A new Pin Vise for removably retaining various sizes of pins for grinding to a specified length which allows the user to easily load and unload the pin for increased productivity. The inventive device includes a base member, a support shaft secured to the base member orthogonally, a top member secured to the support shaft opposite of the base member, and a spring loaded pin retaining means slidably secured to the top member which retains the pin against the top member thereby allowing grinding to the specified length.
