Welcome, Aimee!  Definitely take a look around, add photos, ask questions (we've got an incredibly knowledgeable group here!), and answer whatever questions you see come up too -- we love discussion here!  Hopefully you can find some answers on those Robesons.  Good to have you here! 

Hi Aimee - welcome to iKC - we're glad you're here!

Robeson made a lot of knives...folders, fixed blade, and kitchen cutlery. If you would post a photo of yours maybe someone here at iKC can help you identify what you have. A clear shot or description of any markings would also help in identifying specifically what you have.
