I currently have all of the Character Options stuff:

- The Third Doctor’s first Sonic Screwdriver (the newest, most accurate release)

- The Third and Fourth Doctors’ Sonic Screwdriver

- The Fourth and Fifth Doctors’ Sonic Screwdriver

- The Eighth Doctor’s Sonic Screwdriver

- The War Doctor’s Sonic Screwdriver

- The Ninth and Tenth Doctors’ Sonic Screwdriver (newest, most accurate release of the Tenth Doctor Sonic Screwdriver)

- The Tenth Doctor’s second Sonic Screwdriver (best you can do for this is putting the emitter core from The Day of the Doctor release of the Tenth Doctor Sonic Screwdriver, which is the first to feature the yellow wires inside the tube that are in his prop used for seasons 3 and 4, and easily put it inside the handle from the “wave 4” release of the regular Tenth Doctor Sonic Screwdriver, which was the last one on this list)

- The Master’s Laser Screwdriver

- Sarah Jane Smith’s Sonic Lipstick

- Matron Cofelia’s Sonic Pen

- River Song’s future Sonic Screwdriver (the most accurate release of this one - the one that has both a red and blue setting and the neural relay light feature)

- The Eleventh and Twelfth Doctors’ Sonic Screwdriver (the touch-control release, which has the spare power cell 12 throws to the soldier to swallow in Into the Dalek)

- The Twelfth Doctor’s second Sonic Screwdriver

- The Thirteenth Doctor’s Sonic Screwdriver (the Character Options version sold in Britain is more visually accurate to the device seen from the concept art, photos of Rubbertoe’s replica version, and what can be seen from leaked images online, but I might end up getting the Seven20 version sold in America, too, because it has the rotating emitter and looks pretty nice)

- The Doctor’s Psychic Paper

- John Smith’s journal of impossible things

- The Doctor’s Nano-Recorder injector

- Jack Harkness’ Vortex Manipulator

- Sarah Jane Smith’s Scanner Watch

- The Corsair’s Psychic Container

- The Chameleon Arch fob watch

- The Master’s special signet ring

- Sarah Jane Smith’s Arcateenian Communicator

- A Judoon species scanner

- A Cybermat

And an Adipose and Mr. Huffle from Wow! Stuff and Ikon Collectibles, respectively

I am aware of Character Options’ custom, non-canonical creations, like the Trans-Temporal Sonic Screwdriver and Anti-Time gun, which look cool, but I am only interested in things that have been in the actual show. The other psychic container they have, the one with random Gallifreyan symbols as opposed to the Corsair’s ouroboros is also non-canonical, I think, as I don’t think any of the other psychic containers they show in the episode they appear in have any symbols on them at all.

One thing I’m not sure about is the remote-control K9. Would that count as this sort of thing? I’m thinking not, because he’s not roughly a similar size to the actual K9, but much smaller, isn’t he? So I would add that to the collection for the same reason I wouldn’t add an action figure of one of the characters or little model of the TARDIS. Is that fair and true?

I saw Thirteen's Sonic in Hot Topic, Fellow Whovian.

That would be the Seven20 version, then, I believe. Nicer features than the Character Options version, but not quite as visually accurate in its design differences!

What about sonic sunglasses? Or sonic cane??

They’ve unfortunately never made ones of those items :( I do think there are some of the fancy, expensive, handmade prop replicas for the cane out there somewhere, though, but probably no longer available. As for the sunglasses, I actually do intend on getting a pair of Ray-Ban original Wayfarers to match that look, haha, but that wouldn’t quite fit the type of stuff I’ve got on this shelf
