 yrs ago. I knew even back then that something wasn't quite right,so I tried a modification which works fine for me and has remained unchanged ever since... and it costs nowt!
Take some shrink tubing or some of that plastic tubing you get with braided loops etc. Cut 2 small pieces about 4 or 5 mm (to suit the size of the nose on yer pliers) ...I'm sure you can figure the rest out
