Negative Positive
Title: Good so far!
Review: I bought these stones for the first time. The weird thing after sharpening the first time is that it does not spark when sharpening but they seem to work so far!The other thing is that I found single(1) for a 1.79 a pc. and I spent 8.99 for 4 pc (2.25 each) so I think buying singles may be more cost effective!To all, wear them safety glasses cause if any of those diamond chips fly off that dremel at high rpm, it could be nasty in the eyes, in my opinion.
