Abstract: A fishhook-extracting device mainly includes an elongated shank, a front end of which is a tapered spiral portion being coated with a layer of rubber skin and having a ball-shaped tip, and a rear end of which is connected to a preferably elliptic flat member. The flat member is provided along a lateral side with a notch for a fish line to pass there and be held in place, and at a front side with a U-shaped recess forming a sharp blade for cutting a fish line. When using the device to extract a fishhook from a caught fish, first move the shank for the spiral portion to tangles with the fish line to which the fishhook is connected, then push the shank along the fish line into the fish's mouth to allow the spiral portion to catch the fishhook. Thereafter, the shank is slightly pushed further to back the fishhook a little, so that the fishhook is disengaged from the fish and can therefore be easily extracted without badly hurting the fish.
