RE: Chinese DE Blade PIF
Used a Mingshi Blue Diamond Super White Blade this morning - what a surprise! My estimation is that it is 98% a Feather! Just as sharp but a little more forgiving. I put it in my newly acquired BRW Bull Mastiff (many thanks, Dunc) which has a Gillette New head - which was both unfamiliar to me and the head a little inclined to bite, as you know. Got a DFS using Richard's Opus 80 creme (gorgeous stuff, many thanks) and my newly adopted face lathering, with three tiny blood spots on my neck where a Feather always gives me weepers - or I use a Feather to give myself weepers, anyway.
So testers - watch out for Mingshi Blue Diamond Super White Blades - they are good!
