The Nose Knows, or Does It?

Sorry about the lack of a Monday Rambles for this week.  I'll be sure to have one for nest week.  Last week was sooooooo busy that I just did not have time to take notes like I usually do for that post.  This week should be much calmer.

In the meantime,  maybe you can help me with a mystery.  What are these?

They're made out of stone and very heavy.  The question is, why would anyone make noses out of stone?  What are they supposed to represent?

I thought they might  be some kind of tiki thing, but they're marked "Made in Kenya" on the bottom.  I don't recall a tiki tradition in Kenya.  Googling "Kenya stone noses" gets me nowhere.  "Kenya stone carvings" brings up a lot of sites, but I can't find a match and much of it is soapstone, which this most definitely is not.

Thoughts?  Ideas?  Suggestions?
