Light My Fire firesteels have a reputation of being the best firestarters available.
I already have an 'army model' version of this firesteel, the only difference between the army vs scout version is that the scout version in somewhat smaller & is good for 3,000 fires compared to 12,000 from the army version.
The black paint on the steel 'key' should be scraped off first using the smaller striker key to expose the metal underneath, then you are ready to make fire!
I normally use cotton wool coated with a little petroleum jelly (vaseline) to catch the sparks & get the initial fire started then start adding wood shavings & smaller sticks etc to really get the blaze going, I even use this to light my barbecues.
Highly recommended to any budding boy scout & will certainly last for a good few years even with regular use & available in loads of colours. Lovely Stuff!!
