LIRS - Large Iron Retention System. Rather than clamping your hook between two parallel surfaces
like a conventional vise, the LIRS utilizes a drawbar to capture the bend of the hook and pull the hook into
the tapered groove of the LIRS nest, where it is securely held. Ideal for larger wire sizes, longer hook shanks
and any application where additional holding power is required, such as spinning or stacking hollow hair
And best of all, its a true in-line rotary vise!
