Thread: Dad's Arks

Well I'm not sure If I have a good handle on that referentially. To me all arks seem pretty hard but I think this one seems fairly soft compared to most of them that I'm familiar with at least which doesn't say a whole lot. It seems on the course side though. I smoothed the one side, I wouldn't quite call it burnishing, with a diamond plate (also my dad's) and leveled the other side with my silicon carbide Norton flattening stone. It left it fairly rough so I have a course side, a medium side and polished side. Oh, and to further answer your question Lou, I also have this from my dad.


This great big old toe breaker is what Dad used for razors (he owned a sharpening business) albeit not much that I remeber. That's the "cinder block sized" double sided stone I was talking about earlier. I'd really like to figure this one out. It has some kind of mineral which is blue greenish on the one side. It's probably silicon carbide although it could be diamond, I have no idea, and the other side is soft and porous. If you spray WD-40 on it the soft side soaks it up like a sponge and the hard side lets it pool and it never will soak in.
