This video shows you how to hone (sharpen) a straight razor!
I am assuming your razor is already somewhat sharp, allowing you to start with an 8 000 grit whet stone. If your blade has never been sharpened, you can save some time by getting a lower grit stone in addition to the 8 000. Higher grit stones can also be used - they offer a better edge, but take longer!
What you need:
Straight razor
8000 grit whet stone
Strop paste
Strop
