I think it's a plagiarism, that's why Harbor Freight is getting so big. Just because you're paying more and it's made in America doesn't mean anything, firstly it's just one bit not 2, it's in a shredded plastic bag. But I had a job to do so how bad can it be, well it's bad that you have all these parts to keep up with and a broken bag to hold them. You would think you take the knives off and flip them over with the 2 washers and spacer, they should fit together nicely, no matter where you put the 2 washers with the spacer that isn't there, you will need to adjust the height to make them match. For this money you can buy 2 different bits
