How to make a pixel iron sword!

Take your 7 Light Grey Wool Blocks and make this square, but leave the middle square open and the top right open too.

Then just add a Quartz Block in the middle.

Then take 3 Oak Wood and 4 Dark Oak Wood Planks. With those make this^^.

Then make an arrow shape with 5 Light Grey Wool Blocks and 2 Grey Blocks.

Next add 2 more Light Grey Wool Blocks and 4 more Grey Wool Blocks.

After that add 12 Grey Wool Blocks on the outside.

Then we will start adding the Quartz Blocks in this shape. First you want to make a square then continue it with 3 more on top.

Continue that process till you get up to 10 Block of Quartz.

Last of all cover all the outside in Grey Wool Blocks.

Then you are good to go! Hope you enjoyed! :)
