Cold Steel Stylus Knife Sharpener

As a fan of this brand, as soon as I saw the YouTube video on their channel where they showed a sharpener dedicated to serrated knives, I decided to buy it. My first impression – the sharpener does not have the right surface for sharpening the thinnest serrations on Cold Steel blades. That's strange, especially since the manufacturer already had a previous model suited to this type of tooth – the Lansky LTRCS. I tested it on a Kershaw Livewire Double Edge serrated made of CPM Magnacut steel – the result was very poor. The sharpener's edges are uneven, and the abrasive layer contains much larger grains than declared, more like 120 grit than 600. While sharpening you can hear and feel the blade catching on bigger particles or bumps, and after a few attempts, the blade would not cut paper. Maybe this sharpener needs some time to break in, like some diamond plates, or maybe I received a defective unit – but after the first use, I don't intend to use it on Cold Steel knives anymore, just to avoid damaging the serrations. In this case, it's better to stick with the old ceramic Lansky LTRCS sharpener. For other serrated blades, a regular and inexpensive Taidea Pen 600 performed much better – with it I was able to easily sharpen the Kershaw Livewire and I was pleasantly surprised that such a cheap tool could be so effective.

A solid sharpener, I mainly use it for sharpening serrated edges. It fully does its job. When folded, it takes up little space, so you can always have it on hand. I definitely recommend it.
