Video: How To Sharpen Tools Correctly

As a rule, axes are on sale with a straight blade. Working with such an ax is hard and unproductive. This is because a straight blade enters the wood across its full width, and it takes a lot of force to work with such a tool. With a rounded blade, the ax works like a scherhebel - the blade breaks down the separated wood chips. The radius of curvature should be about 250-270mm, the angle of curvature for a carpenter's ax should be approximately 350.
When placing an ax on the ax, the following should be borne in mind: the free end of the ax must be in the plane passing through the ax blade. Otherwise, the accuracy of the hits will decrease. When wedging the handle, care must be taken that the end of the handle does not leave the indicated plane.
Particles of the processed metal will not get stuck in the cut of the file if the file is previously rubbed with chalk or charcoal.
Knives, chisels and other cutting tools sharpen easier and faster if you first immerse the blade for half an hour in a weak solution of sodium chloride, and slightly moisten the bar with kerosene.
A used vibration-powered electric shaver can be turned into a sander. To do this, you need to remove the knives and replace them with a piece of rubber sheet, to one side of which glue a metal plate with holes for vibrating levers, and to the other sanding paper or cloth, on which you can apply sanding paste.
Various combinations of broken blades from a hacksaw for metal will help to make the cuts of the desired width. The fact is that the divorce on them is not made according to individual teeth, but along the working edge of the blade itself, so that a wavy edge is formed. By putting together several fragments, it is possible, due to their mutual displacement, to change the width of the cut: the "waves" on the edges coincide (without displacement) - the width is the smallest, they will not coincide (one against the other) - the largest. You can fasten pieces of canvases with small clamps to a solid canvas.
Saw with poorly set teeth gets stuck in wet wood. It is enough to smear the canvas with soap, as the work will go faster.
It is easy to clean the saw from sticky pine resin with kerosene, and when cutting deciduous logs, sticking can be avoided by adding water to the cut. Sometimes, due to the small diameter, the drill cannot be clamped in the drill chuck. Wrap copper wire on a nail or drill of a smaller diameter - tightly, turn to turn, clockwise. Now put the resulting spiral on the shank of the desired drill: when clamping and working, the spiral will jam and hold securely in the chuck.
A beer cork nailed to the butt of the chisel handle will reliably insure the handle against the possibility of splitting when hit with a hammer.
The handles of the hand tools can be covered with PVC tube. To make the tube swell, it is immersed in acetone for 15 minutes. After that, it can be easily put on the handles, and when dry, tightly wraps around them.
There is one secret to know when sharpening scissors. Usually scissors are sharpened with a fine-grained bar, then guided with a razor wheel - the blades are very sharp. And scissors don't cut. What's the matter? It turns out that the smooth, polished blades slide, pushing the material out, making it particularly difficult to cut hair. You need to sharpen the scissors with a coarse-grained bar, passing them along the blade from end to axis at an angle. The smallest oblique teeth formed on the sting will prevent the blade from slipping.
