Review on Lansky 2D2C Diamond Ceramic Four: Ultimate Sharpening Solution for Precision by Deron Altman

.but seriously, keep children under 10 away from knives. This sharpener is amazing. Words cannot express how much better and more effective it is than tiny pull-through pocket sharpeners. To the point where I will never use one of these again unless the weight of the backpack forces me to rely on it. Simple and intuitive to use, it seemed to sharpen my knives well, even those made from heavier gauge steel which is harder to sharpen. It's lightweight and the side pivots to reveal four rod storage compartments. No lost parts, no learning curve, just a good and easy to use sharpener. It feels like it weighs just under a pound, about the same as a second knife. It's not light enough to justify a trip of just a week or less, but if you're planning on using the ax for firewood in a long-term (>1 week) survival situation, I think it would really justify the weight of yours Pack. I wish they would come out with a lighter version with hollow bars and a lighter resin block. I bet they can drop the weight down to half a pound.
