All About Pocket Knives

Got these is a box after some bartering not sure what I have, How old, who made them , did they ever have scales? Unable to see any tang mark, their are pretty pitted, not sure even what era they are to be in. Just an uneducated guess the tang it self appears to be mid 1800's to maybe early 1900's purely a guess.

Maybe a Vintage throw away knife????????????
Like a box cutter.................???
Or low profile model made with only brass liners???????????

Simple but functional.
I like um"............
