Add a little water to the sharp edge and start scraping the knife, getting rid of the rust and following diagonal movements, alternating between each side so that both sharpen.

Finish by running the knife through wood a couple of times to get rid of excess, and finish by running the knife over the rubber of a shoe sole.

Q3: How to build a knife sharpener?

Get some wood, a miter saw, a drill and drywall screws, a jigsaw, sharpening stones, and lastly, a good knife.

Cut a base for the sharpener, the same width as your main support, i.e. the stone. This last one you can cut it with the chop saw, approximately two inches. Continue cutting a side rail of wood marking about 22 degrees on the saw. Fasten the stone bracket to the base with the drywall screws, leaving about 3 millimeters between the end of the base and the start of the bracket.

Cut two thin wooden slats and make a center hole in each one. These will hold the stone to the stand. Use a 3-inch bolt and wing nuts to make the adjustment.

Plug it in

When you have the electric knife sharpener in your hands, find a place to plug it in. Try to use an outlet that is close to a stable surface, and if that’s not possible, then it’s best to purchase a power strip or extension cord before choosing an unstable location.

turn on the device

The ignition only consists of a button. As soon as you turn it on you can hear the slight sound of the motor that indicates that the product is ready.

Rough the knife

Whether electric or manual, all modern knife sharpeners come with a grinding slot. This process repairs certain deformities that may be on the blade and gets rid of rough edges while giving the most damaged areas a bit of shape.

The sharpener may name this slot coarse, 1, or “coarse.” It all depends on the model.

have a right move

Do this two or three times, depending on the materials used for sharpening or the power of the product, if it is electric. Do not add pressure or downward force, as this could damage the knife or sharpener.

Always keep a good grip on the handle or make sure you have adhered the suction cups well to the surface, as it is dangerous for the device to slip.

Proceed to do the finishing and polishing

There are certain sharpeners that have more than one slot, but the most common ones only have the roughing and polishing slots. This is identified by the word fine, “fine” or the number 2. Here the blade will be sharpened more precisely and the excess material left on the blade at the end of the first process will be polished.

The movement you must carry is the same as the one explained in the previous step.

Rinse the leaf and dry

When you’re done sharpening, rinse the knife well to get rid of any residue and dirt. Use a clean cloth to dry everything to prevent water from sitting there for too long, wearing down the handle of the product.

Disconnect the device

Carefully unplug the sharpener for storage. If it has an automatic winding function, press the button so that the cable stays in its place.

Save it

Take it to a place where it will be kept clean and leave it there until its next use.
