The knife itself is .. Well, expedient. It keeps the blade's perfect and it wobbles absolutely nothing at all. I will therefore guaranteed even in the coming months - if not years - happy.
However, the plastic handle feels not particularly valuable. The two plastic discs can be effortlessly easy in the middle of another press and the printing on the outside was not right either printed or they can be washed out. This is but a hindrance when it comes to shaving in any way; it's just a small optical defect and expected almost for the price.
The metal handle is there but quite a different story. It lies securely in your hand and has for shaving a very pleasant form. As you can already half an hour before the mirror are without a will your fingers tired.
Rust is so far no trace also. After each shave the knife is extracted with me, so that no water remains inside and remain until now, the razor has held up well with me.
OK, we get to the blades. For the price you can buy them already safely be quite. They are very comfortable and keep their sharpness also pretty good. I change on principle the blades after every third or fourth shaving, but they would also hold guarantees much longer. At 300 blades are also not on a budget.
I've already got a few people to do that you - contrary any Rasierlogik and rules - with a razor blade and good after every shave even a can shave against the grain times to remove the beard hairs more precisely. Unfortunately, this is the Derby blades when not possible for me to start as these "stutter" against the grain to and I do not want to risk therefore skin irritation and / or cuts. However, I would also expect such benefits only from the more expensive Feather blades that also should come to the house to me for comparison purposes still soon.
In a normal shave I am, however, completely satisfied with Derby!
So anyone who is not sure if he should dare even to go to the knife, which can access here quietly. For the price you get a very good insight into the blade shaving and you will be seen by very decent quality products surprised.
