In Detail

The very coarse 240 grit stone cuts with amazing speed, but as is the nature of these stones, wears somewhat quicker than an oilstone. However, it can easily be re-trued, so this massive 205 x 75 x 50mm lump is going to last a long time. Use for badly nicked edges. Slightly smoother is the 400 grit stone (205 x 75 x 50mm), excellent for reforming the bevels on worn plane irons and chisels. Finally in this category is the 800 grit stone, a top quality Ice Bear brand stone and a real must in the waterstone armoury; this stone is used to flatten the backs of blades and form the edge. It leaves the metal dull but smooth. The 800 grit also measures 200mm x 63mm x 30mm.

It's Great!

Don't whinge about this being a soft stone that wears too quick. Course material generally is less dense that fine water stone. If you ride the chisel on water and let the stone do the cutting (not your lack of patience), you'll get great results.
I bought this stone for lapping some Japanese chisels and it's great!

The description of " wears somewhat faster than an oilstone " has never been more true !
Having recently bought a 3000/8000 waterstone ( and being highly impressed) I decided to get a 240 grit for repairing knicked edges, what a wasre of time and money . Yes it does cut fast but it wares out about 100 times faster, a cambered smoothing plane iron may be one thing ( assuming thats what you want) but cured wide chisles are another , used with a mk2 veritas honing guide the roller is constantly riding up on the slurry created as the stone wears away in front of your eyes . I would have scored it zero if that had been an option.
Don't buy corse japanese waterstones they are just too soft , get corse diamond stones and finish honing with 3000+ Japanese waterstones , that's what I'm going to be doing ( an expensive lesson learned)

Flattening Fast

These coarse stones will quickly flatten plane soles, plane iron backs and chisel backs or grind out chips and bad grinding from the bevel edge. Much better than any other method I have tried. Keep them in water in a plastic food box with a good seal and clip on lid adding a drop of bleach will keep the water sweet for years. Keep stones flat with ceramic flattening stone or coarse wet & dry on plate glass sheet.

Sharpening made easy

Moving from the various grades of grit you can achieve a fine edge very quickly prior to moving on to the polishing stones for the mirror finish.
A great result using the honing guide

Very quick cutter.

The 240 grit coarse water stone is very effective at re-grinding edges. A task that might take you a whole day on a regular stone, only takes half, if not less. It is very porus - soaking up a lot of water. It needs wetting after every five or so strokes, but it is very very effective. A must for any kind of serious edge grinding.
