It appears Cornerstone has changed supplier from Feintechnik to Edgewell Personna. I may get another razor. I am disappointed in their original handle. It could have been so much better. I have just ordered the new Dorco Classic, so I will do a comparison. I am not expecting a Bolin Webb, but something better than mass production. The carts for the new Cornerstone razor are GT5's which are a lot cheaper at Tesco. However, Tesco's Hydro3 cart/Matrix handle Mach3 compatible combo is also an attractive alternative.
