hello friends...when i pass my razor on my coticule in the thumbnail test it is rough in the center of the blade...how i can correct this?
It sounds like the razor needs more work because the bevel is not there yet (or it could be overhoned). I use a 4K Norton until I get a perfect thumb nail test and an even bevel under the microscope; then polish the bevel using a variety of different methods. Setting a good bevel is the most important part of honing for me though. If you have some patience you could probably get there with just the coticule (you will want to use a slurry so that it cuts faster) but it will take more time.
Is this a new or vintage TI?
Try to take a look at the edge under magnification - what you describe may also be microchips (especially on a vintage razor; they will need quite some work on a Coticule to get rid of)
Good luck

this is a new TI
how i can develop a slurry? (i have only king 6000 waterstone and coticule)
i have made about 75 lap on my little coticule....14x 4,5 cm.....generally after honig and green paste mastro livi told me that i should " clear the bevel of imperfection" cutting an old jeans as a knife...until don t cut anymore...
Ouch! I really don't like the sound of that.Quote:

I am still puzzled - on a new razor the edge may be blunt, but not rough! If anything, it would feel smooth to the thumbnail, I think.
Maybe the Maestro was talking about removing a wire edge? You can also do it with a cork, or plain paper, etc. But I haven't seen a new razor with an overhoned edge / wire edge... Or was he saying he does this routinely as a final stage in honing before shaving? Can't understand

how i can develop a slurry with coticule?
thanks
A cotigura from Howard, a Naugura rubbing stone, a penny rubbed flat on the stone or a cheap metal blade will all create a good slurry when a little pressure is applied. The water will start to look milky. At that point you can be sure that the garnet rich slurry is ready.Quote:
