Another post on the knee vices got me to thinking which is scary some times. I have liked the look of the finger vices shown in some of AK Best first addition books I have, but even though I have watched for one I have never come across one. from the photos they look a little like a pair of hackle pliers with a knob screw on the side to lock the hook in place. Seems like a simple device that would be fun to tie on once in a while, while on the road around the house while watching tv or at work. Has any one used one of these before who can comment on how well they work? Also does any one know if you can still buy one or how much they cost?
