4 stars because I like the cleaver idea... the issue is it folds over almost twice on me (size 5) so it defeats the purpose in being a low profile belt and it's no longer that clear when doubled over.

The clasp itself is the best part - it's low profile and sits even flatter if you put it to the side of the button on your pants, rather than right on top of it like you would a normal buckle.

Smaller sizes / Designs / fabric options would be an improvement.

I found I prefer regular belts with the 2 metal loops on one end...  They look nice in case your shirt rides up a bit, fit better, and most are still low profile.
