We discussed this on the old forum (hey, the search function works for me there.....); I'm not sure what the outcome was, but I THINK it was that the convex ones are tools, and all Igorot tribes had different versions (length to height ratio for blade, "nose" length.....). Maybe I'll try to check. How do I find the old forum? I forget.......Mike, the finger is great; you gotta grab the finger; you'll love it
