If those stones are 50-60 yrs old, they may not be 'carborundum'. This may be true especially if they seem to be 'smooth' and 'oil filled'. Before carborundum there were 'other' abrasive stones. None of them were as 'course' nor as durable or effective. But with patience a very sharp edge was possible using them. Some of them are very 'fine' and may seem to be 'smooth' to the touch.
If you do not like kerosene, try mineral spirits.
