About 20 minutes and he is better then you or I are likely to ever be. Although part of that is because he did not have any really easy resources in range of his house (like birch).
Lessons learned….
1. This is why you carry tinder if you can. Saves a lot of time.
2. Tie something high vise orange 550 cord or something like that to your ferro rod. You can’t rely on not being an idiot when you are under pressure.
3. If you can have a fixed blade knife on you it will work a lot better when you really need a knife then a folder.
4. All that said, you don’t need much to get a fire going if you have time. When you are short on time that is what makes skill and gear so much more important.
