This is the most popular of the lower priced vices. A solid dependable vice with clamp base. Lever action opens the spring loaded jaws which will hold a range of hook sizes down to about size #16 though if you tie a lot of smaller flies a vice with a finer jaw would be better. The head rotates fully through 360 degrees. Has a decent size clamp for fiting on tables or benches and the height can be adjusted.
