If you're a fan of larger knives, the large is for you, no question. The small is pretty compact, and fully capable, but still pretty small. The large seems, to me, about average for a ton of folders and a great size. I carry a large. I wish I had a small again for work where I'm not convinced a large is permissible in my work. If you /need/ small, go small, but if you already like larger, it's such an easy choice.
