Here is my 2 cents.

A fine straight razor shave is not a result of just one thing - such as a properly honed razors. It is instead an orchestration of several things that come together in as perfect a harmony as possible.

So, first, as you have been directed already, get that razor honed by a professional and if you PM me I will hone it for you for the cost of shipping.
Second - strop strop strop. If you cannot strop yet, you must learn. Nobody I know takes a razor off of the stones and goes straight to a shave. Pressure is much more important than speed here.
Third - Prep that beard. You must have your whiskers softened before your shave. You are aksing for a pretty rough ride without it. Especially your upper lip.
Fourth - Mix good lather. This means have good quality soap or cream mixed to the right consistancy with the right amount of water.
Fifth - Know your whisker growth directions. A North to South pass is not necessarily WTG, and a South to North pass is not necessarily ATG. Get comfortable stretching the skin in the right direction as well.
Sixth - Practice shaving and be willing to have MANY dissapointing shaves to start with. We all had them and occasionaly still do. Light pressure and adjusting blade angles are key here.

When all of the above are correct, you have the highest probablility of a great shave. Notice I did not say you will have a great shave. There are many day to day factors, such as skin condition or how distracted you are that can affect the outcome. I get better shaves when my water softener just regened than I do when it needs to. I can't control that.

In addition, I did not say you need a $500 razor, with a $250 strop and $75 soap with a $275 brush. This just isn't the case. What you need is the skill to on each of those six items and the willingness to practice till you get it.

I hope this helps.
