Then, apply a thin layer of the oil or beeswax mixture to the blade and handle, making sure to cover the entire surface. Allow the oil or wax to soak in for a few minutes, then wipe off any excess. This will help protect the knife from rust and moisture, keeping it in good condition for years to come. **

Next, place the knife blade on the piece of wood where you want to split it and gently tap the back of the knife with a baton or another piece of wood. Slowly increase the force of the strikes until the wood begins to split. Continue this process until you have split the wood to your desired size.

The SS, or Schutzstaffel, was originally a paramilitary organization within the Nazi party responsible for protecting high-ranking party officials. However, under the leadership of Heinrich Himmler, it grew to become a powerful and influential organization involved in various aspects of the Nazi regime, including running concentration camps and carrying out atrocities during the Holocaust. The Waffen-SS, on the other hand, was the armed wing of the SS and was responsible for combat operations. It was initially formed as a small armed unit to provide protection for high-ranking SS leaders, but it eventually grew into a significant military force that fought alongside the regular German army during World War II. The Waffen-SS was known for its brutal tactics and was involved in numerous war crimes and atrocities. **
