Hello I have found two ways you can get good tinder.
1.Try the labels from your cloths some of them like nylon fabric fire with my firesteel burning after like petroleum, first is good to scrape the label with your knife to get light fibers.
I notice you that some fabrics are treated to avoid burning so you must try to know.
2.With the back (if sharp) of your knife you can obtain light shaves from wood that catch fire very easy with your firesteel.
Enjoy
