Skip-peeled logs have some but not all of the inner bark removed for a very rustic look. The inner bark, the fleshy tissue between the smooth tree trunk and the rough outer bark, is called cambium.
The tool used to strip the bark in the skip-peeling process is called a drawknife. It has a single blade with handles at both ends; the handles are pulled to draw the knife edge down the log and shave off the bark.
More intricate areas of the log need to be skip peeled by hand with a drawknife, but a machine can also remove the cambium in smoother planes of the log.
The cambium will eventually wear away or fall off without a sealer to coat and protect the finish.
When all of the inner bark is removed, the process is known as a clean peel. Top coats or waxes are then applied to give a satiny finish.
