Smith's CCKS 2-Step Knife Sharpener - Yellow - 2-Step Preset Coarse & Fine Slots - Outdoor Handheld Knife Sharpener - Fishing, Hunting, Fillet, Pocket Knives - Compact Plastic Portable Keychain Tool

I own several of these, so that already tells you what I really think about them.They are inexpensive, portable and easy to use.They handle curved blades easily, even a reverse curve blade which is challenging to sharpen with a stone.This is not meant to be a replacement for a sophisticated sharpening system, but it's quick, requires no setup or waiting for stones to absorb water and does the job well enough.I use it for kitchen knives, as a quick touch up of the edge, using the ceramic side, and also for outdoors knives. Again, I use the ceramic side mostly, as I don't wait for the edge to get too blunt before sharpening.The carbide side works well on very dulled edges, but all carbide sharpeners remove a good amount of steel from the knife edge, so I try to use sparingly.Cons:A few minor limitations that I am willing to live with include:- Because of the compact size (which is a plus, in my mind) the handle is small and you can only use 2 fingers to hold it in place.- Edge angle is fixed and cannot be changed or effectively controlled.- The ceramic rods are hard to reach for cleaning purposes, so they do accumulate steel residue from the knife edge. I am not sure how much of a problem this is in reducing the effectiveness of the sharpener over time. I will try some other methods of cleaning them and I'll update this review.Overall, it does what it's designed to do with no fuss and meets my everyday needs quite well especially in a portable situation.For me, it's also one tool among several that I use, depending on what I want to achieve.I have other, more sophisticated (and much larger, heavier and/or more delicate/breakable) sharpeners, if I want to spend more time and give that "special" blade more attention or if I just want to control edge angle.

Best compact knife sharpener I've ever used. So good, I've bragged about it and given it as a gift. If the most dangerous knife is a dull knife, this sharpener is the solution. One side preps the blade, and the other side quickly hones it to razor sharpness. It makes any knife better. Plus, it's very lightweight and compact for campers, fishermen, and hikers.

I used this to repair an old Frontier stockman that had its edges mangled years ago by an attempted bench grinder sharpening. The carbide side set pretty good edges on the carbon steel blades after just 10 passes, and I got surprisingly sharp, paper-slicing finishes with the ceramic side, using about 30 strokes with moderate pressure.However, there's a bit of issue with the plastic case on either side of the sharpeners. It protrudes out too far, so I couldn't sharpen about 5 millimeters of edge on the pivot side of the blades. The bolster would hit the case before the edge could reach the sharpener. This is an annoyance, as a little of the blades are still dull. Keep that in mind if you plan to sharpen pocket knives with this. Also, applying pressure until the end of the blade make the knife cut into the case under the sharpener when it comes out. Not too big a deal, just thought I'd note that.I also used it on some kitchen knives that haven't been sharpened in a couple decades. The carbide side bit into the softer stainless steel more than the pocket knife, and had more resistance and removed metal per pass (so much so that I could see curly shavings on the table, I'd suggest not using the carbide side unless the edge really needs work). I got them very sharp too, and didn't have the aforementioned problem because the edge started further down the blade on these knives.Overall I'd say I got my 4 bucks out of it. I can see doing a few light ceramic passes to hone some blades from time to time. We'll see how long it lasts. Thought about giving it 3 stars because of the problem, but 4 because it's so simple and effective otherwise.

Worked perfectly, sharpened all my knives in a matter of minutes.

I go through several of these a year. They’re inexpensive and do a good job. The problem with these inexpensive ones is they don’t last very long. Typically, they last anywhere from six months to a year. This depends upon how long you use them. The nice things about these is You can use them on your expensive knives and they don’t ruin them and they do an excellent job on sharpening with both the course and the fine adjustments. I keep one in the shop for my fishing knives and one in the house for the regular knives.

Love smith sharpeners, always get the job done

Arrived on time and does what it should

This works very well. Hopefully it will last longer than some say.
