This Remix adds a finger saver to the handle, a thumb rest to the blade holder, and a blade support to the non magnet version of the Karambit. This should reduce the chance for a person like myself from slipping and cutting myself. I also felt a blade support would increase the blade rigidity.
I love this design by BiscuitsOnTheFloor as it makes a great utility knife.
