Different parts of a knife<br />End - The very end of the knife, which is used for piercing. <br />2. Blade - The first third of the blade (approximately), which is used for small or delicate work.<br />3. Edge - The entire cutting surface of the knife, which extends from the point to the heel.<br />4. Spine - The top, thicker portion of the blade, which adds weight and strength. <br />5. Finger guard - it provides security and comfort.<br />6. Bolster - Integral part of the blade that provides weight and perfect balance.<br />7. Handle - Gives the knife a better grip and prevents slipping.<br />8. Heel or base - it provides more control and security when holding the knife. <br />
Main componentsType of blade<br />Blade with straight edge allows a clean cut. <br />It can be used for the soft or semi hard food cut, and also to make delicate cuts, like skin or decorating.<br />End of the blade<br />The back of the blade is straight and the edge is curved. This form allows the balance of the end on the <br />cut surface.<br />Handle<br /> Water/oil resistant<br /> High quality plastic<br /> Easy to clean<br /> High durability<br /> Resistant to sudden temperature changes<br />
<ul><li> A power grip – The total inner hand surfaces grasps the </li></ul>handle which runs parallel to the knuckles and generally <br />protrudes from one or both the sides of the hand.<br /><ul><li> Support by little finger and side of the hand.
The shaft passes under the thumb.</li></ul>In many cases hand itself is supported on the work surface.<br />Grip<br />The change in the cross section of the handle reduces the forward and backward movement of the knife and permits greater force to be exerted.<br />Guard on the front of the handle permits holding the tool farther forward, which may improve accuracy.<br />It also acts as a shield against heat. <br />The guard prevents injury from the movement of the knife itself. <br />
