How to properly used a chisel?

There are many different types of chisel available for working wood and each has been designed for a specific application. Strike the chisel with a hammer and chop down about 1/2 in. Then chisel from the end to remove the piece before continuing. Your chisel must be sharp for this cut. Set the chisel alongside one cut edge and strike it sharply with a hammer to remove wood from notches.

Is it really important to use chisels in order to cut materials?

Chisel tools are used for cutting or carving hard materials such as metal, stone or wood. A chisel tool has a shaped cutting edge of a blade on its end, with a handle that is characteristically made of wood or metal. In order to cut into a material – wood or metal – a chisel tool is forced into the material. So it is very important tools also

Cold chisels are made from carbon tool-steel, which is usually octagonal in cross-section. Tool-steel is used as it can be hardened to form a hard and tough cutting edge. To make a cold chisel heat the end of the bar of tool steel until it is bright red and hammer to the desired shape.

A cold chisel is a tool made of tempered steel used for cutting 'cold' metals, meaning that they are not used in conjunction with heating torches, forges, etc.

It is used to clear out material in corners and for cutting V-channels. While you can use a cold chisel for masonry work, it is easier to cut into stone, concrete or brick with chisels especially designed for that purpose.

Chisels were among the earliest tools. They have been employed (in their most basic form) since Stone Age man learned to break stones into a roughly flat shape with a sharp edge.

With the invention of hotter furnaces and the ability to smelt iron ore, the softer bronze chisels were, in turn, replaced by ones made from iron.

Chisel comes from the Old French cisel, modern ciseau, Late Latin cisellum, a cutting tool, from caedere, to cut.

A toothed stone chisel, used by stone sculptors and stonemasons
Stone chisels are used to carve or cut stone, bricks or concrete slabs. To cut, as opposed to carve, a brick bolster is used; this has a wide, flat blade that is tapped along the cut line to produce a groove, then hit hard in the centre to crack the stone. Sculptors use a spoon chisel, which is bent, with the bevel on both sides. To increase the force, stone chisels are often hit with club hammers, a heavier type of hammer.

There are four common types of cold chisels. These are the flat chisel, the most widely known type, which is used to cut bars and rods to reduce surfaces and to cut sheet metal that is too thick or difficult to cut with tin snips. The cross cut chisel is used for cutting grooves and slots. The blade narrows behind the cutting edge to provide clearance. The round nose chisel is used for cutting semi-circular grooves for oil ways in bearings. The diamond point chisel is used for cleaning out corners or difficult places and pulling over centre punch marks wrongly placed for drilling.

Step 1 - Prepare to Chisel
Use a ruler and carpenter’s square to carefully measure and mark both the area of the surface and the depth you want to remove. Next, clamp the wood down to your work surface to keep it from moving while you work.

Step 2 - Outline and Score the Area
For a shallow groove, hold the chisel at a 90-degree angle to the wood and use a wooden mallet to tap the blade of the chisel to the desired depth. Repeat this step all the way around the surface line you marked in step one. Inside the marked area, make parallel cuts 1/4 to 1/2 inch apart, to the same depth as the outline, across the grain of the wood.

Step 3 - Chisel the Groove
Hold the chisel with the beveled side toward the wood. Run the chisel in the direction of the wood grain but away from your body. Chip out the scored area until you have removed all the wood inside the outline to the desired depth.

Step 4 - Refine the Groove
Depending on your project requirements, you may need to refine the groove. If you are working right to the edge of the wood on at least one side, hold the chisel so the flat side is flush with the wood. Run the chisel along the area to smooth the surface and finish with sandpaper, if desired.

wood chisel
Make sure that the cutting edge is sharp. Dull chisels can be difficult to control and require more effort to do the job.
Check the stock (wood) thoroughly for knots, staples, nails, screws or other foreign objects before chiseling.
Clamp stock so it cannot move.
Adjust your stance so that you do not lose your balance if the tool slips.
Chip or cut with the blade pointing away from yourself.
Keep your hands and body behind the cutting edge.
Use a wooden or plastic mallet with a large striking face on all chisels. Only heavy-duty or framing chisels are made of a solid or molded handle that can be struck with a steel hammer.
Make finishing or paring cuts with hand pressure alone.
When keeping the chisels on the work bench, always place them with the bevel side up.
Place chisels safely within the plastic protective caps to cover cutting edges when not in use.
Replace any chisel that is bent or shows dents, cracks, chips, or excessive wear.
Store chisels in a "storage roll," a cloth or plastic bag with slots for each chisel, and keep them in a drawer or tray.
Replace broken or splintered handles.
Sharpen cutting edges as often as necessary.
Wear eye protection if there is a risk of eye injury from particles released from the workpiece or when sharpening.
