Here is my short clip on my Spyderco Native 5 Fluted Titanium:
At first I was afraid that it would hurt the excellent ergonomics of the knife, but after two days of carry I've found the opposite to be true. It actually adds a little space to the grip, taking it from a 3.5 finger grip (not using the choil) to a full 4 finger frip, which is really great. It also sits really nicely in the pocket, with basically no knife showing. It even fits the look of the knife.
I would also say, Casey was absolutely great with service. There was a slight delay with my clip (due to factors outside his control) and he more than made up for it. I would, and almost certainly will, purchase from him again.
I have bought other low carry titanium clips before, and I'll give you two reasons why I would suggest buying Casey's clips instead:
1 Unlike some other clips, these fit well with no wiggle or forcing necessary (once you get the screws in, my sausage fingers always have trouble with the tiny clip screws).
2 Casey will make sure that you are happy with his products, and responds to all questions in a helpful manner.
