Skewer
The cutting spike is a mining tool that was previously used in mining for manual cutting work . The cutting spit was used together with the cutting iron . It was used instead of the cutlery iron.
Structure and application
The skewer consists of a straight iron rod made of square profile iron. The rod has a thickness of 20 to 25 millimeters. The skewer is between 0.78 and 1.6 meters long. The skewer is therefore longer and thicker than the cutlery iron used for cutting. In addition to the iron skewers, wooden skewers were also used. At one of the ends of the skewer is a hardened steel point. In the case of iron skewers, the iron rod is shaped at one end into a slightly curved point. The tip is shaped like an arrowhead. The skewer is used in manual cutting work to clean out the corners. The skewer is used in particular where the cutting iron cannot be used due to a lack of space. To do this, it is either pushed into the corners or struck into the corners with a mallet.
