How many rivets for a kydex sheath?

[Shotgun]

I want to make a kydex for my Koster Bushcraft and was wondering how many rivets to put into it. I was going to do a rectangular foldover sheath with a rivet on both the bottom corners and then two on the side for a tek lok for a total of 4 rivets. Is that enough?

Should be plenty, as long as the retention is right the rest are just attachment points or for asthetics. Some people like to use alot of rivits, some like few. I noticed the more I worked with kydex the less rivits I was using.

Thanks. I was wondering because I see a lot and a few as well. Wasn't sure if having a lot had some sort of structural purpose.
