Lansky Fine Stone.
Ultimate finishing stone for final step in sharpening the highest quality cutlery.
Mounted on specially designed color coded holders with comfortable slip resistant finger grooves and are embossed with grade of stone for instant identification.
The original and still the best sharpening system you can buy.
This is probably the only system that is still made in the US, everything else has been farmed out to China.
It really will sharpen any tool to a shaving sharp finnish in minutes. I have been using a kit for years and haven't even had to replace the bottle of honing oil yet. A real winner.
