Stethoscope

A Stethoscope can be bought from Martin Thwait at the Rogue's Den. The player does not have to play the Rogue's Den minigame to purchase items from Martin Thwait, so the minigame's level 50 Thieving and level 50 Agility requirements do not apply to stethoscope purchases.

A stethoscope increases the chance of successfully cracking the Wall safes in the centre of the Rogue's Den main chamber, near Martin Thwait. A stethoscope, however, has no effect when cracking the safes in the minigame itself or for any other thieving activity, like opening locked chests.

A stethoscope has no known medicinal or health use in RuneScape, unlike on Earth.
