I don't think anyone is using slurry with this hone, it works fairly fast and as a finisher swarf would be very fine, terry says the darker cuts faster, I have a dark on the way the lighter one works well. very true you can find thuris and eschers but not as cheap as the apache, some want to buy a finisher and not have to buy it from a well known auction site. I like the apache edge, and for me it is that simple. if you are happy with what you have then you are right, why pay for one, it is all opinion. out of all the ones Terry has sold he has had one that maybe be a bad hone and he is going to replace it, if you should get a thuri and it be to coarse or just not a finisher would the personyou got it from stand behind it?
