I do not understand, try the tip is subjected without the lid?
Yes, playing the top without the lid, like the old Hollow Point from Spintastics.
Eventually I will make a custom tip and on the inside I will put a smooth conical surface (maybe with a bearing
) for tricks like Pencil Sharpener.
Also, when you hit the open body, even with just the knot at the end of the string, it rings, what is a nice effect.
