Medieval Items - Only One Command

Hello! Today, I've made Medieval Items in Minecraft. It adds four new items and one new crafting table!

Click here for the command!

Crafting:
Spear - Arrow + Iron Ingot
Boomarang - Stick + Iron Ingot
Horse Shoe - Leather + Iron Ingot
Leather Workshop - Crafting Table + Leather
All recipes are floor crafting

Tutorial:
With the spear and boomarang, sneak to throw them in the direction your looking.
They will also do damage if you use them as melee weapons. To equip the horse shoe
onto a horse, just throw it onto any horse and its speed will be increased. Use the egg to
place the Leather Workshop, and break it to get the egg back. All the recipes can be seen
by right clicking the top of the table!
