Well, the first thing you need to do is decide if the razor is shave ready. I didn't read your previous post so I don't know what was discussed there. If it's the razor it needs to be honed. if it's not then you need to take the blame. There is no magic and no shortcuts here.

I'm sure you have been told this already but you need to give it some time. It's a skill that needs to be learned and getting frustrated will bring you no closer. I would just try doing the sides of your face and no more until you get it right.

Remember, at one time this was the only ticket and everyone else had to learn. So what you are saying is you can't do something every man did say in 1880.

You need to take the attitude you are just going to learn to do it and have the patience to stick with it. if you can't do that then maybe straight shaving just isn't for you.
