He's absolutely correct about the burr. I use multiple stones down to 4000 grit, strop with ruby, leather, and finish on linen paper or my arm if feeling steady enough. Keeping the angle true is important but I never drag the edge back across the stones. It takes a lot of practice but I use one hand and flip the blade at the end of the pass and return the other side in the reverse direction. Works well for me as I never have to resharpen for one deer using the same blade to debone, and process. I do use a separate knife to gut and skin. Broadheads same.
