![]() ![]() In addition to the best overall buys, test results can also be viewed in categories such as different lead advancement mechanism styled pencils and best models for professional technical drawing. The reviews look at all these elements for each pencil before listing their results, usually in order of preference, as well as listing the pros and cons they identified for each product. These are key functions of any mechanical pencil which needs reviewing and consideration before purchase. Designs and styles are of course elements of personal taste, but these reviews are meant as guides in weighing up and comparing the many different pencils and styles you can find on the market today.įactors which these tests analysed and evaluated include consistency and crispness of lines, lead sizing, lead tip advancement mechanism type, style and material used, pencil grip, eraser length and lead tip protection. In this way they can lay out their comparison tables with best buys after considering the main factors for which consumers would buy and use a mechanical pencil. Independent review sites conduct thorough examinations of market leading mechanical pencils, as well as consulting experts in the field and using their own experience with products to evaluate their overall test results. How Product Tests are Conducted and What Was Taken in to Account You can assess whether their test winners are suitable for you or you could draw up a comparison table to further best evaluate the results. Different types of jobs require different writing and drawing styles for which the size of the lead tip of a mechanical pencil is key. If possible you may want to try a mechanical pencil before buying to review if it performs how you require.Another eraser design which does not work for everyone is having them covered, so that the user needs to remove the cover every time they want to correct an issue with their work. However on some models the design and look of the mechanical pencil has trumped the practicality of the eraser, ending up with an eraser which is not full-sized and soon used up. Mechanical pencils come fitted with erasers on the end, similar to most wooden pencils. A key advantage of using a pencil is the ability to erase any errors before correcting them.Review any instructions you may have received with the pencil, but a replacement lead should never be forced in to a mechanical pencil as this can result in it becoming jammed. Check you buy the correct size lead tip refill for the pencil you have. Make sure to review the pencil you are using to make refilling the lead easier when the time comes.If the lead has broken in more than one place you may have to click a few times before a suitable length of lead is in place for the pencil to best work again. By clicking or twisting the pencil to propel more lead forward this issue should be overcome. If the lead keeps retracting back in to the pencil barrel it means the lead tip is too small, possibly because it has broken within the barrel.The pencil should be gently shaken to see if this clears it, but if it does not the pencil will need cleaning out to dislodge any lead parts trapped within the mechanism. If it is correct there may be a lead jam. First of all you will need to check the right lead size is fitted for the pencil you are using. There is a similarity here to when the lead breaks. Sometimes you may experience problems with the lead tip not extending from the pencil barrel.There are mechanical pencils offering break-resistant lead which may be best for your use, while coloured leads can be more fragile and may be best avoided. A harder lead grade may be required or possibly a wider one. The lead you are using may be too fragile for the work you are doing or for your style of writing or drawing. If you find the lead tip is breaking often while you are writing or drawing with a mechanical pencil then you need to review the type of pencil and the lead it contains.You may need to remove all the lead and use a thin gauge wire to clean out the mechanism. In this case you may need to unscrew the tip from the barrel and check for any obstruction such as lead jamming the mechanism. Sometimes this needs a good amount of clicking before any replacement lead appears, but sometimes this still does not resolve the issue. If you are fortunate you can just propel replacement lead forward from the barrel by clicking it, twisting the barrel or through whichever mechanical method your pencil uses. Similar to any pencil the lead in a mechanical pencil can break or snap, sometimes at the least opportune moment. ![]()
