ABOUT COMBINATION KNIFE/SPEAR BLADES

Holly shades of Moby-Dick Batman; that there is a really, really impressive looking piece of useless junk; maybe we should start one of those buy one get one free-just pay additional processing and handling deals . No, but, really, really, I am very, very, exceptionally, depressed with all the new variations of the medieval battle axe sledge hammer, and this "survival???harpoon/knife???/spear head; but, of course, as with all such really, really, really great inventions, there are a few minor, very,very, slight, mind you, nothing to worry about; at all--very minor-problems.
They are:

•  You now have an implement, that required a lot of time and effort to manufacture (probably burning out a few drill bits, and grinding disks); taking up valuable room, and adding weight to your survival kit, that is really not practical, or of much use, for anything; and that could; well be; one of the contributing factors, if you fail to survive.
• There are, of course, exceptions to every rule, ( a broken handle for which the wrap is used as a temporary repair) but generally speaking, because for many of the chores you are apt  to be using your knife for; you will want it to be easily cleaned and kept in at least a somewhat sanitary condition so a wrap, of any kind, is most undesirable.  
• Parachute cord, is made of nylon, nylon is basically impervious to water, soaking will not cause it to stretch.
• Either the "inventors/designers of these implements/tools know very little about actual survival techniques themselves, or they are more interested in selling a product than they are about YOUR survival.
• A true knife is never used for chopping, it  is not an axe, machete, or spear,  and you never want to treat one as if it were.
• In this contraption, you do not have a knife; or any other implement; that is serviceable or useful for much of anything.
• You are not going to NEED a metal spear head.
• This THING does not have enough heft or provide enough leverage for chopping. It is not a boning, or skinning knife, and it would be almost useless for meat cutting. In other words, in the PRACTICAL UNCOMPROMISING WORLD OF REAL SURVIVAL, this contraption/THING is almost useless, unless, possibly in a much smaller version, and used as an improvised fish HOOK.

But, don't take my word for it, follow the three links below and watch a real expert, at work, in what most of us like to imagine; is a common, and  absolutely necessary, bushcraft/ survival chore--that of cutting up big game--well almost; then decide for yourself whether or not your choice of a field/survival knife is a good or wise one.

NOTE: HE USES ONLY--1-- KNIFE--NO BATTLEAXE, CLEAVER, MACHETE, OR SAW; AND YET HE BREAKS DOWN AN ENTIRE SIDE OF BEEF, FASTER THAN MANY MEAT CUTTERS COULD, USING A POWER BAND-SAW.
