Lump saw
The Klobsäge is a hand-held saw for dividing round logs into boards, planks or veneers .
The lump saw is one of the tensioned hand saws. It consists of a wooden frame with a saw blade of up to 150 cm in length clamped inside. The saw blade is thin to reduce the loss of cut and about 100 to 130 mm wide for better guidance in the cutting direction. It is attached to the cross braces with clamps and tensioned with a screw. Often there are handles on the lower cross strut and a grip strip on additional extension struts on the upper one. In other designs, the cross struts of the frame protrude beyond the longitudinal struts and are shaped for better grip.
The log saw was mostly operated vertically by two or more workers, with the trunk to be cut lying horizontally or at an angle on a frame or over a pit. When cutting veneer, you also worked horizontally with a vertically stretched trunk.
