Thank you much friends. Makes sense! Though as I am a beginner, I decided to trust the guy from the shop...:/

I am from Brazil, live in São Paulo. There are not so many straight razor lovers here..the specializer shop was in France (I was travelling around)

Now, I suppose what you mean by "honing" includes the whole sharpening process: from early gritstone to leatherstrop...
I have a 1000 gritstone, a 6000 stone, and a leatherstrop with paste...

The idea would be taking to a pro so I do not damage any further, though I wanted to learn how to do these things myself.
Do you think I can do it myself with these gear I have??
