The Luna Boost from Real Steel is like the original Luna, but instead of the non-locking slip joint, it has a titanium frame lock. Along with the frame lock, the D2 steel has been upgraded to Bohler N690 which is easier to sharpen. With a blade made of Bohler N690 and a carbon fiber handle, you have a knife made from great materials. The sleek, lightweight, and slender design makes it perfect for everyday carry in a suit, jeans, slacks, shirt, and just about anywhere. If you are looking for a classy knife, this is the knife for you!
