After recently buying some water stones I was looking for a diamond stone to flatten it and was wondering if there is any advantage to get a better quality diamond stone or a chepo one from ebay http://www.ebay.co.uk/itm/3PC-Diamo...t=UK_Hand_Tools_Equipment&hash=item5651c3766f also dose it matter what grit i use ? should i use a coarse medium or fine stone ?
Cheers.
