- proper knife liquid degreasing knife (petrol, alcohol, cologne), the figure to be applied to the blade of a knife, tape, a sharp knife or scalpel, power supply 5 ... 12 V, nailwith a wound on her hat wool, salt solution (one teaspoon per 50 g. of water).
Drawing on the knife blade can be applied by means of electro-chemical etching.This is a simple way of labeling on all metals and alloys without the use of complex chemicals.It is based on the principle of electro-etching metal.However, this method is not suitable for silver and lead.Get to work.
Figure.Think about what the drawing is applied to the blade.You can engrave the Chinese character or the whole word.
Preparation blade.The surface of the blade it is necessary to degrease, because this directly affects the quality of the applied pattern.Degrease any available handy liquid: gasoline, alcohol or cologne.
Pre-patterning.Stick on the blade in the right place a piece of tape.Apply a sharp knife or scalpel to scotch pattern, being careful not to damage the adhesive tape.
metal etching.At this stage you will need a power supply, you can use the charger from the phone.Prepare the brine.Then proceed to the electrochemical cleaning of the metal surface.Connect the "+" to the knife, and "-" to the nail with a cotton hat, it will replace the electrode.Then turn on the power supply, dip the electrode into the saline solution and draw on the drawing surface.This procedure was repeated 2-3 times for best results.
Then change the cotton head of the nail to clean and change the polarity of the power supply "+" to the electrode, and "-" to the knife.Dip the electrode into the saline solution and begin to display the picture that will be shown on the eyes.To achieve maximum effect, repeat the procedure 2-3 times.
end of work.Peel off the adhesive tape from the knife and remove the sticky traces.Engraved on the blade of the knife is ready.
