Hello Scarface99 and welcome to SRP.
A couple of other things you're going to need are a strop, a brush, a bowl and shaving soap.
Most everything is dictated by the budget and how much you are willing to spend.
The B/S/T thread, Straight Razor Designs and a website called Whipped Dog are good places to look.
I suggest that you start very modestly with each until you decide that straight razor shaving is 100% for you.
The 100 shave milestone is a good goal to start with. Shave slow and easy, stay in your comfort zone, watch a ton of video's - The one by our founder Lynn is a must watch and I suggest practicing new strokes with a butter knife.
In no time at all, with a little practice, you'll be shaving like an old pro.
Most of all....Enjoy yourself!
