Durable, safe and comfortable - Handao Explorer survival knife
In outdoor activities, especially for multi-day outdoor activities that need to stay away from crowds, a suitable survival knife is an important tool in your outdoor equipment. Survival knives can be used to cut and process food, cut a variety of wooden tools, dig holes or even protect yourself... But we need to remember that survival knives are tools and not weapons, and do not need cool shapes and powerful Lethality, reliability and utility are the biggest features of the survival knife.
I was fortunate enough to get a cool look with equipment, and I got the chance to explore this explorer survival knife.
About Han Dao:
Explorer's use of magnetic box, box is a direct description:
Carrying the state, ABS scabbard wear umbrella rope and leg band, handle handle rope. The silver on the side of the scabbard is whetstone, and the black on the side is a magnesium stick.
Carrying magic tape, it can be easily hung on the military regulations belt and belt of the package.
Out of Sheath, explorers can insert scabbard both positive and negative, how to like how to come.
According to my personal experience, the explorer is a full keel structure, which is an integral knife. This structure of the tool is relatively strong, can withstand relatively large torque, that is to say, can serve as a crowbar role.
The material is D2, this D2 American standard. The corresponding Chinese grade Cr12MoV, the sun gauge is SKD11. Features are as follows: high wear-resistant, micro-deformation cold work tool steel, wind hard tool steel, carbon content up to 1.5%, high chromium content 11.5%, after heat treatment hardness up to 60HRC. D2 steel can be used to make cold work die steel with large cross section, complex shape, large impact resistance and high wear resistance, such as silicon steel die, cold cutting scissors, trimming die and so on.
Speaking of SKD11 die steel, I am very familiar with it. Before the company, it was stamping. After my hands skd11 material accessories, there are probably a few thousand. I was given the impression that the performance ratio was not enough, although not as high-speed steel as SKH51, but it was much better than the most used Cr12-based die steel (usually: luo shier). Oral life or impact resistance, there is a benefit is very stable, anywhere you can heat treatment is very good (Do not underestimate the heat treatment, a large part of the mechanical properties of the material is determined by the heat treatment. Heat treatment there are many tips , we are all high-speed heat treatment factory fittings use, the heat treatment plant determines the heat treatment process, can make the accessories performance better).
E.g:
Just this D2 (skd11)
1. Use under "quenching + tempering" condition (common use)
2. Use in the "quench + cold + tempering" state (for high precision and dimensional stability requirements)
3. Use in "quenching + tempering + nitriding" state (for high surface hardness requirements)
4. Cryogenic treatment For maximum hardness and dimensional stability, the mold is cryogenically cooled immediately after quenching -70 to -80°C for 3-4 hours and then tempered. Cryogenically treated tools or molds are harder than conventional heat treatments. High hardness 1-3HRC. For parts with complex shapes and large dimensional changes, there is a danger of cryogenic cracking.
5. Nitriding treatment After the nitriding treatment of the mold or workpiece, a hardened structure with high hardness and certain corrosion resistance is formed on the surface.
6. Nitriding treatment at 525 °C, the workpiece surface hardness of about 1250HV, nitriding time on the impact of the layer shown in the table below. Nitriding time (hours) 20 30 60 Nitriding depth mm 0.25 0.30 0.35
7. Soft nitriding at 570 °C, the surface hardness of the workpiece is about 950HV. Usually soft nitriding treatment for 2 hours, the depth of hardened layer can reach 10-20um.
Therefore, when we measure the tool material, we can't just look at the model of the material. We also need to pay attention to the heat treatment process. Different heat treatment processes of steel, the mechanical properties are really quite different.
For field survival knives, single-edged flat edge is the best choice because of the need to pick firewood, make traps, deal with prey, etc., and it is relatively simple to repair with broken ones, and single sided edges are safer to use. Good-looking tooth-edged knives are more often used for search-and-rescue types of tasks because they often need to cut tough fibers such as clothes, seat belts, ropes, etc. Most importantly, the cutting edge cannot be ground.
The knife has a certain thickness and can withstand grinding, digging and crowbar use.
The tip of the knife looks like a strong puncture.
Sure enough, more than 20 cm of free fall was pinned.
Anti-slip hand pattern
Carry:
The back waist is horizontally inserted, so that it is the most low-key to carry. Under normal circumstances, it is not possible to bring a guy and it is suitable for people.
This is naturally the case in the mountains:
If you have a tactical bag on your back, you can also hang it on the bag.
Or on the strap.
The center of gravity is in the forefinger groove, and the control is very good. The weight of the dog's leg is in front of the knife. Although it is hard to cut, it is really hard to use.
The main point of the survival knife is resistance to exercise, that is, good retention and grindability, and the sharpness is placed second (cough cough ...) so I do not cut paper and shave anymore.
However, cutting a wooden stick is still very easy.
In fact, the roots above the pile are bamboo. After cutting a few knives, the titanium coating of the blade is a little spent...
The blade is not sharp enough, but the puncture is still very good. A shotgun or harpoon in the field should be leveraged.
As mentioned above, explorer's scabbard comes with a magnesium stick. I dare not try this on the mountain this season:
The fire material did not find a reed-like material, but only a paper towel in the store was torn off. The harder one was. It took a long time for Mars to fight.
Magnesium consumption for ignition 2 times.
Because Explorer has a window breaker at the back of the knife handle, I couldn't find the windshield of the car. I used a beer bottle with a strength much higher than that of the common glassware.
Sure enough, the knife breaks into the bottle, and the ability to break the glass is beyond doubt. Let Explorers in the car not afraid of the car accidentally fell into the water.
Broken window handles after breaking jiuping only faint traces, tolerance can be.
to sum up
Choose the three elements of survival knife, Handao explorer survival knife is very consistent:
The first element is tolerance.
Straight knife, full keel.
The second element is security.
Make sure the knife can be carried easily without hurting yourself.
The third factor is comfort.
The handle should be comfortable, even after long hours of heavy work. Choose a sturdy handle and hand rope hole.
So I think the Handao Explorer is a very good outdoor survival knife.
The cup is opened with one button, lightweight design, multi-color optional, long-lasting heat preservation and cold preservation, 304 stainless steel, safe to use. Sealed design, free to choose not to spill, the inner side of the lid is sealed with silicone ring, so it will not spill easily.
