There are a bunch of knives with
slightly proud but rounded liners that are fine. Among them, the Sencut Snap is a gem. I love the wood scales. (I just gave mine a little TLC.) The action from the box was very good but like the PF818 and the Neches, I did upgrade it to Skiff bearings.
For button locks, the Conspirator and Chevalier from Civivi fall into that category. I'm still 50/50 on button locks but some of that is just me subconsciously reaching my finger for the liner/frame.

The other issue is that I prefer a detent that breaks crisply. The recent wave of button locks is better than the axis/cross-bar/clutch locks I've tried but they don't match liner and frame locks in that respect.
If you like flickable thumb studs, the full-sized Sheepsfoot Domin from Kizer is surprisingly good. The liners are quite proud and while that did stop it from being my knife of the year in 2022, it still managed to be my runner up. Between the action and the blade shape, it's awesome.
Getting away from proud liners, the Civivi Voltaic is good for what it is. I expected the extra weight from being a steel frame-lock to be an issue but with the inlays, it really hasn't been. I scale-swapped a pair of them to get both a blackout and naked steel with wood.
For something a little more premium, I like both the Beacon and the Seer from WE. The Beacon is the winner on action but the Seer is the winner on ergonomics. For thumb studs plus a front flipper, the WE Esprit is excellent.
Overall, the Kizer Gemini remains one of my all-time favorite designs. It's a little thicker but fits into the same size category as the Elementum. It's just a fantastic knife in any variation, whether the $75 liner-lock with Micarta and N690 (Mojave Outdoors exclusive) or the $200 titanium frame-lock with wood inlays and S35VN (Kizer website exclusive).
