Zhan Xiaogui was determined to go this time and prepare to unload the gate of Liu Kui's original base. Then find a way to make the scabbard of the Ice Greatsword, which is more convenient.

Fortunately, Zhan Xiaogui and his son cooperated very well, and the two giants finally did not let the name of the giant be dusted. The father and son finally took down the big iron gate of Liu Kui's base and laid it flat on the ground.

Wang Yueyue looked at Zhan Xiaogui and his son with a little surprise: "How do you cut it now?" ”

"Huh?" Zhan Xiaogui couldn't help but be surprised when he heard Wang Yueyue say this: "How do you know? Don't you just ask if you want to use a saw or a foggy knife? ”

"Hey! Don't talk so much nonsense! Place your Ice Greatsword flat on this big iron door, I'm going to use the King Kong Incorruptible Saw to draw a mark on this greatsword and then sharpen it into the shape of the sword, and finally fuse them together! I," Wang Yueyue said to Zhan Xiaogui.

Zhan Xiaogui squared the giant sword without saying a word, and was taken down by the two of them, and it was also placed flat on the big iron door on the ground, and after it was over, he breathed a long sigh of relief and spread out his hands and said to Wang Yueyue: "Let's start!" Take out your King Kong and cut down on this saw! ”

"Don't rush it yet! You have to think about it, calculate what to do with this sheath! If it doesn't fit, the greatsword won't fit in or it won't be pulled out! Wang Yueyue said.

"Hmmm! You have to think about it! But I think you'll have to use your super advanced brain! Let's search how we humans made all kinds of scabbards before the end of the world, let's learn from it, and then have a comparison! Only with relatively adequate preparation can you make a very suitable sword cover suitable for the Ice Greatsword! Zhan Xiaogui said.

When Wang Yueyue heard Zhan Xiaogui say this, he reminded himself that he had to look for information carefully so as not to make jokes.

"Hmmm! Then don't grind to us to popularize science, search for information, and let's discuss together! Zhan Xiaogui said.

Wang Yueyue nodded, searched for information about the scabbard in his brain, and quickly summarized the knowledge points he searched, and then transmitted them to Zhan Xiaogui and Zhan Xiaogui's son through brain waves.

"The scabbard, the container used to carry the knife. The scabbard is to the knife, just like the clothes are to people, which not only satisfies the most basic protective role, but also enhances the taste and temperament. ”

"Classification of scabbards: Common scabbards include skin sheaths, K sheaths, wooden sheaths, tactical nylon sheaths, etc.

Leather sheath: The skin sheath is the favorite of hunting knives and the most common scabbard.

Compared with other wood sheaths, K sheaths, etc., the biggest advantage of skin sheath is strong toughness, compression resistance, and bending resistance. For example, in the north in winter, the skin sheath will also maintain considerable elasticity and toughness.

In addition to this advantage, the leather sheath can also be made very beautifully, with style, and is also very suitable for craft knives, and has a high collection value. But there is one thing, the skin sheath needs to be maintained frequently

K sheath: The most prominent advantage of K sheath is that it is light and durable, and that it is pressure-resistant, wear-resistant, corrosion-resistant, and waterproof. Third, it is simple to make. There are three main drawbacks. First, the elasticity is poor, it is easy to harden and become brittle in cold weather, and in extreme cases, it will even freeze with the blade. The second is rigid, if the sheath is made tighter, it is not very fast when the knife is out and into the knife, and some poor K sheaths not only can not protect the knife body, but will sharpen the knife body or coating. Third, the colors and styles are slightly monotonous. The K sheath is mostly used on small straight knives.

Wooden sheath: found in traditional Japanese knives. One advantage is that the style is quaint. Second, it can protect the blade well, even if the sand and stone enter the sheath, it will leak out of the opening at the bottom of the sheath and will not wear the blade. One of the disadvantages is that the sturdiness is poor and the fear of falling. Second, the corrosion resistance is poor, and it is afraid of corrosive liquids such as vinegar and fruit juice. Third, it is not easy to maintain, afraid of dryness and moisture. Fourth, the carrying method is slightly monotonous, mostly hanging vertically on the waist. It is mostly used for medium and large straight knives.

Nylon tactical scabbard: is a favorite of military knives, gives a cool feel, and is more commonly found on tactical knives. Nylon fiber material, one is light and durable; second, good elasticity and wear resistance; The third is the diversification of carrying methods.

The disadvantage is that it is eye-catching, and the second is that if it is not used by the military, the structure is slightly cumbersome and procrastinating; The third is very easy to get dirty. This scabbard is suitable for tactical knives.

Precautions for scabbard maintenance: At all times, pay attention to keeping the sheath relatively clean, avoid entering fine sand or liquid, and prevent abrasion of the knife.

Do not expose the scabbard to the sun or place it in a humid environment, and maintain it regularly. When exiting and inserting the knife, it should be light and steady to avoid scratching the sheath or sheath. ”

"The actual function of the white sheath is to preserve the blade, and it has no real use value (that is, it cannot be chopped, only appreciated), so it is slightly different from the knife sheath in terms of material selection and practice.

There is a kind of knife sheath called "solid wood sheath", that is, the scabbard is made of hardwood, and in order to prevent the hardwood from scratching the blade, another "sub-sheath" is set inside the sheath, that is, "into the sheath".

From the perspective of protecting the blade, the wood is moderately soft and hard, the processing performance is good, it is suitable for carving, it is not easy to deform, and it has good air permeability. The grain of the wood is uniform and delicate, with irregular Jungwood grain, the color is gray-white or light brown, and the oil content is not high. The cut wood must be dried before it can be used.

Choose the right size of wood (length, thickness, quality, etc.). Sawn the wood from the middle. Be careful not to offset the centerline when sawing, and place a mirror on the opposite side for easy observation.

Place the blade on the cut wood, mark the position of the blade, and draw a line diagram of the entire blade.

Dig out a suitable groove with a planer knife where the line is drawn. This position is very important, this groove is made to allow the blade to have a margin in the sheath, and secondly, to allow dirt to be stored on the wall of the sheath, and to facilitate air circulation in the sheath.

Handle, seam. Because the white sheath is the "pajama" of the sword, it protects the sword, so it is also particular when using adhesives. Chemical glue should not be used, because chemicals have a corrosive effect on the sword, such as residue in the sheath is a great threat to the sword.

In addition, the current chemical adhesive is too strong, it is not easy to open from the original seam, and if the dirt enters the sheath, it cannot be cleaned, and it can only be redone. The glue made by the Japanese with glutinous rice can just make up for the defects of the chemical glue above. (I currently use the substitute "water glue")

First planed out a general shape of the desired (the cross-section of the white sheath is divided into oval, smooth oval, rounded ridge octahedral, chamfered octahedral and acute ridge octahedral shape), and then trimmed with a small planer.

To make "Hatome", this time using black horns. The role of the dove is to prevent the wood around the hole from cracking and expanding, as for the material, it is actually the same as the nail, there are bamboo, horns and teeth, and the dove is the same, but it is a matter of grade.

This link is more difficult, digging a little more or less will affect the appearance of the dove after installation, especially the square dove. After the dove is done, trim the closing surface of the sheath and the handle smoothly.

Sheath grinding - a natural plant is used to grind. At this point, a complete (white sheath) was made, and the work lasted 5 days. Precautions for making white sheaths - the planing surface is smooth, the lines are smooth, the left and right sides are symmetrical, the seam is tight, and the most important thing is that the sliding fit of the sheath must be consistent, so that the blade will not shake in the sheath.

Before closing, check whether the sheath is smooth and whether the blade enters and exits smoothly. Note: The shape of the white sheath must be consistent with the blade (arc). It is forbidden to use sandpaper and abrasive cloth during the grinding process to avoid irreversible consequences caused by sand dropping. ”

"These materials are the methods and techniques used to make wooden scabbards! You have to know that the door of Liu Kui's base is made of fine iron, so I think it's better to find some ways to make metal scabbards! Zhan Xiaogui finished reading the information Wang Yueyue gave him and said.
