Men love knives like women love bags. Tactical knife is not only the main tool for outdoor self-defense and survival, but also the object of EDC player collection. As an EDC lover, I used to post many articles on the Internet, but I'm still attending the tool trial for the first time. I would like to thank the cool rabbit flop, thanks to the cool platform and tekut. Manufacturers provide trial products. Dick is a relatively young brand, the English name teku is taken from the cut harmonics, represents the "to cut for raw" product design concept, before the two ZERO and TOUGH two EDC knives, cost is not bad. The Tiburon tactical folding knife introduced this time also inherited the low price and practical product positioning. The specific parameters are shown in the figure below: 
Unpacking
From the packaging point of view, sharks use plastic transparent soft box packaging common to digital products. The packaging design is not bad. Without opening the box, you can see the whole state of the folded state. Inside the box there are instructions, product maintenance, screw adjustment, surface coating Layers, polished warranty, etc. were briefly introduced. The normal use of a lifetime warranty, 2 years of free polishing and other services are also relatively warm.
The folding knife weighs 155g, but due to the relatively wide blade design, the overall impression given by the closed state is relatively generous.

The following is the full picture after opening ~~~
The shark product has a unique number. This time, the equipment has been equipped with a cool laser mark, which feels more memorable.
From the perspective of the blade, the blade material is Sandvik 12C27 steel from Sweden Sandvik. This steel belongs to high carbon stainless steel and has a low alloy content. It is often used as a blade material for hunting knives, pocket knives, high-end kitchen knives, and tactical knives. Hardness range Generally 54-61HRC, high toughness, excellent sharpness, and has a good anti-corrosion properties; in general performance is similar to 440c, AUS-10. Knife type adopts the traditional design of dripping knife tip + false blade, but the appearance is not really good for the other products I have on hand, and the design of the blade tip wide bottom is a bit bulky.
View from the handle, the use of G10 material, G10 material hardness is relatively high, anti-deformation is strong, is a commonly used utility tool material.
The opening and closing adopts a one-piece back quick-opening fin j structure, and the knife stick is also relatively thick, and the overall design is designed around practical and durable.
The integrated quick-opening fin structure is actually a part of the edge of the fin. When the fin is in an open state, the fin can play a certain role in protecting the finger from the edge of the blade. This prevents the object being cut by the cutting blade from touching the finger in a practical process.
The following is a three-dimensional illustration of the blade with a slight tip but generally on the centerline of the knife axis.
The blade ridge is relatively thick, without chamfering and trimming the wire. The advantage of this is that the blade is further protected against attack.
Of course, the disadvantages of doing so are also very obvious, in addition to the poor appearance, the closed state without a glove holding a little bit pickpockets.
There is nothing good about locking, this structure called pad lock or wire lock is a common structure in middle and low end knives.
The shank tail is fixed with an independent double column structure, the fancy beading is slightly smaller than the shank, the diameter of the shank is about 3.5mm, and the thinnest point of the string is about 2.5mm, which is firm and firm.
This product has a bright spot is the back clip stretchable design, not shown in the figure, in fact, the clip is sliding, you can pull out about 15mm, this idea for the hidden carry out to be worthy of recognition.
Test articles
For the knives, I personally do not really want to use violence and actual evaluation after the arrival of new products, because even the best blade and shank materials will cause wear marks after high-strength use, for those who collect tools is Very taboo. However, as far as the knives I have started, as long as the evaluation report is issued, it is basically a violent use or actual evaluation. The purpose is to better display product features and give everyone a more authentic and trustworthy experience to share.
Let's take everyone to experience the quick opening. This one-fin design and the use of a bearing system make the quick opening experience very good. Basically it is to leave the hand and the fluency is good.
When the knife is closed, the integral fin effectively protects the thumb that unlocks the lock, so that the safety of the gravitational nodding is greatly increased. The overall opening and closing experience is very good, and one hand can be controlled.
The sharpness test of the knife, the corrugated paperboard I started testing at first, this corrugated paper is 12 layers thick, the thickness is close to 10mm. At present, among the several test methods that have the most severe tool wear, cutting the paper is one of them.
The following is a moving picture made by recording the screen after cutting more than 40 knives. The sharpness of the actual test knife is also OK. The section after cutting is relatively neat.
Of course, if only corrugated paper is cut, it must not be judged by violence. I later found a waste PVB tube with a wall thickness of 2mm to test; cutting this material is more laborious, mainly because the toughness and ductility of PVB materials are good, and the shark blade ratio is better. Thick, so it can not be cut off.
However, if you cut a rubber tube with the same thickness of the thumb, you can basically do it with two blades and the sharpness is good.
For the same thickness of dry switchgrass, one-handed pushing without the use of gloves can cut half the thickness, but the overall feeling is that the edge is relatively flat and straight, with poor hair strength and a little bit of a blade feel.
In addition to cutting, this knife bladed water drop head design also gave me full confidence in penetrating squeezing, and simply took a book with a thickness of 23mm and a folded thickness of 45mm to carry out a smashing test.
The hair force is still relatively normal and the vertical twisting test is more.
The depth is about 21mm, 21mm corresponds to almost the thickness of 150 sheets of A4 paper, this performance is also quite satisfactory.
Individuals are actually very taboo to take public facilities or trees and trees for testing, but in the field activities, local materials are sometimes necessary. After violent use, I took a test from the outskirts of the roots of a big tree.
Thickness of more than 20mm, the actual cutting saw the blade is still a bit blunt, it took more than 1 minute to complete the cutting, the following is the cut section:
Fortunately, the test blade did not find any condition such as chipping, which also shows that the toughness of the knife is really good. From the re-sanding point of view, Sandvik12C27 steel is also better polished, so for out, with a simple sharpener is enough.
Summary articles
In short, the Tiburon tactical knives do perform well as a practical tool. Self-defense is a trustworthy tool for outdoor use or emergency situations. The blade is generous and solid, smooth opening and closing, and strong cutting ability. Good toughness; but the design of the aesthetics and details still have room for improvement, such as the handle of the polished design makes the water with the operation, then a bit slippery, such as the design of the ridge, can be a small angle chamfer treatment, so closed hand Feel better. Of course, taking into account the selling price in the early 200s, it was not the positioning of arts and crafts knives, and the beauty itself was understandable.
In Europe, this trial share has ended here. Members are welcome to leave messages and exchanges.
