Our friends at Jet Pens sent this in the early summer, and it somehow got left in the “drafts” folder. Summer vacation is officially over as of this morning, and it’s time to finally finish this review of the KUM Special Diameter Sharpener.
I was confused, at first, by the graphics on this sharpener. They show two triangular and two octagonal pencils, each of two sizes. With the triangular being first and the word “special,” my Summer Brain thought it meant that this sharpener was for differently shaped pencils. But the name clearly denotes differently sized pencils, and the innards support this — as does Common Sense and basic reading comprehension. The innards are simply a double-holed KUM wedge. This is not at all disappointing to me, since this is generally one of my go-to sharpeners, especially for Fat Pencils.
This sharpener is a covered wedge, with a mechanism of sorts which can slide over the holes, to prevent shavings and graphite dust from escaping. Here it is, unassembled.
What you get is a very portable container sharpener that can sharpen nearly everything you’re likely to have on your person or in your bag or on your desk. In theory, I love it. But I thought I’d throw two sizes of a pencil which is…not as easy to sharpen as, say, a Ticonderoga — the obvious choice for differently-sized pencils of the same type. This is the Faber-Castell Grip 2001 and the Jumbo Grip. The former is certainly not cedar, but the latter is. However, being Fat and Triangular, it is not an easy pencil to sharpen in a blade sharpener.
The sharpener itself did a great job, producing a semi-short point. However, as you can see below, the black plastic body of the case marred the finish on my Jumbo Grip. This is likely at least partly User Error; I basically stuck the pencil in and twisted it violently (as you can see, perhaps). But I am pleased with the point that the KUM wedge puts on Fat Pencils, for a nice, Stubby point. I usually keep my Fat Pencils a little more…blunt, but I wanted to see what this sharpener could produce.
For the price (a little over $3), this is a great container sharpener. You might be able to see that I have scratched the clear plastic up, carrying it around a lot in my Diaper Bag and pocket. There are a few similar sharpeners from KUM floating around HQ. But they are not mine and not as “grown-up” looking as this little guy. Of course, you might ask how grown-up a man can look, using Fat Pencils. Certainly.
