Is an 8”x2” oilstone wide enough to sharpen plane irons? Should I use a 3”-wide stone?

I was given a small, old, greasy oilstone recently. Is there any way to figure out what the approximate hardness is? In other words, if it’s an Arkansas stone, can I tell if it’s a Washita, a soft Arkansas, or a hard Arkansas?

You will not be able to sharpen the big blades from a 4 1/2, 5 1/2, 6, 7, or 8 as they are 2 3/8 wide, I wouldn’t sharpen on a stone that couldn’t fit the full width of whatever I am sharpening. A 5 and a 4 have 2 inch wide blades which places them on the exact edge of a 2 inch stone. Get the big stone, you will be thankful for it. Good Luck

Your oil stone is either 8” long and 2” wide – OR – 2” long and 8” wide. It’s your choice. :)

Compare the stone’s grit to known grits of sandpaper.

I sharpen all mine on a 2” oil stone. Move the blade from side to side as you sharpen if you use a jig. When working freehand I skew the blade to fit.

I haven’t figured a way to tell how hard they are, but I compare the ones I find in the wild to a waterstone (4000 grit) i purchased. I hope someone has a better idea.

It will be perfect for 2” wide blades! if you want to sharpen wider ones, turn it sideways and take shorter strokes. Use a piece of wood the same thickness of the stone next to it for your angle guide to ride on.

“Danielson… Show me side to side” Sorry, Don’s comment made me think of that…

I often free hand sharpen side to side… Its more comfortable grip for me.

I still haven’t got good enough to freehand a normal Stanley blade, the jig just makes it much faster for me. The thicker blades however I have. I can “feel” the contact with the stone. Also I haven’t figured out how to camber with the jig, so its a lot slower, but its freehand for me. The explanation here helped me a lot.
