- n. a whetstone for use with oil
‘Sol Chickerel?’ said the man addressed, as he touched his plane-iron upon the oilstone.
The reciprocating movement of the tool on the oilstone or vice versa is continued until the burr is removed and the cutting edge has a bright appearance.
The burr produced is removed by alternately stoning the two bevels of the cutting edge with circulating movements of a wetted oilstone.
A specially shaped oilstone is required for sharpening the tubes.
Thereby the oilstone is moved by hand in a circular motion on the tool cutting edge.
If possible, the oilstone should have a fine grain.
In doing so, the scraper has to be drawn over the oilstone from either side of the cutting edge alternately and in an inclined position till the burr - which this way is bent for several times - is neatly removed.
An oilstone or water lubricated stone may then be used to sharpen the cutting edge.
And he got that whet rock, an oilstone, and sharpened his knife just like a razor.
Instead of using the oilstone an easier, tho less perfect, way to flatten out the burr on the edges is to lay the scraper flat on the bench near the edge.
