A sheath is not the only safe way to carry a Gunting, but it is the only way GUARANTEED to prevent you from accidently opening the knife by snagging the ramp. I've carried a Gunting every day, for the past 4 months or so, and I do not use a sheath, and I have not cut myself. I carry the Gunting by clipping a mini Tek-lok to my belt on my right side, running a loop of speaker wire through the holes on the Tek-lok, then clipping the Gunting to the wire. I carry it this way since I usually wear a coat or jacket which conceals the knife, yet the knife is in the optimal place for a quick draw. Also, it doesn't take up room in my pockets and stays out of the way so the ramp doesn't accidentally snag on anything. Plus, the draw is always the same. If you clip it to your pocket, the draw could be different for each pair of pants depending on where the pockets are located and how thick the fabric is at the spot you clip it. The only disadvantages are that I need to wear a belt, and if I take off my coat the knife is not concealed as well as if it were clipped inside a pocket. Even so, this is an ideal solution for me.
I may end up getting a sheath from Survival Sheath Systems. Not because I need one, but because SSS does great work, I like their clamshell design, and because custom sheaths are cool.
Leo figured it out. The best way to use the clip is to clip the knife to a "dedicated" pocket that you don't use for keys or change. That way you avoid constantly reaching past the ramp and risking an "incident". Honestly though, if you are reasonably alert, you shouldn't have a problem using the clip. Get the knife because it is a great design. Once you have one, you will figure out the best way to carry it.
