Now for the supplements.
Because not blade length of the blade in the above description, 10 cm.
The fire steel in the knife handle is more of a gimmick used in my opinion, than practical. He simply produces too little sparks. For making fire I take her to "Light my Fire BBQ" Firesteel, larger striking surface, beautiful handle, more sparks.
The knife in any case deserves 5 stars, I was only four, because in the description is that a whistle shall be readily available, which is not true.
Therefore please change description.
