You didn't describe the razor you have now or how you acquired it so it's hard to tell if you're starting out with a razor that "probably" has a sharp edge or is in need of honing or even just being touched up. Whipped Dog can send you a low cost razor that is shave ready and you could have a razor that you can compare your current one to.

As an alternative, there are few universals in life and shaving is one of them. Rather than shipping the razor back and forth, try finding a local barber who could be of help. You may be able to find one that could both touch up your razor and give you pointers on your technique.

Thank you for your service.
