I can't see what tool you are citing in your original post, so forgive me if this is irrelevant to you.
The black coating on the Cold Steel machetes does a good job keeping rust at bay. Once you get a good edge on it with file and stone, you can cold blue or Rust-Oleum the shiny edge to further the protection.
The Cold Steel machetes are almost bulletproof. They range from 2 to 2.8mm in thickness, the 2mm blades being whippy in longer versions. Stay with the thicker ones as it really makes a difference. The rubber grips are good, the plastic ones less so. The more gimmicky a CS machete, the less practical it will be. As above, the Thai machete could be an effective fighter against an unclothed enemy, but I don't know I'd want it in the field. Perhaps the only gimmicky one I'd like to try is the smatchet machete, but only because . . . well . . . 'cuz SMATCHET! The other I'd like is the Bowie machete, but that's a pretty straightforward design.
I have the 17" seax machete, and while it's technically a gimmicky CS machete, it has the rubber grip, full tang, thicker blade, and easily recontoured point if that's something I feel like doing. But I haven't needed to do it. It does everything CS's beefy, stern faced, blade-abusing video orcs say it does.
Occasionally CS discounts their machetes to the point they are impossible to resist. Check out their ltspecpro.com website for the best deals (Mods, is this OK to say?).
