Default bench grinder info

Hope everyone's having a good holiday so far. anyway, finally unboxed the bench grinder which I purchased a year ago. never had the need for one until my neighbor told me that it would be very useful for certain things. like sharpening knives and stuff. well the thing comes with two sharpening stones. one is composite and the other is aluminum oxide. which one do you use to sharpen knives with? I also saw a bunch of you tube videos and they're very conflicting as to which direction the blade should be facing. some show the edge of the blade facing the rotation of the stone and others showing the blade facing upwards against it. Thanks

I have seen them both ways too. Cutting edge away for the stone rotation will leave a burr on the blade. Opposite, very little burr. What grit are the wheels?

I tend to use a hand stone most of the time since it is easily controlled vs a spinning stone. If you are putting a new knife to the wheel to form the edge, I would use a grinder too. Just not for touching up the edge.

What are the # Grits of the wheels?

36 grit is a bit rough will take a lot of meat off the edge
I know a knife maker here and he only uses narrow belt sanding machines has three with various grit belts but that may be only part of the proses an i haven't see him using a bench grinder with a 36 grit wheel so all i can tell ya

And grinders don't work for my flint knives they sort of defeat the purpose

I would never sharpen a "good" knife on a bench grinder. Maybe if you're re-shaping or something but for actual sharpening a powered wheel is too aggressive...

it's a variable speed grinder. I'm using it to sharpen my first home made knife. I'm not a professional at anything. but like to try new stuff. one day I was off and got restless. went into the garage, saw some stuff lying around and said hey! why not try making a knife! never sharpened a home made knife before. the blade is kinda rough. just seeing if I can do this. Thanks

I agree with others, 36 grit is way too aggressive to use for sharpening.
