Tool ID help needed

This was in a box of old tools from a relatives estate. This is a sharpening stone of sorts but the radius does not match either of my axes or scrub plane. Any ideas?

Re: Tool ID help needed
Probably, the result of years of normal wear.....and the owner didn't have a way to flatten the stone after use.
Re: Tool ID help needed
It looks just a bit like a worn sharpening stone meant for scythes. There were a couple of the latter in my family's tool stash and a stone looking very much like that. I take it that it would be pocketed by the laborer using the tools in the field for touch-ups.
Re: Tool ID help needed
It is quite simply a two sided fine/course sharpening stone.
The owner used only the course side and obviously never flattened it.
Actually flattening is really only needed....in most cases...across the width of a stone so that when sharpening something like a plane iron or chisel the edge remains accurately straight and (usually) square to the sides of the blade.....but it is difficult....and unnecessary .... to flatten a stone without flattening in both directions. ( I know there are those who will argue that point....lol )

I'll try the flattening across the width of my waterstones next time since the distance is shorter! Cool..:-)

You don't need a fancy flattening stone to flatten it. A concrete block or even the sidewalk is flat enough to restore it to functionality.
Not in my lifetime...
Its a slow day here so I walked outside and gave this thing about 3 dozen strokes on a concrete block. Too much work! Maybe my neighbors sidewalk will abrade it faster.

Maybe you could find a friend with a machine shop and a Blanchard grinder? ;^)
Re: Tool ID help needed
It looks just like the one that was in my parents house for 60+ years sharpening paring knives. I used it many times to sharpen my mother's knives after my father pased away.
Re: Not in my lifetime...
Blanchard grinder?....The machine name sounds familiar.
Re: Tool ID help needed
This thread reminds me of a small, "simple" project I have intended to do, to save time walking out to the shop and back every time a kitchen knife needs sharpening. I have a spare horse butt strop and translucent Arkansas stone that I could relocate permanently to the kitchen. Thinking out loud: I'll need a box to protect them and a place to store the box, if it'll fit, maybe attach it to the bottom of the knife block? Maybe I can incorporate a place for an old oil can into the design, so I don't need to use the bottle of EVOO that sits out on the counter. So, I had to go back and edit quotes around simple. Since I'm a firm believer in the inseparability of design and engineering, this is starting to get interesting.
Re: Not in my lifetime...
Could you make a simple wooden jig that you can clamp to the stone with a 1/4" or 3/8" bolt facing up and then spin it on the concrete block with an electric drill?
Devil's advocate perspective......
this discussion makes me wonder about the concept of diminishing returns.......at what point is the value of this stone......given the expense, time, and effort of rehabbing the stone......exceeding it's usefulness?? Why bother with it if a new flat stone of similar size can be acquired at less cost......less effort??
The Devil made me ask!.....got to blame such a contrarian view on someone.
Re: Devil's advocate perspective......
I posted this as a joke but its made for a good thread. I have way too many stones to try flatten this one. I was able to flatten the fine side with ease so I'll put it in the carpentry tool box and use it for rough stuff. The kids can toss it when the time comes.
