I was chatting with someone on an unrelated topic on another forum when he stated (and he is very knowledgeable on historic archery techniques) that grooving was only carried out in one region and that, historically, most (asiatic) hornbows were not grooved. Any one know how true this might be, I know everyone everywhere grooves horn and core now-a-days, but, it would be a huge time-saver if some types of bow did not need to be grooved
