Boker Plus Rocket
I've carried one of these bad boys daily for 4 years or so now. It's a great little knife. The retaining liner strip is fantastically helpful for securing the slip joint while maintaining UK legality. It has really decent edge retention but sharpens easy, and you can tighten the joint with your thumb nail. Plus it has zero intimidation factor. No one recoils when you pull it out of your pocket. Great knife.
