24, 46, and 80 grit sharpening stones

[Tom King]

These Carborundum stones are not sold as sharpening stones, but rather as "rub bricks" for tile work.  They're intended to be used to smooth down cut edges of tile.

I bought them a good while back to try out as sharpening stones for when I didn't have a grinder handy.

This afternoon, I sharpened four chisels that had damage to their edges.  I hadn't realized until I started to use it that my CBN wheel was worn to the point that it wouldn't put a pretty, straight grind on anything, so I drug these stones out.

They worked better than I thought they might.  It wasn't really much slower than using a grinder.  I don't think you want to skip grits though.  At first I tried putting oil in them, but it would probably have taken a quart to saturate them, so I took them out to use a water hose, which worked fine.

The 24 and 46 stones are a little smaller than I like, but they worked okay.  The foot long 80 grit's size is really nice.

I finished the chisels on my oil stones because I don't have my sharpening sink set up here.  The edge of that chisel in the picture looks like it's really screwed up if you zoom in, but that's a Big Honking wavy wire edge!!!  It cleaned right up starting on the purplish Washita stone.

I wish they made a 24 grit wheel for my mower blade sharpener.  That thing Eats metal.

I have a DMT diamond plate that is fairly coarse and it grinds way faster than it has a right to. And it's so much easier for me to control than with a grinding wheel.

I Hvw trouble picturing using stone that coarse on my chisels but, ...whatever works.

[Tom King]

I wouldn't let them touch the back of a chisel or iron.  These are carpentry chisels, and had hit nails or something other than wood.

I, like Tom, do a variety of things with chisels, such that I have rough work and fine work chisels. Thanks for sharing, Tom.

I have an old set of all steel offset Craftsman chisels that were dirt cheap. They get abused in all sorts of ways, yet will take a razor sharp edge. It's nice to have a set of beaters.

I love those black Craftsman chisels I have a couple sets I used them for years, not as my beaters on the job but, as my fine work chisels, setting hinges or chopping out mortices ( oh I have lots of beaters around ) the thing I liked about the Craftsman's is you can smack-em with your job site hammer
