It's mainly practice and patience. It took me a few weeks to learn but even after that you cannot shave anywhere near as fast as you can with a normal razor without cutting yourself. Also I don't think it warrants that additional time for a slightly closer shave. As for blades yes the feathers are supposed to be the sharpest. They are extremely unforgiving. Again I don't think they are worth buying if someone is thinking of going de. Stick to Israelis they offer a much more forgiving solution which is still very sharp.
Andis maybe, but the cheap end of Wahl products for domestic use are just junk. The commercial clippers are great, and still very affordable.
Wahl make a domestic range ,the usual deals on here , a professional range and animal range. I got a basic pro range refurb and it is very good.
True, I bought the 200 blades when I bought the DE shaver and i don't think i have gone through upto 1/4 of the lot yet because I only use it to tidy up the edges of my beard and shave my head. For those who do a clean face shave, yes they have to in invest in other bits and tbh those bits are optional in regards to the brush and shaving foam sticks...but for me paying a total of upto £25 four years ago for the shaver and blades has been the best cost effective spend i have done in regards to shaving products...if it were gillette products i would have definitely spent more than five times that!
I've rarely had nicks till this week, but that was down to me shaving the mid-front part of my head and then getting the missus to finish it off for me, usually the missus shaves the whole of my head and never have any nicks or cuts. I think it also depends on the blades from what i can remember, because there are some blades that are really sharp.
