Hi All,
I did an online search using “philippine butcher knife” and, to my complete surprise, got a positive ID. My knife is a plamenko variant called a kutsilyo de busong (bellied knife). A Filipino guy posted a picture and comments on reddit (
https://www.reddit.com/r/chefknives/..._a_tradtional/). He says that the knife is no longer commonly used domestically but can still be seen in wet markets where it is used for cutting up meat. There is also a U-tube video called “The Original Bolo de Ilonggo (
https://www.youtube.com/watch?v=W7i19CDrPmU) where another Filipino guy shows and describes a number of knives and bolos. The kutsilyo de busong is the fourth piece described and the narrator uses that name for the knife.
Sincerely,
RobT
