Does anyone know what kind of insect it is that eats horn scales? Are they worms, maggots, or what? All of my horn-scaled razors have insect damage. The insects are long gone without trace except for the holes and gnash marks. Do they only eat fresh horn or do they eat old seasoned scales also? Blade oil and soap do not seem to deter them. We can't seem to have anything natural, just stuff made out of oil! I know termites eat wood. There goes the plans for wooden scales!...
