Philippines Travel Souvenir: Plastic/Bone Knife Shaped w/Engraved Drawing For Sale

Philippines Travel Souvenir: Plastic or bone Knife Shaped w/Engraved Drawing. The sale called this bone but not certain it is so calling it plastic. Approx 6.75 in long. Not sure etched is the correct term but drawing and lettering have been cut into the plastic so surface is rough and not smooth. Edges a bit rough along blade. Not certain of age. \"YC\" may be initials of artist but only guessing; may be part of the artwork and not initials. Please see photos. Selling as is.
