1960's-era Robinson Knive Company Stainless Steak Knives

Hello,

I recently purchased six 1960's- era Robinson Knife Company Stainless Steak Knives (set) in new, unused condition (paper wrappers, no box) for my wife's kitchen, but when I received them, they seemed so unusual that I thought I'd ask for an appraisal first before I did anything with them. They have brown metallic (sparkle) handles. There is an etching, "Robinson Stainless USA" on the blade near handle.

Could anyone tell me if they have any collectible value?



Thanks,

Mike
