I use a green Bic and never ever lose my lighters. They get used until they die and get thrown in the trash. If someone was to take my lighter, they would get their ass kicked and never come in my house again. Trust is important at my house and if I can't trust you not to take my lighter than I can't trust you at all and will have nothing to do with you.
Taking my lighter is flurting with disaster and can get you hurt.
