Pin with head for "Flying fan knife"

Made as a simple solution for the “Seemingly a flying knife, it's actually a fan” model, this pin is an adaptation I made that includes a small pin head so it doesn't slide through the blades. I then gently heated the bottom end to melt it into the last fan blade to secure it. Here's the link to the fan blades model:
