From what I read this knife was made in several sizes from 2 to 6.5 inches !! It was made in bronze so that is probably what yours is !! They were made pre 1970 as souveniers for those that visited the statue and possibly later than that !! There are several types of knives that are on the web as well as a bunch of other souvenier items !! I think value would be minimal since many were made !!
