thanks play i will look them up
as an aside,for those who have to shave every day, have a guess how many strokes of the blade you make by the time the job is done.
its a bit of a party trick of mine asking friends how mnay strokes they make.
usual reply is 20-30-maybe even 40
give it a try,if your like the rest of us, you'll stop counting after...
200+
