Equipping the tool for the first time usually doesn't cause any problems, but any subsequent equips does.

local play = game.Players.LocalPlayer
char = play.Character
hum = char:WaitForChild("Humanoid")
rhand = char:WaitForChild("RightHand")
tool = script.Parent
sword = tool.LawSword

tool.Equipped:connect(function()
    workspace.LawSwordSheathed.Transparency = 1
    workspace.Sheath.Transparency = 0
    sword.CFrame = rhand.CFrame * CFrame.new(0,1.75,-4)
    sword.CFrame = sword.CFrame * CFrame.Angles(3.7,0,1.45)
    local weld = Instance.new("Weld")
    weld.Parent = sword
    weld.Part0 = sword
    weld.C0 = sword.CFrame:inverse()
    weld.Part1 = rhand
    weld.C1 = rhand.CFrame:inverse()
    sword.Anchored = false
end)

tool.Unequipped:connect(function()
    workspace.LawSwordSheathed.Transparency = 0
    workspace.Sheath.Transparency = 1
end)
