One of my first publications was a knife on a string.
I had to listen to such a stormy negative assessment from the participants of the site, and even today, some will not calm down.
The essence of the negative is that this is nothing at all (mildly).
Let's try to figure out the example of this knife with a rope, in essence and benefit, as well as plagiarism (if any). I'll start with an unusual example.
About the horses.
Once a man tamed a horse for his needs, an assistant in the performance of hard work. I will not go into details (I hope you know them), but the horse will not be lucky until you feed it well.
Horses were fed with herds, usually grazed at night, worked during the day. It was unprofitable to graze one horse, and they thought of tying it to a rope and “pinning” it on the meadow. The rope began to serve as a guard (shepherd), so that the horse not lost.
Initially, a horse was driven behind the same rope when working, it was called "under the bridle."
How is Nekrasov ...
Let's continue about the rope. And whoever came up with the second rope to tie to the horse was called them reins. Which allowed to control the horse remotely. Initially, the reins were rope.
With the help of them the command of the horse was given “forward”, backward “, stop”, left and right, turn.
The notion is simple, just two ropes, but it was so successful that even after six centuries it did not lose its relevance. The point is not the complexity of homemade work, but its simplicity and usefulness.
Let's move on to the knives...
A knife for human survival, played in life can be said to be one of the main roles. To lose a knife, to remain without hands (such was the expression).
Therefore, the knives that a man had to carry with him were tied so as not to lose. On a rope, on a leather strap, on a chain. Wearable knives had special for this fixtures (to attach a leash to a knife).
If there was no fastener, we did it ourselves ...
My knife rope performs two functions at once,
1. Not to lose (like a horse), a thing known to all (they poked me with this)
2. Quick and easy to govern (like a horse again)
“threw out” (but did not lose) “the movement of the hand and knife in the palm of the hand, ready for work (that is, also controlled).
"Threw away" ...
[
"Ready for work..."
This is the essence of innovation. And no matter how you try to "boo" this, you will not find anything similar or similar. The fact that it’s kind of dangerous and you can get hurt with a knife no more than just manages to fall on a knife that is not tied.
And for a complete sense of the usefulness of such a rope, you just need to make and test it in action, then draw conclusions and determine the significance of what was invented. And do not boo indiscriminately without understanding the essence.
The conclusion is obvious, homemade is especially valuable. simplicity and utility.
Novelty about knives "my assistants".
As a long time ago, the need for such or something like a "helper" was brewing. Butchering a carcass of a chicken or duck, and especially a goose, as well as cutting a large fish for cooking, that is, chopping it into pieces, let's say the task is not easy for a man, let alone a woman. For this, we use a soda pruner, a kitchen hatchet for this.
It’s very difficult and decent power is required, I’m not talking about all kinds of bloody splashes from meat.
I do not claim authorship, I have not read anything like it, but these are all trifles.
To solve this problem, he “attracted” a kitchen hatchet, quite weighty and made of good steel.
He sharpened the butt immediately, as did the main "sting." Use for more stiff bones ...
Made a base from a strong oak board ..
He prepared, sized two suitable building corners and screwed them to the base ...
A bolt, a spring and a nut (not 8) were found in gold reserves ..

Secured the hatchet in the eyes with a bolt, spring and nut ...
The hole in the hatchet was finished at 8.
That's all! When testing the design, the soul rejoiced. Doing work has become much easier, more convenient, easier, cleaner. No great effort, no splashing. If the piece is large, skip the cut between the eyes and cut further, as you cut for example metal, with scissors. If earlier this work was "hard labor" for me, now it’s a pleasure.
By the cleanliness of the manufacture of the structure, it did not sharply drive, I wanted to test it first.
Well, perhaps that's all. The result was a whole lecture.
I will answer questions, if any. The author is in place.
