Sinker mold?

The only thing I can think of is use multiple smaller split shots or maybe use a pegged egg sinker?

What if you replaced the the blade with a small wire...Let the mold pour a solid round ball with a hole in the center and to use it, just thread your line through it and then back through it again. The line would hold the sinker in place and there would be no pinch on the line, plus you could move it up and down the line if you needed too. But like I said..that's my idea and my 2 cents.....GF
