William Rodgers Knife information?

I have a William Rodgers knife. It has a bone handle and "I cut my way" on one side of the blade and "made in Sheffield England" on the other. The blade is about 6". I think it is a hunting knife and I have a seen a similar knife referred to as a 'Bowie' knife, but don't know what this means!! Does anyone know roughly how much this could be worth or any books where I could find some more information on it? There doesn't seem to be much on the internet! Many thanks for any information you can offer!!
