Recently acquired this venerable oldie (1972-1974) which had a rounded point, no edge, and a handle filled with crud.
Cleaned everything with toothpicks, an old toothbrush with diluted detergent, and lastly an ultrasonic cleaner, polished the brass, then reground the blade by hand on wet & dry paper with WD40 as a lubricant.
The new convex edge measures ~25 degrees inclusive and there is a new point too.
