Kamio Kaede asked, "Can't you master the skills of wielding a knife even if you have been trained since childhood?" Just like Wu Liang who killed the cold steel knife in the wolf? ”

"A close stab, a stab, or a stab, whether trained or not, is done in an instant, and when the dagger is swung out of the hand, a decision must be made in a matter of seconds.

Piercing the neck or the heart, five centimeters above or three centimeters to the right? When the tip of the knife pierces into the body, it depends on the luck of the well-trained knife hand.

Therefore, what I mean is that if no blade fragments were found on the corpse, it does not mean that the other party's knife is good, and luck also accounts for a large component. ”

Kamio Kaede sighed, "So, at the scene of the five deaths, no blade fragments were found on the corpses, except for the illusory factor of luck, that is, the quality of the knife is excellent, and it can be hard against human bones?"

At present, the best forging knife material should be high-carbon steel, you just mentioned more than 20 kinds of swords, which ones are high-carbon steel? ”

"Not necessarily." Nana Ogino shook her head, "If you don't leave a blade shard when you go to the human bone, I think a mild steel saber is more suitable for this challenge." ”

"Didn't you say that high-carbon steel sabers are of the best quality?"

"Hardness and toughness are relative, and like the density-volume formula of mass, they are two properties that contradict each other.

The material of the high-carbon steel saber is hard enough to even open the way in the mountains, climb rocks and climb mountains, but the disadvantage is that it is too rigid and easy to break; The mild steel saber has good toughness and wear resistance, and it knows how to avoid its edge when it hits hard bones. ”

Kamio Kaede nodded, motioning for her to continue.

"At present, there are not many types of sabers in the world containing mild steel, even if we are lucky, it is relatively easy to screen, this kind of mild steel saber, the knife out of the knife into the sound is small, good for stabbing but inconvenient for cutting, usually equipped in the scout sequence.

It can easily climb cliffs, kill enemies and capture prisoners, survive in the wild, and can easily pry harder objects than it can without any damage. ”

"Well-known sabers such as Mad Dog, Kaba 1217, Gurkha Scimitar, Huya, M9, Knight, etc., are all sweet and sweet in the eyes of military fans. However, the Mad Dog Tactical Assault Knife is 30 centimeters long, which is slightly longer and can be ruled out.

Kaba 1217 once shined in the icy skies of North Korea and the jungles of Southeast Asia, but with the closure of the Kaba knife factory, it has been out of production for decades. Except for some older veteran military fans, it is rarely seen on the market now.

And this kind of knife is not very convenient to carry, the blood groove is very wide, like a big iron mallet, if you take it out to kill, it is a bit too ostentatious.

As for the Gurkha scimitar, also known as the cold steel big white dog's leg, it is an improved version of the Nepalese saber, which is a heavy combat dagger, which is a good choice for dismembering corpses, but it is a bit like a cannon bombarding mosquitoes when used for close assassination. And this knife does not have an integrated lock and stop pin, it is purely born for violence. ”

Kamio Kaede couldn't help but give another thumbs up and asked, "What about the remaining models?" ”

The full name of Huya is D80-Huya, which is a special military thorn produced by Huaguo military enterprises, which can easily twist barbed wire and aircraft shells, and is also known as the king of oriental military thorns.

However, this saber is very strictly controlled in China, and there is almost no possibility of entering the civil black market, if this killer has such a great energy to get Huya, his status will definitely not be reduced to being an assassin.

M9 is relatively easy to obtain, and the local products of the rice country, a large arms manufacturer, have been sold out of the country over the years. However, this knife has a nylon pattern on the surface and a fairly long hard serration, which does not meet the characteristics of short serrations, so there is only the last style of saber left -

The Knight Sabre, also known as the Silver Killer, is an improved version of the Alaskan Whaling Fisherman's Fighting Knife and is an older dagger with an ultra-strong one-piece lock and stop pin, and a signature hexagonal screw hole on the blade for special forces firearm disassembly.

In addition, I would like to mention that the notorious Norwegian farm killer Ginise used this knife to kill more than 40 people on her 42-acre farm in Laporte, Indiana, and buried them in the yard to feed the flowers, and she also ate this ......dirty knife and fork."

Kamio Kaede nodded and asked, "Can you find out its circulation channels in the black market?" ”

Nana Ogino pouted, "It's difficult, the Knight knife was produced as early as the beginning of the last century, and I don't know how many originals and high imitations were made, and some of them are even stronger and more durable than the original." In short, there are still a lot of channels to buy, if you have acquaintances or informants in the black market, you can entrust to check them.

It's really no problem, you send a hacker to investigate the sales orders of the Americas' cutting-edge tactical weapons companies to see if any of them have been sold to Tokyo...... So I advise you to focus on the profile of that Kansai Holmes. ”

The three of them argued about the saber for a long time, and finally decided that the murder weapon should be the silver killer produced by the American Advanced Tactical Weapons Company, the Knight Saber, and there were no other clues to help.

Soon, the saber tea party was interrupted by the appearance of a woman.

Sumiko Sato pushed open the door of the café and walked in.

Kamio Kaede glanced at the other party and felt a little unexpected.

Sumiko Sato does not have the image of a woman in the red light district as ordinary people remember, she is probably less than 30 years old, wearing a goose-yellow hip-wrapping skirt, flesh-colored stockings and high heels, long straight black hair draped over her shoulders, and a pair of rimless glasses, as if she were a female teacher on a college campus.

"The three of them should be officers from the police station, right? Sorry for keeping everyone waiting for a long time, and going out was delayed for a while. ”

Sumiko Sato recognized Kamio Kaede at a glance, walked over with a bewitching gait, bowed deeply to them, and then showed a professional signature smile.

Ao Si looked surprised and said, "There are so many people in the café, how did you recognize us?" ”

Zuoto Chengzi stroked the hair scattered around his ears and smiled: "In our industry, we will always know people's skills, although the three police officers are dressed in civilian clothes, but the temperament in their bones can not be hidden." It was a temperament with justice and bravery. ”

Okuji smiled and said that she was really good at complimenting, and then beckoned the other party to sit down and ordered a cup of coffee for her.

The four of them sat at the same table, and Kamio Kaede didn't beat around the bush, and asked straight to the point: "Kobayashi Chunshui is your roommate, right?" ”

Zuoto Sumiko nodded very calmly, "That's right, I live in the same apartment with Kobayashi Harusui and Hatsu Momoyu." And to make no secret of it, all three of us are princesses in Kabukicho, and we pay protection fees to the same boss every month. ”

When the other party mentioned his identity as a maid, his expression was calm, and there was no shame or embarrassment, as if this was a habitual thing.

"So where did Hatsu Momoyu go? Why did you all disappear after the accident with Kobayashi Harusui? Okuji asked.

Sumiko Zuoto looked at him with an idiot expression, "We are engaged in unauthorized tricks, and you are the police, knowing that the apartment is about to be searched, and you don't pack up and run away, are you waiting to be caught?" ”

"Then the death of Kobayashi Chunshui, don't you have any doubts or sorrows? It's a roommate who has lived together before, so maybe you can provide some clues to the police. Okuji said.

"It's just the connection of the meeting of Pingshui, and if you die, you will die." Zuoto Sumiko said surgingly, "In our business, there are not a few customers who have conflicts because of price, and she must have been killed by a customer who was angry and ashamed." ”

Okuji frowned slightly, not very satisfied with this woman's rash attitude, but he didn't tell her the truth about Kobayashi Harusui's death, and the details of the eucalyptus were still in the stage of secrecy.

"Where did Chu Taoyu go, the police didn't find her during this time, where are she hiding?" Okuji asked.

Zuoto Sumiko shook her head, "I ran away with Chu Taoyu after packing up my things in the apartment, and I haven't been in touch again, who knows where she went to hide, maybe she has already left Tokyo and returned to her hometown in the countryside, and our boss hasn't contacted her." ”

"A big living person suddenly can't be contacted, so you didn't inquire? Even if Chu Taoyu leaves Tokyo and returns to his hometown, he should inform the boss according to the etiquette, right? Aren't you worried if you encounter any danger or if someone takes you captive? ”
