Look at what the manufacturer says:

Stonefisher design, test, develop and manufacture their own professional fishing equipment.  We feel that by using only the highest grade materials in manufacturing our own brand, we can keep tight control of the overall quality and ultimate cost of a product for the keen fisherman.  Our aim is to build a reputation that becomes synonymous with quality, provided at an affordable price. 

We at Stonefisher are dedicated to helping disabled people and their carers.  Our target at Stonefisher is to become Europe's number one supplier of first class quality terminal fishing tackle and accessories.  In turn this will lead to employing disabled people no matter what their disability.  A percentage of our profit goes to a charity helping disabled children with their disablilities.
