All About Pocket Knives

Charlie, Thank you for all of your help ...is it possible the hook was also for boot laces as well..the high boots they used to wear ..only reason i ask is i used it in my ad copy as boot lace hook although i probably need to let people know it is a ladies knife ... thank you so much again bsafe joe G

I have a Robeson 1896 to 1899 my number gave me a little problem ..but i am hoping i understand it better now. my number is C73284 and here is an image or 2 of the knife .. i would like to know what model it is since it has a boot hook on it ?
