Zoltan, There is nothing wrong with simple, homemade or used gear. Hi tech gear is merely the latest version of the same tools people have used for a long time. The bronze dagger was once "hi tech" to a man with a stone knife. A man with a box of wooden matches and a simple knife is far better than a man empty handed. With the proper training that man will likely survive as well as another with the latest lighter and custom knife.
