I decided to make a replica pick-axe. This technique can be used for any of the tools, but i really wanted a pick-axe. There's no zombies outside my house, so I don't need a sword (There's creepers but they keep their distance.) I wanted it to be durable, so I made it out of wooden blocks then painted it. It worked really well!
Also, Just for fun, there's a picture of it below in anaglyphic red/cyan 3D! You know, in case you guys are to lazy to make it...
Step 1: Getting the Template
Step 2: Cut the Blocks
My dad did this part. I wanted to but for some arbitrary reason he doesn't trust a clumsy 17 year old pyromaniac with his circular saw... Go figure. I'll never get parents. Anyway, I cut mine about 1 inch cubed. 2 or 3 would be more realistic but we had limited materials. Make sure they are as perfectly cubed as possible and account for the width of the saw.
