After starting shaving after 35 years with a beard I ordered a blade samole pack from Connaught shaving a couple of weeks ago.I first tried a Derby which was pretty good 4 shaves before throwing away,then I tried 7 oclock yellow,superb sharpness 6 shaves before ditching,I could possibly have got more.Yesterday I bit the bullet and loaded up a Feather,the first shave was the best yet,no irritation closest shave of all with just two passes.Imagine my disappointment on finding the blade had lost most of its edge after just one shave I had to make four passes on my jawline and under the chin,and still have bristles on the chin and neck i didn't dare doing any more passes as my neck was getting sore.this blade may be the sharpest in the world but in my case only for one shave.Has anyone else found this blade to be so short lived.
