Cold Steel Stylus Knife Sharpener

As a fan of this brand, right after watching a video on YouTube from their channel, where they showed a sharpener dedicated to knives with serrated blades, I decided to buy it. My first impression – the sharpener does not have a suitable surface for sharpening the finest serrations in Cold Steel blades. This is strange, especially since the manufacturer already had a model suited for this type of serration – the Lansky LTRCS. I tested it on a Kershaw Livewire Double Edge serrated from 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 instead of 600. While sharpening, you can hear and feel the blade catching on larger particles or bumps, and after a few passes, the blade would not cut paper. Maybe this sharpener needs some break-in time, like some diamond plates, or maybe I got a defective unit – but after the first use, I don't intend to use it on Cold Steel knives anymore, so as not to damage the serrations. In this case, it's better to stick with the old ceramic Lansky LTRCS sharpener. For other serrated blades, the regular and cheap Taidea Pen 600 worked much better – I was able to sharpen the Kershaw Livewire without any problems and was pleasantly surprised that such an inexpensive tool could be so effective.

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