Date & Handle Material? Joseph Rodgers table knife

Looking for information on this night. It is a Victorian Regency stamp, and no address is listed. Also unsure what this handle is made of? Thanks in advance for any observations!


Other than the VR surely standing for Victoria Reginae (Queen Victoria), I’m not familiar with the rest of it or that maker. But, I imagine a search online will find you a bit more info. I don’t think it’s silver, unless it’s silver plate that’s been worn off.
