There was this movie where this retired crazy commando made his knife from scrap metal. I more or less fell in love with the design and wondered what metal would be best to make such a knife.
i read somewhere that the blade-springs from old cars would do because this metal is not brittle and will not break easily. Unfortunately is will not keep its sharpness when frequently used.
Do you guys have an idea what scrap-metal to look for when making a good survival knife such as the Becker Companion?
While I am at it.....any tips for how to proceed scrap-metal knife making?

well he turned me on to several dozen fins from this generator... pure titanium... 3 feet long 3.75 inches wide and 1/4 inch thick...
I thought they would make the perfect knife blades... BUZZ... Wrong answer....
So far I've gone threw three grinder wheels and still don't have the roughed out shape yet... for now I've given up until I find another way to cut and shape those titanium slats would make an awesome blade but... I guess I just need to rent time with a CNC if I'm ever gonna get em done...

C&C won't cut it, you'll destroy every bit in the shop.
Wire EDM machine is what you''ll need to rough out a blank.

The movie you are referencing is probably " The Hunted" with Benicio Del Toro and Tommy Lee Jones.
The story is loosely based on Tom Brown's experiences, related in his book " Case files of the tracker".
The Knife you mention is a WSK or wilderness survival knife, designed by Tom Brown and made by Dave Beck.
Beck WSK's run around $400-2,000 if you can find one.
Red Scorpion makes a really nice version for around $350 ( the RS-6)
TOPS makes the official Tom Brown Tracker in 3 sizes.. from around $280 for the big one. ( IMHO, the tops versions are not as good as the others.
The steel used for these knives are usually 1080 spring steel ( like used in leaf springs for cars).
In the movie, Benicio Del Toro forges a knife in a fire, from leaf springs on the side of a cliff, in the woods.
This ain't happening in real life.
You need tools, a hotter forge fire than you can imagine, and a very strong understanding of mettalurgy, and knife grinds, or you'll do alot of work and end up with a pry bar.
It would also take wayyy too many man hours to even attempt something like this int he wild.
It can be done.. but I make knives and I won't even attemp this in the wild.
BTW, it's a great movie. One of my favorites.
If youve never seen it, take a couple hours and watch it.

I've made crude knives at work for cutting various things. I've made SS knives for cutting K-Wool which is an industrial fiberglass insulation for gas turbines, using a plasma arc to cut 1/8 th inch stainless, and a 4 1/2 grinder with a sanding disc, pretty simple really. Nice thing about stainless, it holds an edge longer and it wont rust on you.
Carbon steel is obviously a little easier to work with and cheaper/easier to find. If I wanted to make one right now, I would just go out to the garage and grab one of my old lawnmower blades and cut it down to whatever size I found appropriate.
If you have the tools and time, its fun and not hard to do.
