Kunai Knife

[Lobberuno]

Hi!, can u help me?

I like too much this custom weapon, because there is no many ninja weapons officially released by Lego Group, the kunai is a weapon very used in Naruto stories and also I have many old spears that I don't use anymore... so these are my work until today... I think I can paint these for a dark grey finish colour.

I saw in your photos, the kunais have a circle finish on the bottom... How did you do this? Applying heat or something welding techniques?
