The closest that fits for me in the KAI lineup is the ZT 0350 but may not be enough of what you are looking for. I really like that Cyclone shape/style with the wide but short and with thin-ish handles. The 0350 is a more general purpose design, the G10 is grippy and doesn't get cold, and I think you'll like it even if it doesn't have that chunky style and slick handles.
I wish the One Ton had G10 on both sides, like the Tension but with the original blade shape, or full metal something like the Boker Anso Albatross. I also like the micarta handled Boker Blackwood Pipsqueek and the Benchmade Sibert MPR both are thicker. The MPR has the benefit of being both Oregon designed and Oregon made, if such things concern you :highly_amused: There are also the custom/midtech versions of those production knives as well as the monster Direware Solo.
