It should look something like this:
I tried to use google image search, using this image, to find but no luck.

PS: The photo above is photoshop of what I think the cleaver looks like.
I also believe the style of knife you're looking for is called an &quot;ulu&quot; though the OP pix look to be a ulu cleaver.
