That helps. Here are some suggestions. All are under $100, have clips, ride relatively low. I didn't check the 50/50 combo edge criterion, since many of these available in a variety of edges.
"Jeans" Office Casual Knives
- Camillus EDC
- Benchmade 705 (I don't remember how low this rides, but I think it would be OK)
- CRKT Point Guard
- Some Spydercos probably fit in here, but I'll let others with more knowledge make the suggestions
Dressier Knives
- Camillus EDC 125th Anniversary Edition
- CRKT Tighe Tac
- Gerber AR 3.0 (best buy, if you can live with the steel)
- Kershaw Chive (esp. the boron carbide coated one!)
- Kershaw Rainbow leek (sticks out a bit more than others)
And of course, the venerable Swiss Army Knife -- appropriate for almost any occasion, but of course no clip. Hope that helps.
