I'd sure like to see a picture of a "Drop Point Shaper". I have no idea what it might look like from the descriptions here???
I formed these with laying out with a template, then stabbing straight down with tiny chisels, relieving the chip then work the surrounding wood down with files and sand paper. My files have a safe edge ground so they only cut on the bottom and one edge. Maybe that is what you are describing? They are visually matched side to side and all traces of tool marks removed. Lastly, the tops are gently rounded over.
I leave no extra wood, just what is left after shaping the lock panels with a tapering V the length of the drop point.
