Thanked: 10I use a belomo and a carson handheld microscope.
Sharpie test. It will give much information.
Strop
My last new coticule needed lapping, it was not flat.
Have you honed on coticule with slurry? Did you get a slurry stone with it?
As you finish decrease pressure on razor.

Lovely looking stone, Dobel, and I love your enthusiasm.
Keep in mind that using water only on most coticules does not do all that much to increase keenness, it's mainly to slightly refine and smooth out an edge. It also works as a touch-up for razors that start to feel less comfortable.
What is increasing the pressure from the tap supposed to do? I've heard about finishing under running water (not my favourite, as I found no difference compared to not using running water and it kept running down my elbow) but that is new.
Regards,
Pieter

Thank you very much Pieter! My first purpose was just a touch-up as you said because I believe it will be better for me as a beginner to make things step by step.
Regarding the water, if I'm not mistaken, using a greater flow of water should be a bit like using a higher grit number stone and allows you to finish better. I see you smoke the pipe, make yourself heard also in the appropriate section! Cheers!My English is elementary so I apologize in advance if on some occasion my tone should be inappropriate.

There is a lot more to it than you would expect. It sounds like you are being methodical and taking things cautiously. You have a good attitude so stay with it and read up on some ideas.

For your first try with a coti, well done. Nice looking rock there, too. Definitely lap it. It should be pretty close to flat, but the flatter the better. All you need is a sheet of sandpaper and a 12 x 12 polished marble floor tile or granite countertop sink cutout, or a very thick piece of glass, or a 12 x 12 piece of 3/4" thick acrylic from TAP Plastics. There are also calibrated granite lapping plates made especially for things like that, not too expensive but kind of overkill unless you like to be super meticulous for its own sake.
Obviously you did not need slurry for the razor you honed, but you should find another razor that is a bit more tired, raise a slurry, and gradually dilute it as the edge comes in. Tape not needed, depending on the razor. Running water is the finish. You can up your game by adding shave lather or dish soap to the honing water for the last dozen or two laps, after ensuring that all slurry is rinsed off. Works best with stones that don't auto-slurry much. This picks up the sharpness quite a bit. Light pressure is the key, and you may find that finishing with very short, like 3" long, x strokes also gives you a sharper edge. LIGHT PRESSURE is a key factor in final edge quality. Especially when you have added a buffering agent like shave lather to the equation. Such buffers will make the stone act like a much finer medium and require additional strokes. This is all introducing more variables into the honing equation and we all know that is bad, right? Except no, when you really nail it, you will be happy with the edge. I think it will all come together for you quickly though, from your initial success.

Ive read Glen saying many times to learn honing from the top down. Meaning to learn to touch-up first. Then step down a little more with time and experiance. Most of us dont listen. Lol. Good for you to want to learn to touch-up first. But to learn with a Coti seems way out of line. But thats JMO. Good for you and good luck. Keep learning and practising.
It's just Sharpening, right?
