Bob is a Lumbridge smith who runs the shop Bob's Brilliant Axes. He has distributed many fliers advertising his business and offering competitive pricing.
Lumbridge Castle cellar was broken into during The Lost Tribe, he proposed reacting violently to the transgressors. When diplomatic ties were being established between Lumbridge and  Dorgesh-Kaan, a Dorgeshuun goblin, Zanik, was sent to the surface. When she visited Bob's shop, he yelled at her to leave, insulting her, believing her to be like the violent goblins surrounding Lumbridge. However, he later got over his  xenophobic feelings towards the Dorgeshuun, selling a bronze hatchet to Gamdin, a Dorgeshuun tourist.
Bob serves as taskmaster for the
Lumbridge and Draynor Tasks, handing out and replacing the Explorer's ring 2 after completion of the easy task set.
Bob is capable of repairing
degraded equipment at the normal price, including Barrows equipment, ancient equipment, drygore weaponry, noxious weaponry, the ascension crossbow and its off-hand variant, the seismic wand and its off-hand variant, the malevolent, vengeful, and merciless kiteshields, and the frozen key.
Bob is an extremely proficient smith in RuneScape, proven by his ability to repair Barrows, Drygore, and Nex equipment, among others—although it is not known how he acquires spare parts for the armour or weaponry.
It is implied he lives in his shop, because upstairs, there is a room with a bed and dresser. A level 2 woman, possibly his wife, also resides upstairs.
