True connoisseurs of knives are able to distinguish externally absolutely identical knives by the smallest details. But what about those who are not versed in knives at such a professional level? Here's a fun way to make your knife stand out from the crowd. So how do you make a drawing on a knife?
It is necessary
the knife itself, liquid for degreasing the surface of the knife (gasoline, alcohol, cologne), drawing for applying to the knife blade, scotch tape, sharp knife or scalpel, power supply for 5 … 12 volts, a nail with cotton wool wound on a hat, salt solution (one tea spoon for 50 grams of water)
Instructions
Step 1
The pattern on the knife blade can be applied using electro-chemical engraving. It is an uncomplicated way to label all metals and alloys without the use of complex chemicals. It is based on the principle of electromechanical metal etching. However, this method is not suitable for silver and lead. Get to work.
Step 2
Picture. Think about what pattern will be applied to the knife blade. You can engrave a Chinese character or a whole word.
Step 3
Blade preparation. The surface of the blade must be degreased, because the quality of the applied pattern directly depends on this. Degrease the surface with any liquid on hand: gasoline, alcohol, or cologne.
Step 4
Preliminary drawing. Place a piece of tape on the blade where you want it. Use a sharp knife or scalpel to apply the pattern to the tape, being careful not to damage the tape.
Step 5
Metal pickling. At this stage, you will need a power supply, you can use a charger from a mobile phone. Prepare saline solution. Then proceed to electrochemical cleaning of the metal surface. Attach "+" to the knife and "-" to the cotton-headed nail, it will replace the electrode. After that, turn on the power supply, dip the electrode in saline solution and slide it over the surface of the pattern. Repeat this procedure 2-3 times for best results.
Step 6
Then change the cotton head of the nail to a clean one and change the polarity of the power supply: "+" to the electrode, and "-" to the knife. Dip the electrode in saline and start drawing a pattern that will appear before your eyes. To achieve the greatest effect, repeat the procedure 2-3 times.
Step 7
End of work. Peel off the tape from the knife and remove any sticky marks. The engraving on the knife blade is ready.
