Alvin Draft/matic 0.3 mm
Let's start this review with a look into the history of the Draft/matic. The Alvin Draft/matic is based the Koh I Noor Rapidomatic, which already has several features that are similar to the rOtring 600: the knurled grip, the metal clip, the lead hardness indicator, and the minimalist style design. The main differences are that the rOtring 600 has a hexagonal upper barrel and a full metal body as opposed to the cylindrical barrel and plastic upper body of the Draft/matic. And with that, let's get into the review.
The Alvin Draft/matic is a fantastic pencil and can easily go against the rOtring 600 with comparisons. The clutch is metal, has a good 10-click test, and has a solid clicking noise when used. It has 3 features aside from the 4 mm tip: a metal clip, a lead hardness indicator, and, most importantly, a knurled grip. Each feature does what it is meant to do. The metal clip is, of course, strong and the lead hardness indicator is secure and allows selection of a lead grade without any trouble whatsoever. The knurled grip is special though because it is so sharp that cannot possibly slip the pencil from his or her hands. A majority of pencils have knurled grips that are too slippery (perhaps due to consumer appeal), thus creating the opposite on what they are meant for: a grip that relies on friction. Lastly, the construction I would consider great due to the metal grip area, the durable plastic, and the balanced center of gravity. Let's see the grading scale on this then.
Overall thought: The Alvin Draft/Matic is a fantastic drafting pencil for professionals and those who want to have a higher quality mechanical pencil without sacrificing too much money. I would just be careful not to bend the tip (as for most drafting pencils out there).
Would this make my personal list? As of August 23rd of 2017, this is the top pencil on that list.
The 0.3 mm version is the yellow one.
