Being able to pin miniatures is a skill that benefits anyone putting together multi part gaming miniatures. Metal figures especially acheive much greater tolerance to strain. It allows you to strengthen glue bonds that have a low shear strength and in this case allowed me to fix a ruined necron figure. The blade and part of the haft had snapped off above his hand.
I'm using a pin vice here with a 1 mm drill bit. The first piece I attempted was down into the hand. Unfortunately the scoring on the shaft allowed the drill to snap the handle again but luckily the little part came out just like a little bead. Here you can see it on the paperclip which will become the pin.
