Abstract
A seam ripper includes a metal blade member, a handle and a slider. The blade member is supported by the handle and made of a shaft and a blade part at an end of the shaft. The slider causes the blade member to move between a retracted position and an advanced position. The shaft is housed in the handle at the retracted position. The blade part and at least a portion of the shaft are outside the handle at the advanced position. The blade part includes a cutting blade flanked by a needle portion and a ball-shaped portion. When the blade member is at the retracted position, the entirety of the needle portion is housed in the handle, and a portion of the cutting blade is exposed to the outside of the handle.
