I have decided to go ahead and start producing replicas of Lara's ice axe from the new Tomb Raider 2013 game. Mold was made from two different brands of silicone; Pinkysil and I don't even know what the blue part is. I think it's generic from Barnes.com.au. I first tried casting them out of epoxy resin but failed miserably due to the incredibly long set times and amount of heat required. I switched to a polyurethane resin (4PU from barnes) with a work time of 5 minutes and set time of 30 minutes and it has been working great. Less bubbles as well, due to the thin oily consistency (unlike the epoxy, which had the consistency of tar or syrup).
Here are some pictures of the official render and progress of the build. The finished product will be weathered just like the render. So far I'm up to the detailing and weathering on the first axe, after the black handle paint sets better, of course. This is my first time making a mold, casting resin, and producing a replica so please don't tear me apart. :
