Hello, Aaron. Welcome to the forums. Do what Papaw said, and soak it for a few days, be patient, although it looks like you have been. Try using a cordless drill on the lowest clutch setting, and work your way up. The vibration will help the penetrant get into the threads.I have also had good luck reversing directions, helps to break the rust. Bill, the ability to fold the handles to the blade allows for compact storage, and protection of the blade, (I'm sure you already know this), not a must have if you are not putting it into a toolbox. I have a couple USA made folding drawknives here, both are a right hand thread . Regards, Lou
