For some time, my preferred on-the-go pencil sharpener has been a (older) Kum brass single-holed design. Recently I wanted another (it’s so tiny you might as well put one anywhere within reach), and, as it turns out, the brass ones are hard to find in the States (possibly because of something to do with lead?); so the next best thing was the same design, by the same company, but in a lighter-weight silver-colored magnesium alloy. At the price, this is a pretty good sharpener, but I’m also gonna mentally compare it to the brass version, which I do find is the superior of the two.
The design is a super-simple “wedge” shape; a box with a slanted top where the blade is screwed in. On either side, there are ribbed divots for you to grip when using, and besides that there aren’t a lot of “features” (no shaving containment for sure). The labeling is clear and there is a little bit of “decoration,” but the whole thing is pretty bare.
Sharpening is lovely: the contraption is as small as can be but still easy to hold, everything is machined well for precise angles and the blade is sharp, cutting through all the pencils I tried with ease. The points it produces are slightly shorter than I prefer, but that is a minor consideration: they are still well pointed and easy to use. Here I should note that the sharpener is very light, and feels almost flimsily in the hand. This doesn’t affect the function in any way, and the sharpener is indeed rock solid, but at about 4½ grams when compared to the brass’ 19 grams, it just feels feathery and unpleasant in my opinion. (The edges are also much sharper when compared to the brass version, but that might have to do with wear).
If you’re looking for an inexpensive, no-frills pencil sharpener that gets the job done well, I’d look into picking one of these little guys up. They are hardy, usable, and portable. In some cases they’re cheap enough to be “disposable” (I got mine for $2, which is half what I was seeing them go for online), but they have easily replaceable blades for a guaranteed lifetime of use (though, in some cases it seems like the blades cost more than the sharpeners). And, even though I think the brass version is superior, there certainly isn’t anything wrong with the newer magnesium one.
