I've been carrying a CS Clip Point Tuf-Lite on my keyring now for about a month.
It's been used to cut box tape, twine, loose threads, plastic wrap from CD jewel cases, and open envelopes.
It performs like a (little) champ!!!!!
It came to me pretty sharp out of box. Not as sharp as some other CS products, but pretty sharp non the less.
I can't wait for this one to get dull so that I can put a nice edge on it!!
Also, as indicated before, it's been on my keyring the whole time. I was expecting the handle (and maybe even the blade) to get all scratched up since it would be coming in contact with the keys all day long while in the pocket. The opposite has been true.
No scratches at all noted.
I do suppose, however, that under a microscope they would be evident. But who gives a rat's a** about that.
Free tip: Don't buy directly from CS. That's what I did just to find out (here on the forums) that there are some great on-line vendors that sell for great prices and offer great service as well. I got beat...be smarter than me!!!
Overall: Nice little knife. I would recommend.
