My father gave one of these to me as one of my graduation gifts from college, and I absolutely love it. The tool is clipped to my pocket everyday. I used to keep a single blade, but the lightweight Skeletool has taken its place for good. I primarily use the bottle opener function, but the blade has remained very sharp over the year that Ive had it and I still have both screw bits that it originally came with. I didnt know about the additional bits package so Ill have to look into that. If you want a lightweight tool with the essentials, then pick this tool up.
