Make one.
Step 1 Buy a pack of flints from a tobaccanist (6flints 49p) and some araldite from pound land (£1.00 !!) a broken hacksaw blade and an old garden cane.
Step 2 Get a piece of garden cane 6" long and cut a groove about 1 1/2" long at one end.
Step 3 Mix araldite and put into the groove you have just made, now place the flints in the araldite end to end make sure you cover the flints with the glue and leave to dry or 24 hours.
Step 4 Take the hacksaw bladeand and brake about 2" o one end, scrape away the top layer of glue with the back untill you get down to the flints, you now have your very own firesteel, use a piece of cord to fasten the blade to the firesteel and use as you would a shop bought one.
Step 5 Eat a meal or just keep warm. Enjoy
