We really like this new wood-handled hand vise with its rotary cam. Simply turn the wood handle and the spring-loaded vice jaws open and close smoothly and precisely. Handle is hollow to enable you to hold long pieces of wire up to 4 mm in diameter. The serrated jaws are 1/2" wide with a maximum opening of 3/8" (9.3 mm). Overall length is 5 5/8".

Note: "vice" is a commonly used spelling outside of the US.
