Lansky QuadSharp QSHARP Blue, One Size

If you’re looking for a sharpener - get a line of Lansky stones first. Get their complete set - from extra coarse, to Blue Diamond, and a few leather hones if you also want your blade to look beautiful. That’s the setup that makes your blade sharp. This particular tool is a great FIXER, a good pocket size helper when you’re outside. Call it a heavy duty bandaid. It’s a bit too aggressive, even on a tough blade - but it’s build to last. You can use it on almost any cutting / chopping tool, and finish it with ceramic benchstone. It’s a great find in your pocket when you’re out there and need to bring back a good edge, quick. It’s a bit heavier than most - but it’s a solid aluminum build, with real carbide teeth. HOWEVER, it would take all the time and patience to actually re-profile the blade with this tool. It wasn’t meant to do that. But, as far as the edge goes AFTER their stones set - you need no more than 10 strokes to bring it back to life. Good buy. Works on anything - from a funny envel-opener, blade, fishing hook, scissors, axe. Will recommend (already did). Definitely well worth it’s price.

I’ve had a Lansky 5 stone set since the 80s and this little sharpener is a worthy addition to the kit. It’s very good at touching up the blades during and after use. Great for the field, keep it in your pocket or pack, and slick up a blade quickly. The multiple blade angles correspond to the angles with the Lansky 5 stone kit allowing you to maintain the same edge geometry.

First saw this at a trade show and then decided to get one after seeing it offered via Amazon Prime. QuadSharp is small but quite durable. The weight might not be great for ultralite backpackers, however it is handy for backpacking with others when they need to dress-up their knife edges. While I typically use more expensive Lansky sharpening stones or a DMT diamond assortment for my best knives at home, I've found the QuadSharp to be a nice addition to my EDC and for camping. Because it has 4 different sharpening angles, it can be used on most knifes. I tested first on several kitchen knives and found most needed only 3-4 passes to make them sharp enough for the "paper edge" test. The worst of the knives needed 5 passes. With this type of sharpener it's important to only apply light to medium pressure on each pass. I've found that first time user's tend to press much too hard on passes and are then not happy with the results. After showing them it only takes light pressure they got great results with only 3-4 passes. It has two Phillips screws that appear to allow changing of the sharpening blades if needed. Because they are so durable I had no need to try opening the QuadSharp to see if this was true. Why only 4 star rating? There were no directions on how to use of the QuadSharp. Although this was not a problem for me, the people I allowed to use my QuadSharp had problems because they started out pressing too hard when sharpening. Pros. - Easy to use - Good results with minimum of passes - Minimal space required to store & carry - Very sturdy - Handy lanyard hole - Color makes it easy to locate when packed with other items Cons. - No sharpening directions provided - Weight could be issue for ultralite backpackers

I grew up with knives and using whetstones, but the last whetstone I tried didn't work well for me. This is super handy though, especially with older kitchen knives. It makes a good edge and when it's done it's job, a leather strap will fine tune the edge to razor sharpness...I could genuinely shave with my large machete now, if I wanted to. This tool is a good value, no matter what you're trying to sharpen.

Small, compact and does a great job of sharping my knifes

I used this tool to sharpen my "everyday" duty knives and our kitchen knives that's a must when you have a wife and four daughters that loves to cook. I never thougt that using the Lansky QSharp can be that easy and gratifying. I like its size that allows me to carry it in my pocket and yet hefty enough and constructed with a very good balance that allows uniform sharpening motions. I was surprised that this can stand not only on a firm flat surface but on soft and uneven surface (like your bed) as shown in the picture. The first picture shows the everyday duty knives that i carry at work or around the house being a facility maintenance guy. Almost all but one will not easily slice through paper before I used the Lansky Qsharp. Two of these blades are over 25 years old. Can you guess which one (Steinbrucke, Buck, SOG or Leather Wave)? If you like knives, i highly recommend that you consider including this in your toolbox.

Very good sharpener. Very well made and great for in your home or camping

I like the full-metal case of this tool, but I found that it's not suitable at all for knives I *really* like. It's a field tool, probably meant for cheap hunting or utility knives. The multi-angled carbides *work* -- but be warned: they work very well and quickly; they simply shear along the sides of your knife blade, to the point that you will be able to see actual metal shavings sprinkle down on your pant leg. If you have a knife that has gone SERIOUSLY dull, this tool will QUICKLY re-angle that blade to something quite functional. But don't even try this thing on knives that are already decently sharpened since the carbide will wreak havoc on bevels still intact from the factory. With enough pressure, these carbide bits are extremely aggressive; the sharpness that results at the end of a few strokes seems to be a combination of re-angling and simply turning the edge of the knife blade into a microscopic saw. (This last is a very bad thing for good knives -- you'll need something else if you actually want a razor-edge on anything.) I also found the ceramic to be fairly gritty, though not as aggressive as I expected. But again, I can't use the ceramic on knives that are already decently sharp since it just isn't fine or smooth enough. I'll stick with my Spyderco equipment for nice knives, and use this for outdoor tools.
