If you can't decide what your favorite color is, don't be sad, this knife solves that problem for you. This rainbow hued knife has a little bit of each color so you'll never have to choose just one shade. The stainless steel blade is four inches long and is just as effective as a black blade. The handle joins the fun with it being black with a rainbow colored liner, so you are constantly surrounded by colors. The colors shine even when the blade is closed and kept in place with the included pocket clip.
