Destroy Tool Script?

I'm wondering how I would remove a certain tool when player touches the Brick, so far I have this Script:

function onTouch(hit)
character = hit.Parent
if game:GetService("Players"):GetPlayerFromCharacter(character) then
player = game:GetService("Players"):GetPlayerFromCharacter(character)
tools = player.Backpack
for _,a in pairs(tools) do
if a:IsA("Tool") or a:IsA("HopperBin") then
a:remove()
end
end
end
end

This is what I've tried and it works, I'd just like to know how to remove a certain tool out of the Backpack, for example if I wanted to remove or destroy a tool called 'Pizza' without removing it from other players Backpack, just the player that touched the brick.

This will remove the tools that you choose from the players backpack however will not remove them if the tool is equipped.

tools={}--Put the tool(s) name in here. Remember to put the name in "" and separate them with , .

script.Parent.Touched:connect(function(part)
if part.Parent:FindFirstChild("Humanoid") then
	if game.Players:GetPlayerFromCharacter(part.Parent) then
		player=game.Players:GetPlayerFromCharacter(part.Parent)
		for i,v in pairs (player.Backpack:GetChildren()) do
			if v:IsA("Tool") or v:IsA("HopperBin") then
				for i,c in pairs (tools) do
					if v.Name==c then
						v:Destroy()
					end
				end
			end
		end
	end
end)

This code will remove tools that are in the backpack or equipped:

tools={}--Put the tool(s) name in here. Remember to put the name in "" and separate them with , .

function  remove(tool)
	for i, d in pairs (tools) do
		if tool.Name==d then
			tool:Destroy()
		end
	end
end

script.Parent.Touched:connect(function(part)
	if part.Parent:FindFirstChild("Humanoid") then
		if game.Players:GetPlayerFromCharacter(part.Parent) then
			player=game.Players:GetPlayerFromCharacter(part.Parent)
			for i,v in pairs (player.Backpack:GetChildren()) do
				if v:IsA("Tool") or v:IsA("HopperBin") then
					remove(v)
				end
			end
			for i,v in pairs (part.Parent:GetChildren()) do
				if v:IsA("Tool") or v:IsA("HopperBin") then
					remove(v)
				end
			end
		end	
	end
end)
