Natural Slate Honing Stone

Postby Pinch » Sat Mar 09, 2013 9:18 am

Hi All

I'm looking for a large honing stone and considering the many options out there. I'm currently looking at a Welsh slate with a slurry stone. I know it's difficult to measure the stone's gauge as every one will be different I guess.

Does anyone on here use slate as their honing tool and if so, what are the positives & negatives?

Cheers :D

Yes, I've just been looking at some lapping film, but I would rather go with something more permanent and fairly large - approx 300x100mm if this is possible.

I know barbers generally use slate to sharpen their razor blades and there's a guy (carpenter & joiner apparently) on ebay selling slate (Dragon's Tongue) who also claims he's been using the Welsh slate for years.

I have mixed feelings with it - but intrigued.

I use a piece of MDF and Solvol Autosol for a fine hone.....and the occasional bit of spit 8-)

I've got an old slate stone, about late 1800's, so it's had a bit of use. It is quite fine, I'd say about 6000 grit maybe finer.

Hmmm they do don't they... I must have had a blonde moment earlier.

But... I was reading a few 'barber' forums and many of them mention using slate. Perhaps they finish off on a leather strop.

I've sent the ebay chappy an email - looking forward to his reply.

Cheers Brian, do you find it's more labour intensive to sharpen on slate in comparison to a man made stone?

What I actually use for sharpening are 1000-8000 waterstones so I suppose that answers the question. My Dad used the slate for a final polish after an oil stone but I find the waterstones cut much more quickly. I don't think the slate is a soft as a waterstone so that should not be a problem (so speaks the man who carved a chunk out of a 1000 waterstone only yesterday sharpening a plough blade)
Cheers

To be honest I tried it a decade or more ago. I had not even heard of man made stones then so would not like to say. My recollection was it polished but very slowly and was very quickly no longer close to flat so I reverted back to leather and autosol

Thanks for the tips guys. I've now decided against the slate and I'm going to stick with the waterstone 8-)

Just want a biggen!
