Just stumbled across this and have never seen this vise before, but dang does it look nice! Has an interesting 'C' shaped arm coming out to the hook jaws that would be really nice for long material ties. One of the accessories is a Dual Material Clip that slides into one of the accessory holes and can be placed where you want. Going to have to look around some more and see if i can find any better pics of the business end that holds the hook and how the jaws adjust and lock down. Heck, i just like the look of it.
