The 18mm snap off knife is the bigger brother to the 9mm knife. It has a plastic case with a retractable snap-off 18mm steel blade. The back end of the knife pulls off easily and a new blade can be inserted quickly and simply. When the end of the blade goes blunt simply pull off the back end of the knife insert the blade in the slit on the end and snap off the blunt part of the blade. Clip the back of the knife back on and you are ready to go again.
