I'm trying to find out more information on this cool little knife made in Sheffield, England for Fredrick Lunning Inc. It is 4.5" long with a 2.25 inch "Stainless De-Luxe" blade and a 2.25" Mother of Pearl handle. There is not much info online that I could find. I don't know if this was a promotional item for Lunning but I don't think it's a "salesman sample". I am not looking for valuation but just want to know more about this knife. Any help would be appreciated. Thanks.
