How to check if player has two of the same tool in Backpack?

I'm making a crafting system and I can't figure out how to see if a player has two of the same tool in their backpack.

Iterating through the backpack and keeping tally should do fine for this.

local backpack = game.Players.LocalPlayer.Backpack

local function getToolCount(toolName)
	local toolCount = 0
	for i, child in pairs(backpack:GetChildren()) do
		if child:IsA("Tool") and child.Name == toolName then
			toolCount = toolCount + 1
		end
	end
	return toolCount
end

-- eg: local swordsInBackack = getToolCount("Sword")
