A differentiation should be made between scratch cues more generally (which can take any form) and scribe cues made using a Clint Phare style scribing tool. I've always called those scribe cues and handmade cues scratch cues.
A discussion of cue placement (especially 1.85 vs. Scope) should be added.
A discussion of click cues (both tape and cement) should be added. --JesseCrooks (talk) 19:43, 23 March 2020 (PDT)
Changed the image captions after taking into account the above suggestions. Added image of handmade scratch cues. Rlyon (talk) 15:17, 25 March 2020 (PDT)
