In my VERY frugal days, I would save the soap slivers and when I had 5>6 of them, I would lay them on a glass plate and warm them in the microwave, slowly. When they got soft and pliant, I would put them in my hands and squeeze them together, to form a bar. Got a little more soap out of them, that way. You might be able to shape a point on a small piece. Good luck.
