The last two post are well said and I believe expresses what Sham is saying and what I believe. My concern is the same in one instance and that's running the blade lightly across glass. I did that after checking the edge under 30X then after running the blade across a regular glass. There wasn't much difference at all.
I have one Coti that is soft enough to pass the test mentioned in the booklet where you use a fingernail and see if it leaves a mark. With that Coti water worked just fine in about oh 8 to 10 minutes I think it was. In other words what we would call a fast cutter. I was able to do a fair finishing job with light pressure. I still got the Escher out for the best edge:-)
I just wonder if some of these new methods don't wear a blade down rather fast.
