No a flint and steel is easier to make a spark. You’re carrying steel for wood cutting, food prep etc You gather tinder when dry and carry it for when it’s raining.
I carry depending on trip a Toaks 550, Alpkit Kraku, MSR Peizo, Snow Peak Hot lips, Primus 100g canister, Jetboil canister stand.
My knife I keep a firestarter as a backup if Peizo doesn’t work.
If I’m truly intending to cook I’ll also nest a wider pot such as a Toaks 700ml.
If just for day hiking or overnight I’ll switch to alcohol cooking as lighter smaller, 60ml will do a dinner+breakfast, but switch to mini Bic lighter as harder to light with ferrorod, with ferrorod as backup. Alcohol is harder to fail but gets heavier than gas for more than a few days, and hates wind
If an overnight I’ll not pack a charger just a 10000mah Anker Powercore
