Yesterday I spotted near a pile of garbage some pieces of stone of the kind used to embellish the internals of buildings, most of then were broken; among them there was one still intact,

since it looks very plain and smooth I was wondering if it could be used as a base for sharpening with sandpaper or flattening the soles of the hand planes. Any thoughts?

I’d say check it for flatness and if it looks good, go for it. :)

Set a good straight edge on it and then try to stick feeler gauges under it. It may not be as flat as a real reference plate, but it could very well be flat enough for what you want to do.

Definitely check it. I have a couple granite slabs, one looks flat until you lay a straightedge across it, the other was good to go.

Thx Charlie and Rick, I’ll give a try; since now I have been using an MDF board with a glass slab on it, but this one has a better look.

I use a granite cut-off not unlike that. Works just fine for me.

Same here. Check it for flat and then go for it. Should be fine.
