Claim:
A vise, comprising: a fixed jaw having a first gripping surface; a moveable jaw having a second gripping surface; a spindle for providing movement of the moveable jaw relative to the fixed jaw; a semi-nut configured to selectively engage the spindle; and an actuation rod configured to move the semi-nut between an engaged position and a disengaged position with the spindle, wherein the actuation rod has an actuation portion configured to engage and manipulate the semi-nut and an actuation end having a mechanism configured for manual manipulation by a user in order to engage and disengage the semi-nut and wherein the actuation portion has an axial cross section which comprises a circular portion and a flat portion whereby rotating the actuation rod to a first position causes the circular portion to engage a bottom portion of the semi-nut thereby moving the semi-nut to the engaged position and rotating the actuation rod to a second position causes the flat portion to engage the bottom portion of the semi-nut thereby moving the semi-nut to the disengaged position.
