Thread: Chamfering the edges on a Coti

It was shaving OK, but was just starting to tug a bit.

I had just received a roll of Kapton tape, which I had never used before. I had always used 3M electrical tape. My understanding is that the Kapton is a thinner tape. I figured that would mean the secondary bevel I had from the electrical tape would be at a different angle from the one formed using Kapton, so I decided to go back to the beginning and reset the bevel using the new tape.

I use just a layer of Kapton Tape as well, I like to get as close to no tape honing as I can but not cause any spine wear and the Kapton is very thin but lasts well.

If I want a micro bevel I add a layer of electrical tape over the Kapton for the finish.

As Tristan said, by creating a micro bevel I can try different finishes (Dry/Running Water etc) without needing to drop back, just add the Kapton and electrical tape again and rework the micro bevel.

Yes, Kapton is a nice hardwearing tape, just be sure to apply it long enough that the back end is past or close to the stabilizer, or a bit longer than electric if using over electric tape, it can roll up on you.

It is thin and easily sticks to itself. Make your life easy and get a tape dispenser from the dollar store. It also makes it simple to hold the blade up to the dispenser, pull out the tape and measure exactly how much tape you need.

The difference in bevel wear between, Kapton and electrical tape is not that much, and a bevel will flatten out in about 20 laps. Glen has a tape no tape video where he compares honing with and without tape and how many laps it takes to effect a change. I forget the number, but it was not a lot and I think he use a 4 or 5k.

A micro bevel is less than 10 laps, about 3-5 is good, anymore you have a double bevel and more, you have changed the bevel completely, not that it matters to the edge.

I finished on my LPB, using hibudgl's method because I'm often times too heavy handed, very good trick and got a very good edge, probably the smoothest Coti edge I ever gotten

@Tristan: interesting study on coticule and BBW you discussed. As your link didn't work when I tried it I copy-pasted it here:
file:///C:/Users/User/Downloads/BBW-study%20(3).pdf

I did not know the study. Interesting especially because the garnets in the BBW are twice the size of those in coticules: http://www.coticule.be/faq-reader/it...garnets41.html

I tried different finishes on my La Grise,
for me personally I have found that finishing on plain water on the Coticule gives me the keenest, smoothest and most skin friendly edge.

The BBW on light slurry also gives a great similar edge, although I found my Coti edge to be smoother and easier shaving.

The BBW on plain water wasn't that good, felt too crispy.

The BBW dry was also good, very keen, but not as smooth as on light slurry.

The Coticule on plain water is excellent and easily wins for me, easiest shaving, very keen.
Feels keener than the BBW on light slurry, is the smoothest and skin-feel and skin friendliness is the best.

Coticule dry is similar as on water, but crispier feeling, bit less smooth and a bit less friendly for my skin.

Coticule on slurry was too crisp for me, didn't shave as easily.

This is a highly subjective thing, but these are MY observations for MY stone, MY razors, MY skin and MY technique.

Just gotta find what works best for you.

Well, I have been experimenting with my Coticule edges.

Dry with Crox
Running water with Crox
Dry without Crox
Running Water without Crox.

I found the nicest keenest smoothest shave was running water no Crox.

UNTIL

Gssixgun, said he felt that running water and washing away the slurry was counter productive, I have to admit I had my doubts based on what I had read online that made sense to me.

Anyway, because I am just working on the micro bevel, I sprayed my stone up and made very little slurry as a starter because as I said it was only a micro bevel.

I did 15 laps with light pressure, and I did 20 laps weight of the razor. I didn't add anymore water than the original spray so I was playing in a small amount of mud.

I did add a layer of Kapton because that is how I hone and also a layer of electrical tape for the micro bevel.

I should have known better than to second guess gssixgun, I apologize Glen. I just had the smoothest shave yet and I think I have the Coti cracked now.

I have found that however you finish with a coti, fabric is your friend.

Just goes to show that slurry does do great things, even for the finish. Who woulda thunk it.
