Build Quality
Overall Design Scoring

The Smith’s Pull Thru sharpener is made with decent materials and enjoys a nice fit and finish. Unfortunately, it suffers from poor design, in particular an elevated working section and a long and narrow base.

Despite its affordable price, the Muller 4-stage sharpener has a strong, solid build, substantial abrasives, and tightly-fitting parts. It has a nice fit and finish and a spacious grip that’s comfortable to the touch. However, a lower working section would offer better control and stability.

Overall Usability Scoring

On the whole, the Smith’s Pull-Thru was one of the most versatile and convenient handheld sharpeners we’d experimented with so far. However, it was due to two major flaws that some points were docked away: the odd sharpening order and the feeling of unsteadiness.

Though the Mueller is a bit tall, it offers decent balance and stability. Its large size and substantial abrasives give you a lot of confidence when sharpening. The slot layout could be improved, in our opinion, but it doesn’t pose much of a problem in terms of usability.

Overall Performance Scoring

The Smith’s Pull-Thru pulled off good grades when it came to sharpening time and maximal keenness. However, it failed to replicate the same success for other aspects.

It won’t make your knife razor-sharp, but the Mueller takes little time getting a dull edge ready for common cutting tasks in the kitchen. Contrary to its twin, the Longzon, however, it eats away the blade and leaves a rough, uneven edge.

The Mueller isn’t a perfect manual sharpener, but it certainly has an edge over the Smith’s 50264.

Both devices are fast and effective, with the Mueller leading the speed test by about 10 seconds. The Mueller was also more forgiving of the knife’s edge, though admittedly only because the Smith’s was the most detrimental of all the pull-through devices we’ve tested to date, scoring low in both material retention and edge smoothness.

The Smith’s is more versatile in terms of edge angle. However, this is also where its Achilles’ heel lies: It sacrifices sturdiness for adjustability. The sharpener also sports a very narrow base, which further limits its ability to stay firm and balanced during sharpening.

The Mueller does suffer from a working section that’s placed a bit too far above its base, but its base size was enough to ensure decent stability. Overall, it’s the safer and easier sharpener to work with.
