Let's face it guys. We are all in the craft of tying flies because we want to produce a product that we will use or maybe just admire. Once you are satisfied with the information you get about the quality of a vise you are considering you start to evaluate the extra features. It's just like buying a car. The ultimate scenario is when you buy the really deluxe model just for the sake of owning it even if you rarely use it.
I'm not wealthy enough to do this with vises but I do have some premium materials that I have no intenion of using. I just take them out on occassion to pet and admire.
