Having snapped a couple of the popular yellow plastic levers, I needed something that would be bombproof out in the backcountry. These plastic-coating over metal core levers are just the thing for working with fat tires. I use them for 650B gravel tires. Heavier than the plastic ones for sure, but they will never break.
They are not cheap - but if I consider how many cheaper tire levers I have consumed before they are a good value and will not let you down - especially with tubeless tires that tend to be glued to the rim.
