trying to find the word for...

[Lucas Molina]

please don't think this odd but i collect knives and weapons and was
wondering what the name for the "aztec sword" is in nahuatl.  i've seen
a couple of examples at the New York Natural History Museum, but would
also like to know if anyone knows where i could find a picture on the
net somewhere.  i was thinking about trying to commission a flintknapper
to make one and am baffled about the method used to hold the blade in
place.
