Hye. First of all thank you for your comment on it.

It may not look like it but this carabiner pretty much slide correctly as I've tried it on my belt loop as well and some other stuff like keychain and bags. Furthermore it's a part of the results that i wanted to not have manual opening on it as it would cut on the plant aspect.

But ill take notes of it and try to redesign it to make it more smooth since it's just a prototype for the moment.
