Beginner in straight razor shaving help!!!

[Ilie]

Hi, first of all my name is Ilié and i leave in France. I'm 18 years old and i am shaving with a sh*tty BIC razor....
First of all: does a straight razor give a closer shave than the mach3/BIC razors?
I want to get started in straight razor shaving and i would need some advice about what brand and type should i buy, and also the honing tools...
I have found a DOVO razor at home , with some rust stains on it, and i would like to ask you what do you think about it first. Is it worth the effort of bringing it back to life? or i should buy another dovo?
So please give me advices please!!

I'll post a photo of the razor. i think the blade is pretty decent, i tried to hone it but i think i did more bad than good things haha....
can you tell me if it's worth something? good quality or crap?

THANK YOU!!
