I see some references and quotes such as:

....will cut arm hairs but not quite shave ready......
How much of a difference is there between the two?? I mean, I'm not going to even try to pretend I'll ever see "Hanging Hair Test Qualified", but was just wondering how far I have to go. My razor will cut my arm hairs easily (with the edge lifted ~ 1/8" - 3/16" off the skin) and will shave, but I know it can be made better.

Thanks in advance for your replies.

Jim.
