The Doctor has used other sonic devices similar to the sonic screwdriver, including the "door handle" of Inferno (Liz Shaw having one of her own) and a pen-sized white noise generator in Four to Doomsday.
In the 1965 episode "Trap of Steel", the Doctor uses an apparently ordinary screwdriver to examine the metal of the Drahvin spaceship and other tasks.
In the 1979 serial "City of Death", Count Scarlioni's henchmen use a "sonic knife" to cut the glass in front of the Mona Lisa.
In the 1985 serial "Attack of the Cybermen", the Sixth Doctor uses a "sonic lance".
In the 2005 episodes "The Empty Child" and "The Doctor Dances", Jack Harkness uses a "sonic blaster", referred to by Rose Tyler as a "squareness gun", capable of "digitising" structures by disintegrating them and then reversing the process, among other functions. The device resurfaces in "Silence in the Library" and "Forest of the Dead", now wielded by River Song. Steven Moffat confirmed in an episode of Doctor Who Confidential that the device was the same one.
In "Smith and Jones", Martha Jones sarcastically asks if he's got a "laser spanner" as well as a sonic screwdriver, which he apparently did until it was stolen by Emmeline Pankhurst, described by the Doctor as a "cheeky woman".
In "The Sound of Drums", the Master reveals his laser screwdriver. Unlike the sonic screwdriver, it is used as a weapon that can kill as well as artificially age its target, using technology developed by Lazarus Laboratories originally seen in "The Lazarus Experiment". It includes isomorphic controls, allowing only the Master to use the device. The design of the prop was meant to imply that the Master constructed it on Earth, and it was deliberately made larger than the Doctor's sonic screwdriver. Like the Doctor's screwdriver and Sarah Jane's lipstick, the Master's laser screwdriver was also created as a children's toy with sound effects. The laser screwdriver reappears in The Doctor Falls when the Master encounters his later female incarnation, Missy. Again, his screwdriver acts as a weapon, the Master using it to destroy a Cyberman and to kill Missy, shooting her in the back after she stabbed him in the back.
In the series 4 episode "Partners in Crime", the antagonist Miss Foster is shown using a sonic device identified as a sonic pen, which the Doctor describes as having identical functionality to his screwdriver. It could, however, open deadlocked windows and compartments in the Adipose building that the sonic screwdriver couldn't. After confiscating and briefly using it, the Doctor throws the sonic pen into a bin. The sonic pen took the form of a sleek, black and silver fountain pen with a blue light at the top and was made into a toy version which was paired with the sonic screwdriver.
In "Silence in the Library", Professor River Song possesses a slightly bulkier sonic screwdriver, which she claims the Doctor gave to her in his future. The Doctor mentioned that he does not give his screwdriver to anyone. In the following episode, Professor Song mentions that her screwdriver is augmented with a "red setting" and "dampers". It also contains a hidden neural relay linked to River Song, saving her at the episode's conclusionthe purpose for which the future Doctor gave Professor Song the device. A toy version is available. It was revealed in "The Husbands of River Song" that it was the Twelfth Doctor who gave it to River.
In "Journey's End", Sarah Jane Smith is seen using her own sonic screwdriver, or sonic lipstick to open a door on the Dalek Crucible.
In the Christmas special The Next Doctor, Jackson Lake, who believes himself to be the Doctor, carries a regular screwdriver which he claims to be sonic. When the Doctor asks "How is it sonic?", Lake replies, "It makes a noise," which he demonstrates by tapping it against a door frame.
In the series 6 episode "Let's Kill Hitler", the Doctor has a sonic cane which appears to have the same functions as the sonic screwdriver.
In the series 6 episode "The Girl Who Waited", future Amy Pond has a "Sonic Probe" that she made herself. She claims she calls it a probe and not a screwdriver because that's what it is, and to signify that she has come to hate the Doctor. Later after she has forgiven him, she calls it a sonic screwdriver.
