I come from a family of schoolteachers and as far as I can tell since the 19th century the grip they taught was something like the "dynamic tripod", which of course is the one I use (and advocate strongly). Modern teachers who don't teach "proper" postural techniques just don't know better or have been told it doesn't matter. I think it does. There's a proper way to hold a pool cue, a golf club, a violin or a chef's knife. They come from people who were good at it and did it for a living, so what you're looking at are ways of doing it fast, accurately and for extended periods of time without injuring yourself. Handwriting isn't any different, it's just apparently not essential anymore. I concede left-handed proper grips don't have that much tradition. As everything concerning left-handed people, they should get more consideration (maybe looking again at the practical assumptions about symmetry made by right-handed people).
