How can i add and remove tools by touching a block?

i was just wondering if its possible to add and remove tools by touching a part. Its cuz i am making a mini-game game and i want to remove and add tools by touching a part/block.

I am making a mini-game game and i want to add and remove when they spawn (just making an invisible part

To remove tools put this script inside of the part.

function hit(part)
	if hit == nil then return end
	h = game.Players:GetPlayerFromCharacter(part.Parent)
	if h ~= nil then
		c = h.Backpack:GetChildren()
		for i=1,#c do
			c[i]:remove()
		end
	end
end

script.Parent.Touched:connect(hit)
