So while watching a video of Mors Kochanski sharpen his newly created survival knife (I'll link the videos below) he casually mentioned that during the honing process he would go out and buy two cheap ceramic bath tiles and rub them together till they were flat. He would then use this newly lapped bath tile as a finishing stone. "Whatttttt?" I said to myself. So after fruitless googling to see if anyone had done this before I decided to take a trip down to my local home depot.
I picked up a small beveled edge floor tile for about $3. Already having a wet tile saw I cut it into the rough shape of my annoyingly coarse Fallkniven DC4. I then used my machinists block and some 60 grit sand paper to remove all of the grooves and flatten the stone. I started at 60 grit then moved to 150, 320, 600, and then ended on 2,000. Here are two photos next to the DC4: 
So how does it work? Well it seems to work really well. It is extremely fine, I was actually hoping it would be a little bit coarser so I could use it as a replacement to the DC4's sapphire "fine" stone. But what I ended up with was a very fine hone. I am not a very good judge of grits but I'd say its way finer than my Spyderco Fine stone and even finer than my surgical black arkansas stones. Have any of you done this before? If so, if I condition the surface with a coarser paper (600 - 800) will that make the stone coarser or are these meant for honing purposes only? Are there any downsides to this? It sounds like Mors has been doing this for several decades with no ill effect, however I figured I should ask around. Videos: Mors makes a survival knife:

I do alot of my honing on the bottom of my coffee cup But that looks cool I think this is the exact same concept of that just in stone form, although I don't know if they use different types of ceramic. Do some coffee cups work better than others or are they all pretty much the same? |
