I designed here spear that contains a gem within the head of the spear to hold its power. This was designed not to be sharp so the their should no sharp ends besides the point.
You can shrink the size to about 30% and this works well as a spinning stick/pen.
Size of Spear Combined: Height: 32.9 inches Handle thickeness: 1.12 inches diameter
Nice to have as a decoration piece or as a prop for cosplay.
