7. The shaft passes under the thumb.In many cases hand itself is supported on the work surface. Grip 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. Guard on the front of the handle permits holding the tool farther forward, which may improve accuracy. It also acts as a shield against heat. The guard prevents injury from the movement of the knife itself.
