I don't use it to tie much at all. I use it for photos mostly. It is a great vise though. I had one years ago and sold it. So I got this one several months ago, but I am spoiled on my jvice and my Matthias (which has same sized stem as jvice) which I sometimes put in the jvice tying table.
My Renzetti 3000 is for sale now.
How long have you had your jvice?? I got one of the earliest ones which had the knuckle head. Jay has since updated mine.
