The 5 BIGGEST Sharpening Stones - Absolute Units!

[@theq3500]

I would suggest you guys add the king "big mama" stone while we're at it. It weights 3.5kg, measures 8x4x3 inches. It's a soaking stone which given the size, soaks for a good 30-40 minutes. It's not very practical as it's incredibly bulky, dishes relatively quickly and it doesn't work for high carbide steels. But none of that matters because the joy of using it on an everyday knive is unmatched by any splach and go I've tried. Also it only comes in 800-1200 grit JIS scale. I don't reach for it often given that i can't wait long enough for it to fully soak, but if i want to enjoy my sharpining session it comes first.

Thanks for bringing that to our attention, I'll check it out.

There is another. King makes a stone in 800, 1000 and 1200 grit that is about 8 pounds heavy, 230mm long, 100mm wide and 80mm thick. That is a serious brick but i haven´t seen it being sold anywhere but Dieter Schmidt fine tools in Germany.

the grinder stone looks interesting, I do fear it would be a bear to flatten

I like mine. It's an awesome stone. I use it for very long blades, lawnmower blades, and head shears. I use a solution of 4/1/1 of water, dawn soap, and mineral oil. Works great and no loading. I purchases a 2'x2' paving stone and some masonry sand to service it. If I let it go to long I do have a 2'x2' float glass and SIC powder to easily flatten it. It is a little friable, but it is silicon carbide. Bonding is hard. Medium to hard pressure depending on your angles. It's a great and unique stone to have in a sharpeners arsenal. Hope this was useful. CHEERS!

​@@JohnDoe-zb7dz Do you have any suggestions I have used my grinder stone and it seems that it glazed over. Any tips to keep it cutting?

[@JohnDoe-zb7dz]

@@powerai SIC powder is best on a piece of glass or masonry sand on a flat sidewalk. Worn diamond plates work as well. To expensive to use new ones.

@@JohnDoe-zb7dz awesome thanks for the quick response!

I don't blame you for mispronouncing that haha, it's a vowel junction. It's pronounced "Ah-oh-toh-ee-shee", because the etymology means you probably shouldn't combine the vowels

[@SharpeningSupplies]

Thanks! Hopefully I'll get it right next time!

@@SharpeningSupplies Also 'Naniwa' is pronounced Nah-nee-wah (old name for Osaka region). Incidently, 砥石 (to-ishi) literally means whetstone. That's an important one to get right.
