My daily carry
For me personally this knife ranks as one of the most handy blades I have owned and certainly the most handy folder. I carry this daily because it light and isn't too thick for the pocket. In addition to locking open, it also locks closed which is a great feature when you have it in or around thin backpacks and tents.
I have had mine for over 5 years and it is still sharp and the assisted open is still very snappy.
If I lost mine or it was damaged (which is unlikely) I would replace it immediately.
