This clip is called the model 24 from knifekits. Yes, I put it on using 2 strategically placed holes, nothing else, no backplate. Some Locktite.
Will it break? Not easily. It actually takes a good amount of flex from the act of using clip. It holds great. I had tried it before on a beater Trekker.. And that one went through a beating. The scale can simply be replaced if anything does happen but these scales are surprisingly very resident.
This one's scale was replaced along with a Centurion using the GITD scales. Both bi-color. This one is a Sentinel Plus.
