It erodes and gets no sharper at this point because sharpening and blunting has reached an equilibrium.Īt this point you start to dilute the slurry. At this point you can hone for years, but everything thats going to happen is that the blade gets less wide. So, in honing there is a optimum that is reached when the blunting is going as fast as the sharpening.
The honing at the 'sides' of the edge will go a little quicker when the edge is blunt, because it is a larger surface and the edge is actually getting sharper. If you make a thick creamy slurry you can hone a long time and this is what happens the abrasive particles hit the edge and will take away material, but at the other end they will hit the very apex right in front off and make it blunt again. with no slurry there is almost no sharpening activity.
If you take, for example, a Cotilule slurry stone you will see that: Slurry stones work 'different'' than other abrasives. Well, this is interesting and the outcome predictable. Now of course in the pass around you can also just look at these compounds on stropping media if you wish and check them against the common stropping/buffing compounds and that would be of interest and valuable.Įdited 1 time(s). In any case I am getting :Ī) 4 micron Diamond, used to load a 3K waterstoneī) 2 micron CBN, used to load a 8K waterstoneĪ) does the abrasive improve the honing speedī) are the edges sharper on a push or sliceĭ) can blades such as ceramic be effectively sharpened This is such a great idea I think I am going to pretend that I suggested it to him. Ken then suggested an idea so simple that it is almost child-like in solution, just use CBN / Diamond sprays on the same stones you prefer to finish with. This is also a fairly practical solution but my choice for finishing with stones has been explained in depth elsewhere but mainly condenses down into the massive hype/misinformation on stropping and the influence it has on producing low quality edges and frequent problems with stone/rod honing. There was an amusing exchange here when Ken noted that all of my problems were moot if I simply didn't have such preferences, which is true, stropping on a dense/flat medium resolves the issues. Neither of which interest me significantly for issues which are mainly personal and is a preference for edge into sharpening, This lead to some discussions of his solutions which include diamond films on flat glass and sprays for stropping. He founded the Schwartz Center in 1995 – just days before his death – to ensure that all patients receive compassionate and humane care.I have had less than ideal experiences with fine diamond abrasives recently (6 micron DMT abrasive : [ ) and after finding an interesting product which may have solved that problem ( Naniwa diamond water stones) asked Ken if he had used it. It would be a center that would nurture the compassion in healthcare, encouraging the sorts of caregiver-patient relationships that made all the difference to him. In it, he reminds caregivers to stay in the moment with patients and how “the smallest acts of kindness” make “the unbearable bearable.” His commentary has become a touchstone for the Center and readers all over the country and the world.Īt the end of his life, Ken outlined the organization he wanted to create. He wrote movingly about his experience in an article for the Boston Globe Magazine titled A Patient’s Story. He could have been any one of us.ĭuring his 10-month ordeal, Ken came to realize that what matters most during an illness is the human connection between patients and their caregivers. His case was riddled with terrible ironies. In November of 1994, Ken Schwartz was diagnosed with advanced lung cancer.
