I have a merkur #180 (i think this is also the 23C). I use it to shave my legs and my underarms, but sometimes I have a hard time getting the razor to shave properly. I used to think I just needed to perfect the angle, but now I think it's something else. I think this because if I unscrew the handle just a little, it changes the space that I have between the bottom bar of the razor and the blade itself. Then the razor shaves like a dream. The problem is that this is not very stable, as my leg isn't perfectly flat (it's curved like everyone else's, of course), so it will loosen or tighten at its own whim, whereas if it were tight that wouldn't happen. To be fair, it might still be an angle issue because when I loosen it the angle of the blade changes too, but if that's really the case I still think I need a different razor because I can't put the razor to the skin at that angle (because the handle would get in the way). So what is going on here and/or what am I doing wrong? And if I need to buy a new safety razor (as I believe I do), which one would work for me?
