[LUA Help] Hiding tools from other users, or just hiding tools in general?

[RFK 2018]

Hi, so I've been trying to get this working for a bit now but I just cannot seem to figure it out.
Is it possible to hide tools with something as simple as

ps. Code thing isn't working for me.. lmfao My bad

hook.Add("SomeHookINeverKnewAbout", "blah", function()

// A bunch of fancy methods or things here
for k, v in pairs (SomeToolsTable) do

if v.ItemName = "remover" then
return true/false
end
end

end
