He first made a mold for the axe handle, then filled it full of gummy bears and resin. Then he attached the axe head. Pretty simple. Actually, it’s not. Especially the part where “gummy residue” gets stuck to the outside of the axe handle, and you have to hand-apply resin to cover it up.
It certainly makes a pretty axe handle. Not that a man needs a pretty axe handle. If you want to try and make one yourself you can check out a step-by-step pictorial of the build here. Good luck if you are chopping wood in the forest and a bear wants to eat your large stick of gummies, Pete.
