Choosing The Right Mechanical Pencil

Build quality

A mechanical pencil needs to balance perfectly in your hand, and as a result be comfortable to use. A lot this is a result of its stiffness and weight, and there are many cheaper and lighter products that available that fail to provide these aspects.

Lead quality

The quality of lead is very important and sing the right type can make a big difference since it is the lead that determines how the pencil writes. When choosing lead, it is important for you to take the hardness grade into consideration.

Leads that are softer are smoother and softer compared to harder leads. Softer leads also get used up faster as they erode quicker during use.

Lead advancement quality

Push button – Mechanical pencils have different mechanisms that they use to advance the lead. The most common type of lead advancement technique is the push button mechanism. This type of lead advancement mechanism have a push button that when clicked pushes a fixed amount of lead through the nib.

Most commonly the push button is located at the top of the pencil, but some have a button built into its clip or on the side.

Shaker – Another lead advancement mechanism is the shaker technique. The shaker technique works in a way such that when the pencil is shaken, there is an internal click mechanism that is activated by a sliding internal weight, which then advances the lead.

This technique has caught on since you are able to advance the lead without changing your grip.

Twist – Thirdly, a twist mechanism. This technique allows you to make continuous adjustments to the advancement of lead through twisting and turning of an adjustment located at the top of the pencil to advance and retract the lead. This mechanism allows you to choose your preferred length of lead.

Bend/body knock – The bend or body knock mechanism is another lead advancement technique that advances the lead when a specific joint in the grip section is squeezed.

Automatic – Lastly, this method advances more lead when a ratchet mechanism is activated by the pressure of lead on paper.

Lead size

Leads come in a large variety of widths and levels of hardness that generally speaking define the purpose they are used for.

Mechanical pencils with different lead sizes are used for different purposes. The thinnest leads (0.2mm – 0.4mm) are ideal for the most compact equations requiring small spaces and for adding the finest of fine details to artwork. They are also best suited for people with small handwriting.

All-purpose leads are the most common lead size (0.5mm – 0.7mm) since they provide a wide range of styles and features. All-purpose leads are suitable for writing at most sizes and drawing details at most sketching sizes.

Thick leads (0.9mm – 1.3mm) are uncommon and are best suited for people who make bold sketches, have extra large handwriting, or press with a very heavy hand. Thick leads feel smoother compared to smaller lead sizes and they do not dig into the paper.

Eraser

Most mechanical pencils usually come with a built-in eraser. However, the erasers are often very small. In some instances, once the eraser has been completely used up, it cannot be replaced. It is therefore important to choose a model with an eraser that is replaceable if you intend to use it on regular basis.

Ergonomics

Mechanical pencils that are ergonomic have been designed to reduce fatigue and minimize the stress on your hands allowing you to use them for longer periods of time.

Lead cushioning

Lastly, lead cushioning is another very important factor to consider. Several mechanical pencils have different ways of preventing the leads from breaking. The most common way that the lead is protected from breakage is by use of a sliding leas sleeve.

The sliding sleeve protects the tip of the lead while you write. The sliding sleeve is constantly pushed back by the paper surface as the lead wears down.

Maintenance and Accessories

Maintaining your mechanical pencil is crucial to ensure its longevity and optimal performance, especially for architects who rely on precision and durability in their drafting tools.

Alongside regular maintenance, selecting the right accessories can enhance your drawing experience.

Maintenance Tips for Mechanical Pencils

  1. Regular Cleaning: Disassemble your pencil periodically to remove any lead residue or dust that accumulates inside the barrel. This prevents jamming and ensures smooth lead advancement.
  2. Proper Storage: When not in use, store your mechanical pencil with the lead retracted to avoid accidental breakage. Keeping it in a pencil case can also protect it from physical damage.
  3. Lead Replacement: Use the correct lead size specified by the manufacturer to avoid jamming. Inserting the wrong size can damage the internal clutch mechanism.
  4. Grip and Barrel Care: For pencils with metal barrels, keep them dry to prevent oxidation. For rubber grips, clean them with a damp cloth to remove oils and dirt, maintaining a comfortable grip.
  5. Avoid Dropping: Mechanical pencils, especially those with delicate tips like the Rotring 600, can be damaged if dropped. Use a wrist strap or ensure a secure grip during use.

Essential Accessories for Mechanical Pencils

  • Lead Refills: Keeping a stock of high-quality lead refills ensures you never run out. Leads come in various grades from soft (B) to hard (H), allowing architects to choose the right contrast and hardness for their drawings.
  • Erasers: While many mechanical pencils come with built-in erasers, investing in a high-quality eraser provides cleaner erasures and less damage to your drawings. Consider kneaded erasers for light erasing or plastic erasers for more precise corrections.
  • Lead Pointer: For thicker leads (e.g., 2mm used in Staedtler Mars Technico 780C), a lead pointer is essential for sharpening the lead to a fine point, ensuring precision in your drawings.
  • Pencil Case: A durable pencil case not only organizes your mechanical pencils and accessories but also protects them from damage during transport.
  • Cleaning Tools: A small brush or compressed air can be used to clean the interior parts of the pencil during maintenance.

Regular maintenance and the right accessories can significantly enhance the performance and lifespan of your mechanical pencil. For architects, these practices are not just about preserving a tool but ensuring that their creative and technical expression is never hindered by preventable issues.

By following these maintenance tips and selecting appropriate accessories, you can ensure that your mechanical pencil remains a reliable partner in your architectural endeavors.
