Bacher Flattening Stone for Whetstones 220 Grit Fix and Reshape Damaged Sharpening Stones, Recommended #100 #8000 Whetstone

FLAT STONE, SHARP EDGE: A hollowed whetstone rounds the bevel and steals precision from every stroke - you press harder, the angle drifts, and only the high spots of the stone do any cutting. This Bacher flattening stone brings a worn, dished or uneven sharpening surface back to true, so your edge angle stays constant from heel to tip and the whole face cuts again. Use it on a stone that has already cupped in the middle, or as routine maintenance after every session to keep the surface dead flat - a stone you flatten regularly needs only a minute of work, a badly neglected one takes longer. A dished stone is not worn out, it is simply out of shape. COARSE 220 GRIT, JIS R6001 CERTIFIED: Cut from silicon carbide (carborundum), the abrasive that cuts quickly and wears slowly. The 220 grit is certified to JIS R6001, the Japanese Industrial Standard issued by the Japanese Standards Association - the particle size is verified, not merely declared. One coarse grit covers the whole working range, from #100 shaping stones to #8000 finishing stones, so there is only ever one face to reach for, and the finish it leaves is fine enough to sharpen on straight away. Quality is inspected by an independent third-party inspection company. FITS EVERY WHETSTONE ON YOUR BENCH: Levels Japanese waterstones, oilstones, natural stones, ceramic and resin-bonded stones, combination stones and bench stones alike - whatever the grit, and whatever you sharpen on them: kitchen knives, pocket knives, chisels, plane irons, scissors, secateurs, axes and garden tools. It also takes the glaze off a surface that has stopped cutting. One block covers the whole bench, so you are not matching a different flattener to every stone you own. Not intended for diamond plates, which stay flat by design and do not need levelling. DEEP, SELF-CLEARING GROOVES: The grooves run right across the working face - the face you actually rub with - at a set spacing and angle, so slurry and removed stone are carried away instead of clogging the contact patch. That is what keeps the cut biting from the first pass to the last and makes the result predictable; a plain flat block loads up and slows down. The 180 x 60 x 30 mm body gives a long, stable stroke, sits squarely in one hand rather than needing two, and is thick enough to leave years of usable material even under daily workshop use. HOW TO USE IT, STEP BY STEP: 1) Pencil a grid of lines about 2 cm apart across the hollow surface. 2) Soak both stones in a bowl of water for 10 minutes, until the bubbling stops. 3) Rub with even pressure, edge to edge, until every pencil line has gone - a lightly worn stone takes about a minute, a badly dished one up to 30 minutes. 4) Rinse both stones and let them dry standing on edge. Always work wet: used dry the surface loads up with dust and cuts slowly. The pencil grid is the surest way to see when the face is flat - the lines vanish last exactly where the stone stood highest., Weight: 1.10231131 pounds, Manufacturer: Bacher
