This is not the first time I started VOLLSION's product. I used to play VOLLSION titanium alloy finger tiger gyro. This test is a VollSION thorn titanium art knife, which actually belongs to the category of EDC toys.
Compared to VOLLSION's tiger gyro product wooden box and tin box packaging, this utility knife's packaging is relatively simple, design style is tough, there are a variety of surface treatment models. The evaluation is the old sandblasted stone washed surface.
From the accessories are also more real, including trapezoidal blade 5, spare spring 1, 7-cell umbrella rope 1 meter, all in a transparent plastic box. The box's workmanship is also good, the box wall is thicker, the toughness of the material is also very good, the subzero temperature has no obvious hard feeling and should be very durable.
From the size point of view, the length of hedgehog collection 70 mm, open the longest 92 mm, 26 mm wide, 5 mm thick, the total weight of the blade is only more than 30 grams, is a very portable and compact mini utility knife.
What are the characteristics of this hedgehog utility knife? Personally combined with hands-on experience, summed up four characteristics:
One is TC4 titanium alloy material. Anyone who knows a little bit about titanium alloys should know that titanium alloys do not rust (more stable than stainless steel), have a low density (about 70% of steel density), have high strength (flat with steel), and can be baked blue Color and other advantages. However, in fact, titanium alloys have the same series as stainless steel. The common TA2 is industrial pure titanium. The hardness is similar to that of aluminum alloy. The TC series has the same hardness and strength as steel. The most common ones are TC4 and TC21. However, TC21 processing is too difficult, and the price is more expensive, so our common high-quality titanium alloy is basically a TC4 product. This kind of material is made of EDC pieces. Generally small bumps do not have any traces.
The second is integrated processing. The so-called integrated processing actually refers to the knife shelf is an integral processing, playing ordinary utility knife should be more understanding, ordinary knife art knife is generally a semi-wrapped steel roll structure or front and rear cover screws fixed forming the fastening structure, This is a relatively low-cost solution. It does not need any CNC technology.
Then the integrated structure, in fact, is made through the groove in the middle of the entire titanium alloy plate, forming a fully wrapped structure. In addition to the CNC process surface, this process will also use firework perforation, wire cutting and other processes. That is, a centered insert groove with a depth of 7 cm and a width and height controlled within 0.1 mm (10 filaments) is to be cut on the titanium alloy plate. Considering that titanium alloys are inherently viscous, this is a test for the process and it is the reason for the higher processing costs. In fact, this hand knife, I think the processing accuracy is very high, the center of the seam is very good, and the gap between the blade and the knife holder is very uniform, the estimated accuracy is within 10 wires.
The third is a replaceable trapezoidal conventional blade. The replaceable blade is not the bright spot, because I haven't seen a utility knife that can't change the blade yet; but as the high-end utility knife, can replace the regular blade, this really is the bright spot. Because the blade is originally a consumable item, if it is not a normal specification, it will virtually increase the use and maintenance costs of the utility knife. This blade uses a blade size of 60 mm in length, 19 mm in width, and 0.6 mm in thickness, and can use the Starcraft 93434A Trapezoidal blade of the same specification. Shida is relatively a big factory. This kind of blade is 10 pieces and a pack, which also means a price of no more than 15 yuan. That is, a blade is more than 1 yuan and the replacement cost is very low. Therefore, this utility knife can be used without worry, do not worry about the blade can not buy or expensive supplies can not afford.
Workmanship details
From the detail point of view, sandblasted stone washing process makes this titanium alloy knife more durable, not easily affected by scratches and bumps affecting the aesthetics, can be bladed with good neutrality and visual impeccable. 
The shift knob adopts the spring button design, and the material is also TC4 titanium alloy. The thumb pressing surface also has a radiation-like texture processing, and the shifting adjustment feels good.
The following is the parts drawing after dismantling. The spring, as a possible loss component, is also sent one more.
The following is the assembly diagram of the shift knob. Actually, after shifting, the rear cross screw must be locked. If it is not locked in force, the blade will be topped back. However, in fact, there is no ordinary utility knife to adjust the file.
From the details of the knife rack, the opener design of the tail makes a bright spot, while the triangular arc corresponds to the front of the knife head, which also increases the aesthetics. The description of the anti-slip groove on the back rib, the design of the subsurface groove on the plane, and the design of the three-way light-transmitting small groove design also make the practicality and aesthetics improved.
However, I prefer the sling hole design, which makes it possible to hang the pendant or hang it on the key chain. This trial sent the umbrella rope but did not send the knife, so I simply hang my titanium horse EDC coin. Going up, it is estimated that this EDC coin with a value of nearly one thousand yuan is worthy of the utility knife. The utility knife should feel honored.
If you decorate it, it is estimated that the following effect, and do not blame old brother like colored rope.
In fact, many EDC toys are not practical, such as Ray's hammer, titanium alloy crowbar, fingertip gyro, and even a large part of the tiger, are crafts or playing pieces. However, in addition to the utility knife, practicality is also possible.
First of all, it is very convenient to receive express delivery. For online purchasers, the average daily delivery of a delivery is not too much, many people are receiving a bunch of express delivery. This is a quick unpacking inspection, but it is most convenient to use it. Two grades of blade adjustment can ensure that only the outer package is quickly cut, and the beloved object is intact.
The bottle opener is actually more practical in summer because it is like going out on a picnic or eating a barbecue. Blowing beer is a common practice. It is more convenient than using other tools. The actual test opening is not as easy as an ordinary bottle opener, and the white can be fast, because the chin of the bottle opener is relatively short. However, using proficiency in the estimation can also bring up the speed, and it is also possible to open a bottle of magic show. 
The sharpness of the cutters is basically not tested because the hedgehog actually uses a universal blade. This type of blade uses the Japanese SK2 carbon tool steel. The steel has a high strength and is better. Wear resistance, sufficient toughness, made of thin blades after the cutting ability is relatively strong. I actually used it to test the jujube roots and shrub branches, and the sharpness was good.
After several days, it was later tested by cutting fireworks and cardboard cartons, plastic bottles, etc. The sharpness of the knife edge was still good. At present, the first blade has not yet become dull, but it is too thin and has collapsed. The condition of the blade. Fortunately, there is no need to consider the matter of sharpening.
From the force point of view, this 7 cm blade holder and 2 cm blade are indeed mini-points. In the cutting of high-toughness rubber triangle belt, it is not very handy in use, and there is no good focus point and finger pushing position.
This is the reason I used to use tactical folding knife! But what can this explain? The tactical folding knife is easy to use but cannot be commuted. Fingertip gyros, tigers, EDC crowbars, and tactical pens can be carried but they do not have tool functions. This titanium alloy utility knife has only one-half the weight of a normal fingertip gyro, and one-fifth of the length of a normal tactical knife. It can be estimated by carrying a train on a subway train. This is what makes it more portable.
In short, this is a titanium work knife with good workmanship and good finish. It is estimated that tool lovers can't resist the temptation!
Well, this evaluation is over. Welcome everyone to leave an interactive message.
