How do I stop an animation without stopping other animations?

Hi. I'm making a punch tool. The following code stops all animations, resulting in the player having no animations until a key is pressed. How can I stop only one animation without the others being stopped?

tool.Unequipped:connect(function()
    local hum = char:WaitForChild("Humanoid")
        for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
            anim:Stop()
        end
end)

Here's the full localscript:

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local tool = script.Parent
local swingsound = tool:WaitForChild("Swing")
local canattack = tool:WaitForChild("CanAttack")
local debounce = false
local UIS = game:GetService('UserInputService')

tool.Equipped:connect(function()
    local idle = script.Parent.Parent.Humanoid:LoadAnimation(script.Idle)
    idle:Play()
    idle.Looped = true
end)

tool.Activated:connect(function()
    if debounce == false then -- check if debounce is false
        local choose = math.random(1,2)
        canattack.Value = true
        if choose == 1 then
            debounce = true -- set debounce as true
            local swing1animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch1)
            swingsound:Play()
            swing1animation:Play()
            wait(.5) -- wait 
            debounce = false -- set debounce as false so the code can run again
        elseif choose == 2 then
            debounce = true -- set debounce as true
            local swing2animation = script.Parent.Parent.Humanoid:LoadAnimation(script.Punch2)
            swingsound:Play()
            swing2animation:Play()
            wait(.5) -- wait 
            debounce = false -- set debounce as false so the code can run again
        end
    end
end)

tool.Deactivated:connect(function()
    canattack.Value = true
end)

tool.Unequipped:connect(function()
    local hum = char:WaitForChild("Humanoid")
        for _,anim in pairs(hum:GetPlayingAnimationTracks()) do
            anim:Stop()
        end
end)
