Description says only good for non-ferrous metals...mild steel at best. Hooks are generally hardened carbon steel. For $14.99, I wouldn't expect much.
It's not only important to have a good set of cutters for the health of the fish...it's also important for you or someone else on the boat. If you get stuck by a hook from a thrashing Musky, and have to cut off the point of a 7/0 3X hook...you'll quickly regret having sub-par tools. Been there, done that...have the scars to show for it...
Btw, those Crappy Tire special Red Wolf cutters are useless...
Unfortunately, Musky fishing doesn't come cheap...keep an eye out on Kijiji or FB Marketplace for someone selling their used gear...that's about the only way to keep the price down
