[1.7.10] Changing attack/dig reach

Hi, for some reason the reach is not changing at all. The reach is default for attacking and digging even if I set it.

This is in a TickEvent.PlayerTick event method:

	EntityPlayer player = event.player;

	if(event.phase == Phase.START) {
		if(event.side == Side.SERVER) {
			if(player instanceof EntityPlayerMP) {
				float reach = 5.0F;
				ItemStack heldItem = player.getHeldItem();

				if(heldItem != null) {
					Item item = heldItem.getItem();

					if(item instanceof ICustomReach) {
						reach = ((ICustomReach) item).getReach(heldItem);
					}
				}

				ItemInWorldManager itemInWorldManager = ((EntityPlayerMP) player).theItemInWorldManager;

				if(itemInWorldManager.getBlockReachDistance() != reach) {
					itemInWorldManager.setBlockReachDistance(reach);
				}
			}

Here's my ItemSword class:

package terrarium.item.tool;

import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import terrarium.item.ICustomReach;

public class ItemSword extends ItemTool implements ICustomReach {
public SwordType swordType;

public ItemSword(String name, ToolMaterial material, SwordType swordType) {
	super(name, material);

	this.swordType = swordType;
}

@Override
public boolean isToolType(ToolType type) {
	return type == ToolType.SWORD ? true : false;
}

@Override
public float getReach(ItemStack itemStack) {
	Item item = itemStack.getItem();

	if(item instanceof ItemSword) {
		ItemSword sword = (ItemSword) item;

		System.out.println("HI");

		return 1000.0F;
	}

	return 0F;
}

public static enum SwordType {
	SHORT, LONG;
}
}
