On the Leatherman front, I have the Wave, Skeletool, Juice XE6, 3 juices (PS4, P4, S4) and the micra
I also have 2 Victorinox Swisstools (scissor and non-scissor versions), a Gerber something that I can’t remember, and a few other randoms
I used to keep the Wave with my bike stuff but realised I don’t need the full weight of it. I now carry the Skeletool on my bike, scissors would be happy though (zip ties, cutting packaging and plasters). The PS4 would be quite good on the bike as it’s small enough and functional enough to be worth it
The Juice series is good if you want something non-locking, the Wave or Skeletool would get my recommendation if you want something locking. The Swisstool is the best quality overall, but it’s the heaviest too
