I have several opinions on pocket clips.
I like tip up. I carry my knife to the rear of my front pocket and the side of the pocket seems to me would keep the blade from opening. I also think the clip should be reversable with little screw in plugs to fill the holes that are not in use.
I also like deep pocket cary. I didn't think I would like the clip on my EDI but, I do.
The clip is, for the most part, the only piece of the knife that is ever seen so, it should look good, have some class, not look like an afterthought.
Darrel, the clip on the implus is outstanding! It clips securely and looks good too. If it were only tip up...
That's all I've got to say about that.
