I have a set of 6 pearl knives. They are stainless steel w/ pearl handle. The maker is B. Thomas & Co. I tried looking up the company online but could not find any info. They read Cutlers (with a small crown next to it) and below say B. Thomas & Co. Sheffield made by craftsmen. Then say stainless steel made in England. I would like any info you can give me on these and value if any.
