Where and when was the first chisel used?

(Do’s)
1) “Work” end of chisel should be uniform in shape.
2) Chisel “shank” should be uniform in shape and material
consistency.
3) Chisel base and retention collar (inside power tool) should
be uniform in shape and material consistency.
4) If redressing is required, dip the dressed end of the chisel
into water during the redress process. Keep chisel tip cool or
you risk the chisel’s hardness integrity.
(Don’ts)
1. Do not pry with any chisel.
2. Do not use chisels that show excessive wear, dents, chips,
mushrooming, or improper dressing.
3. Do not use chisels that have a misshapen retention collar
(no egg shapes).
4. Do not use worn chisels. These chisels can release
chips/particles into the power tool that can become lodged
inside the barrel, effectively jamming the piston inside the
tool.
5. If redressing, discard chisel if colors appear during the
redress process; i.e. blue, yellow, red, etc. This means that
the chisel has lost its uniform hardness and has just become
a safety hazard!

It depends on your work, It will be easier for you if you use a chisel applicable to your work

When it comes to business, one of the most crucial aspects to be taken care of is the company's important data or information. Every business organization will have some standard set of files or documents that contain procedures for its entire operation.

Wear safety glasses, or goggles, or a face shield (with safety glasses or goggles).
Use the right size of chisel for the job.
Choose smooth, rectangular handles that have no sharp edges and are attached firmly to the chisel.

Eventhough chisels aren’t powered by motors and belts, they are sharp and can easily cause injury. The following is a list of safety precautions to consider when using a chisel:

1. The number one rule of chisel safety is to keep them sharp. A dull chisel is a dangerous chisel, as it will require more effort to push the chisel through the stock.

2. Always clamp the work securely in a vise or to the benchtop.

3. Never hold the work with one hand while chiseling with the other.

4. Always cut with the blade pointing away from your body and keep your hands behind the cutting edge.

5. Use sandpaper to break the sharp machined edges on new chisels to prevent cutting yourself while holding the chisel.
