fancypenYou can buy a replacement ferro rod insert from Light My Fire or drill/file it out carefully and glue in a replacement from a third party source.
It is a great knife for the price if you want an all-in-one but the ferro rod is on the narrower side and the tang of the knife is reduced.
If you want to baton wood or use it fairly hard I would recommend using another knife that has a longer or full tang and combine it with a separate ferro rod.
