David, there is a lot of discussion about what is sharp enough. Get them as sharp as you can, but remember, you are gonna send that thing thru flesh at 150(+) fps. I am pretty sure paper will slice you open if you used it well.
Of more concern to me with your description is the need for a harder steel to hold a 25 degree single taper edge. If the steel is too soft, it will fold and fail. Sometimes a double bevel edge is just better (stronger) for the metal being used.
Experiment and see oh. . and. . post pix !
