Touch and Touchended events when player is on the edge?

I'm trying to make a sword arena script where if you are in a certain area then you get a sword and if you leave that area the sword is removed

Possible ways I could have done this: 1. Check if a player is in a certain X, Y, Z 2. Check if a player is in a region using region3 3. Check if a player has touched a brick

I used option 3 and have the below code

opened = false
local check = game.Workspace.check
local sword = game.ReplicatedStorage.Heal

check.Touched:connect(function(hit)
    if opened then
        local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
        if hit.Parent:FindFirstChild("Humanoid") then
            char = plr.Character
            if not hit.Parent:FindFirstChild("Heal") then
                if not game.Players[hit.Parent.Name].Backpack:FindFirstChild(sword.Name) then
                    sword:Clone().Parent = hit.Parent
                    wait(5)
                end
            end
        end
    end 
end)

function CheckIfPlayerIsInArea(check,Character)
    local touching = check:GetTouchingParts()
    for i=1,#touching do
        if touching[i] == Character.HumanoidRootPart then
            return true
        end
    end
    return false
end

check.TouchEnded:connect(function(remove)
    if remove.Parent:FindFirstChild("Humanoid") then
        local plr = game.Players:GetPlayerFromCharacter(remove.Parent)
        local char =  plr.Character
        if CheckIfPlayerIsInArea(check, char) == false then
            if plr.Backpack:FindFirstChild("Heal") then
                plr.Backpack.Heal:Destroy()
            elseif plr.Character:FindFirstChild("Heal") then
                char.Heal:Destroy()
            end
        end
    end
 end)

The problem is if the user is on the edge it spam gives them the sword making the annoying unsheath sound for swords.

I've tried adding a wait() to both remove and give functions but it didn't seem to do much.

How do I get around this as I don't want players spamming their sword and is there a better way to script this?

Thanks in advance!
