i was wondering how I would make it so a tool would have an enchant on crafting?

Override Item#onCreated(ItemStack stack, World world, EntityPlayer player) in your item class and add whatever enchantment you want to the stack.

 

Or, if it's not a custom class, use FML's ItemCraftedEvent.

Something like this:

 

public void onCreated(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) {
    	par1ItemStack.addEnchantment(Enchantment.sharpness, 2);
       //                                                     NAME                    LVL
    }

The problem with onCreated is that its run twice. Both on server and client.

 

I have some code where I random choose an enchantment and I can see that it runs it twice.

 

It gives me a problem because I want to take levels from the player when the item is crafted.

You check to see if its server world before you add the enchantment...

 

Also, you can add the enchanted item as the output of the recipe.
