剪刀是切割工具,我們中的許多人re familiar with. As a child, you’ve used a pair of scissors to cut paper. And when you grew up, you had your hair cut with scissors or used a pair of scissors to cut something in the kitchen.
Scissors can be defined or described as hand-operated cutting instruments. It’s believed that the first scissors existed in the Middle East around 4,000 years ago, meaning the instrument first appeared on the face of the planet about 2000 B.C. Through the years, the scissors have gone through numerous changes and variations in design, but one thing has remained: their ability to cut through different kinds of materials.

Brief History of Scissors
一些人認為，著名的意大利藝術家達芬奇發明了剪刀。然而，這種切割工具比著名的傳說要古老得多。早期美索不達米亞文明被認為使用了最早的剪刀，由兩個青銅刀片組成。這些葉片末端由一條彎曲的薄銅帶連接。當銅帶被擠壓時，它會使兩個刀片結合在一起。要打開兩個刀片，用戶隻需鬆開刀片即可。
The ancient Romans are believed to have invented the design for what the modern-day scissors would look like. Their scissors looked like shears and could be relied upon to create neat and clean haircuts. The Roman scissors had iron or bronze blades connected at a middle point and between the tips and handles. Scissors of similar designs were also found in China and Korea, suggesting that these tools were traded as far east.
但我們今天所知道的現代旋轉剪刀最初是由一個名叫羅伯特·辛奇克利夫的英國人製造的。硬化和拋光鑄鋼，他製作了一把剪刀，重量輕，耐用，效率高。到19世紀初，剪刀是手工鍛造的。這些工具還具有精心設計或裝飾，可以切割頭發、刺繡、紙張和雪茄等多種材料。
剪刀的零件
我們經常認為，一把剪刀這樣的日常工具或物品的結構很簡單，隻有幾個部分。但是當我們告訴你剪刀有很多複雜的部件時，你會感到驚訝。
例如，剪頭發的剪刀對不同部位有特定的術語。
Points or Tips
刀片的末端稱為尖端。
Finger Bows
The handles are called finger bows. This is where the user inserts his or her fingers. There are two types of finger bows– one is for the thumb, and one is for the other fingers like the forefinger and middle finger.
Blades
刀片也有不同的部分。
Backside
它的外部稱為刀刃的背麵或鈍邊。
Edge
刀刃的鋒利部分叫做刀刃。拇指刀片是連接到拇指指弓的刀片，而手指刀片是連接到其他手指指弓的刀片。
回到邊緣，它也有不同的類型。鋸齒刃剪刀是初學者的理想選擇，因為刃口滑動較少。這讓用戶（在本例中是理發師或美發師）在剪幹頭發時有更多的控製權。帶有直刃刀片的剪刀最好用於使用某些理發技術，如點剪和切片。還有以鋒利著稱的帶有凸邊刀片的剪刀，因此最適合平滑切割和稀疏頭發。這通常由專業美發師保留或使用。
調整螺釘
理發師剪刀的另一個重要部分是調節螺絲。它把手柄和刀片連接在中間。調整螺釘可以是可調的，也可以是不可調的。顧名思義，一個可調的調整螺釘允許用戶改變切割的張力。另一方麵，不可調節的螺釘僅連接手柄和刀片。同時，螺孔是螺釘連接到葉片上的部分。
Bumper or Stopper
剪刀的其他部分值得一提。保險杠或止動塊是放置在手指弓之間的墊子。
Finger Rest
同時，指托是一塊金屬，用作手指支撐。它可以緩解手腕和肩膀上的壓力。它可以是可移動的，也可以是不可移動的。
Shank
The shank connects the finger bows to the blades.
翼
同時，翼子板是剪刀的一部分，夾在刀柄和調整螺釘之間。
Outside Ring and Inside Ring
The outer part of the finger bow is called the outside ring, while the inner part is called the inside ring.
Ring Flat
The surface of the finger bow is called the ring flat.
共同的
兩個葉片相交的部分稱為接頭。
有些剪刀還有一個標識，標明剪刀製造商的名稱、型號、使用的鋼材和尺寸。說到尺寸，這與剪刀的總長度有關。它是從手指弓的點到邊緣測量的。剪刀的大小因測量單位而異，這可由剪刀的製造國決定。
