Use and cleaning (unclogging)
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean (unclog) with alcohol and toothbrush.
Maintenance is only needed every year or two to flatten stone or "open up" abrasive grains.
Maintenance of metal bond stones:
In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl):
- 10-20 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 5-10 mins polish movements (carefully draw "8") on glass plate.
There are other methods, but for metal bond stones the method with FeCl, on glass plate is the cheapest and simplest.
Maintenance of resin bond and combined bond stones:
Use SiC powders according to the table below

My listings of Poltava sharpening/honing stones (Length x Width x Abrasive Thickness, mm):
Diamond sharpening stones: not recommended for steels with high carbon content, but perform well with hard steels, like CPM S90V.
CBN sharpening stones: standard for steels.
Combined bond: next generation bond, combines delicacy of resin bond on fine grains, and wear resistance of metal bonds on coarse grain sizes.
Sets: preselected stones to make your choice easier: metal and combined bond sharpening stones on blanks.
Pro 200% - professional stones with concentration 200% (standard stones are 100% concentration), which means higher productivity and longer tool's life.
Economy: cost saving solution for most sharpening applications.
"Pro" and "Economy" are the only nicknames I use for stones and I suppose it's clear why. No pathetic nicknames and brands. Just product as it should be, from trusted Poltava seller.
