Sharpen an ax or a hatchet properly

The sharpness of the blade is crucial in a splitting tool. Not the effort is affected, but the safe handling supported. A blunt edge or incorrectly shaped blade after sharpening increases the risk of slipping enormously. When grinding, the starting shape must always be taken into account.

Required aids and tools

At first glance, properly sharpening the blade of an ax or an ax appears as a self-explanatory task. However, there are a few tricks that ensure a proper result. As a tool for self-sharpening or sharpening are needed:

  • Fine file
  • Grindstone from 240 grit or
  • Belt sander
  • water
  • strop
  • safety goggles
  • If necessary, clamping device such as vise

Predetermined blade cuts

There are basically two types of cuts. The convex cut has a "bulbous" flank profile towards the cutting edge and is mainly found in felled and split axes. A knife sharpening is shaped like an isosceles triangle. The flanks or cheeks run linearly towards the cutting edge. This form is found especially in small axes and hatchets.

The bend of the cutting edge can be straight or curved. Straight-cut blades are common in hatchets for finer work such as carpentry. Forestry and slotted axes usually have a symmetrically curved cutting edge. When editing by filing or grinding both the straight and the curved course in angle and rounding may not be changed. Asymmetrical shapes lead to dangerous slipping and uncontrollable trajectories of the splitter.

Steel and warming

When grinding steel, from which ax heads and heads are made, there is always heat. Too fast heating and cooling times can affect the internal structure and stability of the steel. During the grinding process, attention should always be paid to "gentle" transitions.

If a rotating grindstone or a belt grinder is used, cooling with water or grinding oil is recommended. For longer grinding cycles, cooling breaks should be used. Prevention of preheating the ax or hatchet, for example, in a bath with boiling water in addition to the steel preservation contribute.

Uniform procedure

Changes in the symmetry of the cutting edge must be avoided when sharpening by a very uniform procedure. The cutting edges must hit the angle corresponding to the rough grinding with the same time intervals as possible on the abrasives. This applies to both the cutting out of notches and the finishing touches.

Between grinding operations, the sanding dust should be removed, for example with the peel-off leather. When the finishing touch is finished, the blade of the ax or ax should be able to cut a piece of cardboard as it passes along it. The burrs are removed with the peel-off leather.

Tips & Tricks

To help ensure that your procedure is consistent, you can use a felt-tip pen or marker to paint the edge on both sides of a strip about two centimeters wide. The disappearance of the coloring shows you where you have already sanded.
