sharpening stones

Posted at — Jun 13, 2016

I was watching a bushcraft demonstration of sharpening a bushcraft knife using a Nagura and  DC4. And having no appreciable skills sharpening knives I bought these stones right away.In the demo my mentor used the DC4, and a little spit to create a slurry from the Nagura. And after he was finished he wiped the DC4 on his pant leg and said one could use the Nagura directly on the blade. As I started sharpening my EDCs I noticed that the Nagura was getting stained. Luckily I bought the stone on Amazon and there is a way to ask questions from the seller.From what I understand from the seller’s response the slurry was the right approach. There is a need to keep the Nagura flat. Then again that might mean using a second stone to keep the Nagura flat. It was also recommended that the Nagura be carried in it’s box (not with my purchase) or in a ziplock bag.In the midst of the confusion I also purchased a WorkSharp.Keeping the blade at the correct angle is simple enough. At some point it should become second nature. It’s also small enough that it’ll fit in my pack without being a bother. In fact I’ll carry both.Finally, while a different bushcrafter commented that fire was nature’s TV he also said that knife sharpening your knife is just one of those things you do with your down time. It’s relaxing and calming.Making your own sharpening stone from sandpaper and carpet tape.<iframe allowfullscreen=" class=“YOUTUBE-iframe-video” data-thumbnail-src=“https://i.ytimg.com/vi/14hrK7XCpSs/0.jpg" frameborder=“0” height=“266” src=“https://www.youtube.com/embed/14hrK7XCpSs?feature=player_embedded" width=“320”>Mors makes the point…. 10 strokes on coarse, 30 strokes on fine, 300 strop. Watch the end of the video, stopping is meant to generate heat which knocks down the floppy bit. Stropping is meant to get the blade shaving sharp. If you can cut paper then skip coarse. a knife can be sharp enough that it cannot bite into the paper.According to Mors, a sharp blade can last 20hrs. I’m not sure if that means 20hrs of use or just holding for 20hrs. Seems a bit weak that ambient temperature and humidity would dull a blade in 20hrs.I’m getting some additional comments on the caring for the Nagura stone. Seems that creating the slurry on the DC4 is the way to go. On the other hand Mors demonstrated using double sided carpet tape and some high grit sandpaper to make my own stone. (and a belt as a strop).
