I have a few modern knives, less than 8 that are left over from when I used to carry them. I have probably close to 100 traditional folder if you count Swiss Army knives. I no longer carry or use modern folders at all, the few I have are either too cheap to bother selling off or a couple of my favorites that remain for the memories.
I used to carry two knives at a time, either two modern one handed that changed weekly, or one modern and a Swiss Army knife for the tools, though the SAK saw most of the use.
Now I am down to carrying one knife at a time, I try to carry knives that will age and show character with use, it helps keep the SAKs out of my pocket so I can enjoy my classics.
I hope to have a small collection of knives that I carried on a regular basic to pass on to my son that he can remember me by as I have with my father and grandfather.
I have found that I enjoy the character of the traditional knives and the way carbon steel sharpens and patinas. They also it much better and are easier to use in public.
