Morpho Diana Force Dagger Style Folding Knife,Black,Red,Blue

Real heavy duty, built solid no cheap parts here. I bought all four colors, blue, black, silver, red, and everyone of them are built differently, the blue one does not have a spring like the other three, it uses a steel rod and because of that it shoots out fast! Way faster then the spring type. The red one is truly built heavy duty, the other three are of medium weight and built, thinner gauge metal. The red one doesn't have any noticeable defect in aluminum and on the blade like the other colors do. I find this red one to be made far better and of higher quality when compared to the other three colors.
