Question: how long is the knife?
Document: This is a cool kit it is also well constructed so it should last a long time. The items inside are very useful back up items to a knife and a steel container. The only thing i would like to see added is a sewing needle.
The knife is very sharp and could easily be fixed or tied to a stick to make a handled blade. The fishing line and equipment is more than long enough to make a primitive fishing pole from. All in all this is a very good quality kit that can be carried with an emergency bag or by itself if your not able to carry much. I will probrably buy another and would recommend this to anyone who understands the need to be prepared for anything.
dobbers), knife blade all wrapped in the externally visible 500 lb paracord with attached carabiner.
I bought several of these. Opened the first one and was pretty impressed how it was packed. Knife and fire steel work ok just don't cut yourself !!! !
I found this to be very handy , very well build , looks like this will last a long time. only thing is have to order another one cause I opened this one
Bought this item for my father in law (the man who has everything) and when he saw it he was like a kid in a candy store! I'm waiting to see how long before he opens it and uses the nifty things inside!
I read that every person should have a length of rope, and small pocket knife and a way to start a fire on their person at all times...it's all here - amazing! The knife inside this product is just a knife blade, so I did also purchase a separate pocket knife, but the fact is that it's all here in a small, neat package - very impressive!
Under the foil is a zip-loc bag with the contents and the tinder is double bagged in another zip-loc.The fire starter is a thin rod, difficult to hold, but does the job. The knife blade can be used to scrape some filings into the tinder and a sharp strike will cause it to spark.The foil is a little thicker than standard kitchen foil and measures a decent 380mm by 290mm (approx).
The single best &#34;Survivalist&#34; item you can buy, well besides a well-made knife that is. Just one sentence of wisdom, DO NOT OPEN THIS UNLESS YOU NEED TO OR CAN RE-WRAP IT. Also it's smart to keep the tag that comes with it on, the tags reminds you whats in it. For the times when you're panicking and don't realize what you need is in there.
I originally purchased one of these for myself and loved it so much I got one for my husband for his birthday! It makes me feel confident knowing I have some essential survival supplies right on my keychain. It is very solid and wrapped extremely tightly. I have no doubts it will last a long time. It arrived quickly and I am very pleased in the quality. Thank You!
