Thread: Slight bluning on finger nail; any point?

Thumbnail test:
TNT: Use a damp thumbnail. A dull edge will pull smoothly and freely over the nail. A sharp edge with well set bevels will dig in and/or drag across the nail with a smooth, even sensation. Practice with a DE blade (e.g. by using electrical tape to tape the DE to your razor's blade). This test is most useful while setting the primary edge/bevels. Try not to use the TNT on any edge over 4k.

For a too sharp or a harsh edge:
Newspaper (approx. 0.1 micron?): 1-3 layers on anything flat. The more heavily inked sections seem to work best. 60 laps. Test every 20 laps thereafter. Approximately 80 to 140 laps is "normal" for most razors. This is just one solution, there are many others.
