Our company produces sausage casings preserved in either dry salt or a salt brine. This salt water environment causes any metal tools/equipment we have to rust almost over night, including 304 stainless. We've realized we have to buy 316 for our tables but you just cant find knives made of 316. We tried plastic/ceramic knives but they broke too easily, and currently we're using titanium coated ones but they still corrode, albeit slower and they're expensive. Does anyone have any suggestions to combat the pervasive rust, or does anyone know of durable non-metal knives?
