I have bought a shit ton of random knives (Helvie, drake, GEC, flexcut, morakniv etc) based on recos from subreddits and youtube videos and I have to say despite how cool they are, I think my favorite go tos are a Victorinox tinker that I redid the edge on and a Remington whittler I bought on eBay because the price was right.
I'll have to check when I get home, it's roughly 6" and has a swivel collar to lock the blade. Cylindrical wood handle with some shaping for comfort.
