Review: One of the best pocket sharpeners you can buy - Honestly this is kind of the best you can get for a pocket sharpener. 600 grit isn't idea for ultra fast rough work. If you had a blunt edge and need something to get you to working edge fast, i would want a very coarse 320 grit or even 220 grit. However if you want to keep your edge serviceable this is kind of perfect. 600 grit is fine enough to give you a keen edge, rough enough to do a little profiling if you are desperate. Simple system, nothing really to go wrong, quite durable and easy to pocket or toss in a field bag, so reasonably priced its not heartbreaking if you lose it. You do need to learn to sharpen though, this is totally unguided, but with a little practice and fairly steady hands you should have no issues getting at least a working edge. This sharpener alone is very capable of shaving sharp edges on well heat treated steel. If you are consistent you can easy do light passes alternating sides and break that burr off, negating the need for a strop, but a strop would be a good addition. Ultimately, this is the best one step pocket sharpener I have come across. it can handle most of your sharpening needs. I could be satisfied with this being my only sharpener if it came down to it. I definitely recommend. Review: Very cool tool - This as a well engineered sharpener. Screws into the protective cover when not in use, so it stays put. It’s just the right size for sharpening my EDC knives and it works like a champ. The oval shaped sharpener makes it easier to maintain a good angle, and in just a few passes my knives are as sharp as the day I got em, if not sharper. I love the portability. Easily fits a tackle box, glove compartment or pocket. I use it often and I don’t see any signs of wear on it. ## Features - KERSHAW ULTRA-TEK BLADE SHARPENER: Keep your Kershaw sharp!

Bought it around 8 months ago and very been pretty rough on it. **Q: Is this the same as a steel, like the kind that comes with kitchen knife sets?** A: No, this has a slight grit to it, you can feel it working . I use it for kitchen knives and my pocket knives. I really like this tool. **Q: How do you keep the correct blade angle when sharpening? 18 to 22 °** A: Well if your blade is wide enough, with a flat blade face, you could get one of those magnetic angle finder and stick it on the knife when using this sharpener. You also would wanna lay the rod horizontally on a leveled surface to drastically reduce any unwanted movement while being used. **Q: Will this work for sharpening a karambit knife?** A: You could for a quick sharpen. I use it for my utility knife blade. But for main sharpening I would use a wetstone. ## Customer Reviews ### ⭐⭐⭐⭐⭐ One of the best pocket sharpeners you can buy *by M***S on September 25, 2025* Honestly this is kind of the best you can get for a pocket sharpener. 600 grit isn't idea for ultra fast rough work.
