Thread: Hone Use and ID Please!

I found a couple Hones/Sharpening stones lying around the house and was wondering if they are any good for a razor or what they would be used for.

I found some info from the web on the first one, but I'm not sure if it is any good for a razor or what it's use would be.
The first is a NORTON INDIA BENCH OILSTONES (Aluminum Oxide) Grit: Medium Size: 4" x 1" x 1/2" Norton Professional Sharpening Solutions - - - Bench Oilstones













The next 2 have no markings and have been used, 1 is broken. I have no idea how to tell what they are, so any ideas would be helpful. I think they are hones for razors because it looks like it is a set that comes with Razor Honing oil. (Might be a clue!)

The dimensions of the larger stone are: ~ 10.7 x 4.2 x 1.1 cm; Converted to inches: ~4.2" x 1.6" x .4"
The Dimensions of the smaller stone are: ~ 7.5 x 2.6 x .5 cm; Inches: ~ 2.9" x 1.0" x 0.19"













Thanks for taking a look!
