Hello,
Im new to both straight razors and forums. I tried to search for info on how to find the right blade size, but can't find what I'm looking for.

I have a nice shaving whipped dog straight razor from larry. I'm curious as to the pro's and con's of having a larger blade size (7/8) or having a smaller blade size (3/8) or something in between. I know everyone has to figure things out for their own preferences, but I would rather not make a pricey mistake buying a razor that is uncomfortable to handle when I decide to buy my first "new" razor (whipped dog is a freshly honed used razor).

Aside from a smaller size being easier to handle the mustache area, what are your thoughts?

If a post already exists covering this, please let me know.
