tverrsakse

Tverrsakse is a term used in Norwegian for a crosscut saw, a hand tool designed to cut wood across the grain. In carpentry and logging, tverrsakse are used to shorten timbers, cut boards to length, or buck felled logs. They come in two main configurations: two-man saws with handles at each end and single-man saws with a front handle. The blade is relatively thick and stiff, with teeth arranged for cross-cutting rather than ripping. Crosscut teeth are pointed and set to bite across fibers; many designs include a raker tooth after several cutting teeth to clear sawdust and reduce binding.

Length varies by use, commonly in the range of 60 to 120 centimeters, with handles sized accordingly. The blade is usually made of high-carbon or alloy steel and can be sharpened with a triangular file. Tooth count per inch (TPI) commonly ranges from around 6 to 12, with a raker tooth pattern on traditional saws to maintain a clean kerf.

In use, the saw is guided along the cut line; two-man versions are operated by both workers pulling and pushing, while single-man varieties rely on a forward stroke. Proper support of the workpiece and a stable stance reduce binding and kickback.

Historically, crosscut saws have a long history in European woodworking and forestry, and remain in use among hand-tool enthusiasts and certain traditional trades. Maintenance includes keeping teeth sharp and evenly set, cleaning, and oiling the blade to prevent rust.
