If it were my knife, I would want it to have a more reduced guard than the Randall quillons above. Just enough, I suppose, to prevent the hand sliding up. Like the Randall, though, I would want to have a flattened grip so as to index the blade for slashes and cuts.
Then, again, I have mostly given up my dagger collection because of a lack of usefulness (to me). Still, I look forward to seeing how these two turn out!
