Victorinox4.3323-X1 Pocket Knife Sharpener Perfect Portable Solution for Sharpening All Your Straight Blades in Black 9.1 inches

Easy to use with a little practice. Works well on Victorinox blades as well as most other blades. The "channel" down the middle is for sharpening fishing hooks. Unlike most sharpeners, with this one, you use the blue stone part to do the majority of the sharpening and then use the V-notch part on the top to finish. Other sharpeners want you to drag the blade through the V-notch part first. This sharpener has a much better design than those and that is what allows you to use this one in this sequence. It is a great size and weight. It is very portable and not heavy at all. It is built very well. The cover caps protect it and can even be used as a handle while sharpening. For the price, it is absolutely unbeatable.

This pocket-sized knife sharpener is a great whetstone for Victorinox pocket knives and even sharpening kitchen knives, although a proper whetstone is probably ideal for larger knives. It is small enough to take up barely any more space than a pen in an EDC case, and for the frequent sale price of $10, it's a great deal. It takes a bit of practice to master, but after a bit of trial and error, you'll be sharpening your knives with ease.Overall, does it's job well.

Very portable and light weight. Can sharpen a variety of blades. The main stone is thr perfect coarseness to bring blades back to a good edge. Very well designed and useful. There is also a center groove down the middle for fish hooks. Also makes a great gift.

So I am an avid knife sharpener. I have expensive sharpening systems and know how to freehand sharpen. I wanted something to be able to take out in the field with me to touch up blades while field dressing. I took one of my benchmades and dulled it on purpose to see how well this would sharpen. This brought back a dull blade that wasnt able to cut paper to a blade that was able to slice through paper fairly easy. Its not something you buy to get your blades razor sharp but it works fine for getting a sharper edge on a dull knife in a pinch. Theres a ton of youtube videos out there proving the "V" notch does nothing to sharpen blades. It would have been better if there was just a ceramic rod on one side instead of the ceramic V. So I took one star away. The correct way to use this is to hold the rod at a 25ish degree angle on a table and slide the knife straight down as if you're trying to cut the sharpening stone. Maybe 30 passes each side and repeat. Then light passes alternating sides to remove the burr. You can slide the knife through the ceramic notch to pull off any loose burrs but it wont sharpen the edge any further.

perfect small sharpener for touching up an edge in the field - its not good for a main sharpener for home use but its small size and easy to use makes it great for throwing in a pack

Works good, it'll give you an edge but, make sure you get it wet because it will pick up the steel dust and get stuck in it like all whetstones

Excellent design, portable, SHARPENS knives perfectly

Great piece of kit to quickly sharpen and give your knife a decent working edge. Biggest advantage is the size. With the thickness of two pencils side by side, and length slightly longer than a regular pen, this is easy to carry and add to any tool bag.Was easy to give my spyderco with vg10 steel to paper slicing sharpness. Would still recommend to strop after, but even without stropping it still gave it paper slicing sharpness. If it can sharpen vg10, it’ll definitely sharpen victorinox sak steel.Be aware this is with a knife that wasn’t super dull. For really abused knives you’d probably need a more robust knife sharpening system. But for edges that just need a quick touch up this has been a great tool.Quick tip: use the area of plastic where the ceramic stone is attached for a quick edge angle guide!
