Let me make the case for a hole.
I carry these folders inside the pants, sandwiched against my baby soft buttocks and the belt. Folding knives are a risk of opening up, if a thumb stud catches on a shirt tail, or a seam. And that includes flippers, had that happen once, and cut my thumb.
This opened up once,
it has a rather predominant pants side stud, which catches on things. After having the blade open up after a bathroom break, and create a hole in the pants seat,
I decided to grind that stud down as much as possible., and round it. No accidental opening yet, but perhaps, I am a bit more observant. Could have received a nasty slice on something fleshy, and that made an impression, so to speak. .
I have a rather old Benchmade with the hole, never had it catch on anything. However, your carry mode, and needs are likely different.
