Title: Not good for all waterstones like advertised.
Product review: This product looks good and has a nice big size. I comes in a hard plastic box and works well on stones 1000 grid and above, but it is advertised as a good choice for all waterstones. It does the job somehow on coarse stones like 320 grid but you better have a couple of beers next to you and some time to spare, because it took me over 30 minutes to flatten a stone that was not that bad. DMT is better on this if you use coarse stones.
Would you say this review depicts the product in a flattering or unflattering light?
