Several people will recommend the CRK Mnandi - which unfortunately has a clip, but I think you can take it off.
My recommendation of knives to check that fit your requirements:
- several Moki designs, esp. those with VG10 steel:
Moki's fit & finish is very very good indeed.
- several Mcustas, such as the MC-74D "Take":
- and a personal favourite: nearly all Klotzli knives do exist in a version without a clip. Check
their site for more details. Here is the Walker Sarra:
Or the Wimpff Coral:
Or perhaps go French.
Fontenille-Pataud has several splendid designs, including a shorter "gentlemen laguiole", or an open Le Thiers, ortheir recent "U Cumpa":
Or the elegant "Le Français" by Perceval:
In the Italian style, I do recommend the splendid Lion Steel Opera (picture of one with horn handle):
