I have the same kinda thing but with Cold Steel folders, hope my little one thinks of the buck 110 and me.Kinda a Remington/Mossberg thing. The 870 was first, but the 500 does things a bit different.
I would go with the 110 purely because it has been the work knife of choice for my dad going on 40 years. He's carried one of some kind or other every day. From the days when a 110 was THE biker knife all the way to today where it's mostly used to cut plastic drain pipe and tape at work.
I can't look at a 110 and not think of my old man.
