I’ve recently bought the cold steel Wild West Bowie knife and I’ve received it covered in this yellow oily, grease inside a plastic bag. I’m never going to use this knife I’m going to display it with a couple other western looking knives I have. I was wondering if anyone knows the best way to clean this oil off the knife and what to use to preserve the knife after as in what’s the best type of oil to keep it preserved. Also if anyone knows how to regularly maintain your knife as in clean if every month or so. Thanks
