Thread: Coticule finish, sans slurry

I USED to hone that way on coticules. I should back up--

I've been posting a lot lately. As one member put it, I'm late to this old party! But I've been knocking out killer edges off my coticule lately.

You can get suction without running water. Seriously. Dr. Matt pointed me in the right direction, but ultimately, I prefer a coti after bevel setting. Dr. Matt's method relies on a predicate edge being done on a 5k stone. It's really not that far off from what Solitary Soldier's been getting at, just set the bevel and hit the wata! I don't have a 5k. I don't even think the suction has to do with cotis exclusively --I recently got the exact same suction on a Chinese 12k. Keep the stone REALLY wet, not kind of wet, not moist, im talking WET, and boom, the razor sticks.

You can get suction on a coticule using no pressure keeping a LOT of water on the hone. How? Dilute heavy every ~20-30 laps. Dip the razor in water, use a spray bottle, dunk it in koolaid for all I care. Want more suction? Do circles instead of X stokes.

By the 3-6 set, depending on how slow the coti is, believe me, it will suck into the stone. Try it. It works on BBWs too.
If the bevel is set the razor will squeak, and eventually the stone will pull the razor so hard it can't move. Love that feeling. Yes, every coti is different -- all six of my garnet style stones will do this. Recently, on a soft ark with slurry, I got suction with the 20/dip the razor sequence.

I like his video because it opens up a convo about slurry and convexing the edge--that auto slurry could be equally devastating as the slurry you see on top. If you take a coti slurry on a black ark, no dulling. You take a coti slurry on a CNAT, no dulling. You take a coti slurry on a soft ark, no dulling. But if you use coti slurry on a coti, Welcome to Tijuana! (er, Belgium).

I found another way recently. I still dilute every 25 or so laps (I can't count anymore!) but I use torque. No feedback unless I back up on pressure, but if I back up on pressure, I risk convexing the edge. With torque and frequent dilutions, I can get a much better HHT response.

The idea behind the way I hone is to actually USE the auto slurry, not dismiss it. Just keep diluting.

I should use just water on my stones after setting the bevel and see what happens. Not a bad idea or experiment. The suction, ah man I miss that! But with torque I never felt the need to find a faucet I can hone more under.

But yea, his post was epic for me. What I didn't like was that he later came up with a modification of his own modification which was actually a modification of a modification of several modifications of how to use coticules. The rabbit hole goes deep. Torque was the rope I needed, at least for my hone.
