How to sharpen your planing knives

Planing knives can be of several types: sharpenable knives with a single cutting edge, knives with two cutting edges, where sharpening is not recommended, and removable inserts with 4 cutting edges. The latter are “pills” that are mounted on a helical shaft, their advantage being that they can be changed individually, thus reducing the cost.

Today we're talking about single-edged knives and how to sharpen them.

Keeping your planing knives sharp and ready for the planing operation is important for your projects. Knives with a cutting edge are made up of two parts: the beveled, angled part and the flat part of the knife, or the back of it.

For the best results, these two parts need to be smooth enough to intersect. The flatter and smoother they are, the sharper the knife will be. Now, let's take a look at how to sharpen these planer knives.

Did not understand

• Disconnect the machine from the power source.

• Even if they are old and used, knives can still cut you. Be careful how you handle them, unpleasant accidents can happen

• Check that you have correctly secured the blades. Carefully read the instructions provided with the sharpening tool to ensure that you have correctly secured the blades in the intended slot. Check again after you have set everything up.

The equipment used for sharpening abricht knives can vary from manual equipment to automatic equipment.

Let's dissect the above statement a little.

Manually operated abricht knife sharpening machines are equipped with an abrasive stone and a sliding carriage on which we fix the knife to be sharpened. In the case of automatic ones, the principle is the same, only the sliding carriage is automatically operated.

Because physics also works when sharpening planer knives, a machine equipped with a knife cooling system ensures high efficiency in the sharpening process, avoiding knife dulling, which ensures a longer lifespan.

Sharpening planing knives can be a necessity in workshops where the workflow is constant, and the need for tools that perform quality activities is very important. 

Our recommendation is to purchase a dedicated sharpening machine, because the cost at which the sharpening operation can be performed decreases dramatically. Even if the initial investment in the sharpening machine seems high, over time the benefits will be seen. In a field like woodworking, where costs must be weighed and time capitalized, it is important that any operation we undertake is fast and financially efficient. The expected time in the case of sharpening by a specialized company and the cost of this operation, make us believe that independence from them is the preferable thing.

So, choose to be independent!
