Firefighting has specific tasks that you need to be able to do, and one big one is being able to cut hose if you're doing wildland or wildland-urban interface work. If the fire does something unexpected or starts approaching your position, you need to be able to cut your lines and haul ass. Serrated edges sink into single and double jacket hoses much better.
The seatbelt cutter's edge is exposed on the OP's post, which ends up having the ability of hacking your pockets or anything else up on accident. Mine isn't unless I need it out, and then when it's out it's designed much better for being able to access someone's seatbelt or even just clothing to strip them down for wound care. Doesn't clog up.
There's no visible spot for a lanyard which is always a good idea for a short grab lanyard if you keep it not on a pocket clip (usually it'll just be on/in a pocket and if it's in your turnouts it's better off with a lanyard for ease of grabbing if you need it with gloves on
it's also not really designed for positive deployment and storage with gloves on, and you're basically *always* wearing some sort of gloves when firefighting
It's just low tier on design for the actual tasks that are related to knives/tools and firefighting.
