Well, I've tried all types of approaches to get the grit out of my Imperial Barlow. From spraying with WD-40 to washing under running water to drenching the joint in various lubes and working it back and forth. I'm out of ideas. It still has very noticable grit in the joint area. Does anybody have any other ideas? Oh, and I've tried blowing out the grit (wet and dry) to no avail as well. I'm really quite sad about this, as I'd hate to see a great knife worn out simply because I can't clean it adequately!
