Having dealt in cutlery in a small, person to person way for some years, I have gathered a small collection which I go to every so often, according to my needs, be they work or dress occasions. Some I se aside new, some are trade-ins from years back. See photo below..
I recently tried the pocket clip type and really liked it, but then found that the hem of my jacket would sometimes catch the clip and pull th eknife from my pocket..OK if I find the knife right away..but not good if I lose it.
I too, prefer carbon blades..Opinel for instance, has outstanding carbon steel..of course, they have stainless too. One Chinese line which I have found to be decent is the "Rough rider" series which are carried by Frost and I think, SMKW.
I may go to sheath carry for the larger Stockman knives, such as the Buck Creek yellow handle at the top of the photo, or the AG Russell "Woods Walker", the only straight knife in the photo.
I may even get one of those Svord, peasant knives..forged in New Zealand, and of high carbon and of tough but simple design.
