As a guy who runs Gator skin tires on carbon wheels I appreciate a strong tire lever. So far these have been great and have handled me using all of my strength to install Gatorskin tires on these rims without damaging the tube, tires, rims, or levers.
Carry these in my duffel for whenever the need arises. Too heavy to carry on my bike but they are with me often in my truck. If I did need to use them in camp then figure the stiffness would make it a little easier than the standard plastic type.
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.
