Ooops!  Almost forgot to answer your question:  I believe a blunt edge can be either nose or elbow and both can be extremely sausage.

Mr. Grepper, your mind and tongue are as keen as is the razor’s edge. In your terminology the sentence would read: your mind and tongue are as blunt as is the razor’s edge.
