OK so only been shaving a few weeks (double edge) that is and so far have only used boots own make which seemed OK Wilkinson sword which i didn't really like much and for the last few shaves been using feathers.Decided to order some more blades to try so I have some Bolzano Superinox ,Gillette 7 0clock super platinums, Personna platinums and Derby extras on the way. Any one got any experience of these and what did they think ?
