Scottish Photographic Federation
Founded in 1903, the Scottish Photographic Federation (SPF) is a non-profit-making body which includes in its objects the discovery, promotion and protection of amateur photography throughout Scotland, and is the only body recognized by international agencies as representing the interests of Scottish Camera Clubs on a national basis. Most Scottish Camera Clubs are affiliated to the SPF and thus participate together, and against each other, in inter-Club, National and International Competitions.
This product works as advertised and cuts very nice circles after you get the hang of it, which doesn't take long. For safety when not in use, be sure to stow the blade so that it is not projecting down as it is when being used.
