Bevel Tip and Magnification

ya, I think that bright line along the edge is exactly that, a rolled edge. Nothing more than being sloppy, I think. If anything, it's caused me to smarten up a bit about it. It could also simple be polishing on the edge from stropping. I'd stropped that one on the nappy side of my Kanayama linen, which seems very grabby and also seems to give a good boost to the HHT.

I'm kinda driving myself crazy with this microscope thing:D It's hard to tell exactly what it is I'm looking at sometimes, and just how much of it is out of my control.

For a side-by-side comparison here are two photos, on of the Double Duck from Denny which is the single sharpest razor in my posession, and the last result on the J. Haywood. Note that there is some texture to the edge of the DD, even though it is still getting a HHT5.

so... what's the word on posting photos to the thread? should I keep adding to the photobucket account, or should I post some in the thread itself? It would make discussion much easier if they were in the thread, but I'm not sure how it effects the site, other than being a pain to have too many photos here.... what's the netiquette in this situation?
 
First of all I think you drove yourself crazy a long, long time ago. Heated Coticules? You didn't get that from me mentioning the hair dryer and stropping, I hope.

As for the pictures, in the thread is much better for the reader, me. I am now having trouble with Photobucket since it starts up with "Satisfied" website or something and I can't upload like I used to. I know it is just something very simple and I have a bunch of time on a layover this trip, so will get it, maybe.

Hey, Gerrit Von Comer, head's bigger all the time. Gonna go shine the Rune now. Denny
 
No problem linking pictures in a post. I don't think they count on our data traffic.

I too think that 1/17 and 2/17 show a bend edge tip. On 1/17, there's what looks like a thrown shadow, just above the anomaly. Furthermore, a microbevel induced by a strop (I don't even think it's possible with an unpasted strop) would have transitional border, instead of the abrupt one we see here.

I think the small chips we see are just that. Small chips caused by honing. If you can't love with them, you could try manmade hones. With there highly uniform particles, they might be able to avoid chips, or leave a more repetitive chips pattern...:)

Perhaps they're even an attribute of the brisk/engaging/mellow properties of Coticules. Your magnification is higher than what I get with the stereoscope, hence I can't really tell.

Kind regards,
Bart

Correct. With the current configuration, they do not unless they are hosted by coticule.be.
 
Well, chips or not, that J. Haywood shaved like a dream! One of the nicer edges I've shaved with. I can't remember exactly anymore how it compares with the job Gary did on it, though I think it was just about as nice. If memory serves, he may have done it up on his Les Lat. The one impression I have held onto is one of incredible smoothness. It's funny how our markers shift a bit with time. When I'd gotten that blade back, it was the single smoothest and sharpest edge I'd used to that point, but I think I've come a ways since then.

Now that you mention it Bart, it's probably a good idea to do an edge up on my one remaining synthetic. It's a Suehiro 8K, and I'd come to the conclusion that it was designed to cut a jagged edge into the blade, but it's been so long since I've used it it's tough to recall. It should be interesting to hold it up in comparison to another edge done on a coticule.

BTW, I've smartened up on my stropping too, as I'm convinced I'd rolled the edge somehow.....
 
I have to say that my edges look similar to yours under high magnification. I always wondered why the edges off my coti's look more (might i say) jagged under a scope that coming off a synthetic hone. If I look at a synth edge under the scope it is perfectly uniform with no sign of any 'jaggedness' at all, if I hone with the coticule, the edge is still perfectly uniform but there are what looks like the slight bumpiness to the edge like what I see in your pics.

I guess it doesn't matter though, they shave better than the synthetic edges. Anyone else experience the same thing?
 
Well, ya'll got me to wondering, so here it is: 25 photos that document the process through every step of honing with my synthetics. I started with my test razor, which has a crack in the blade and had suffered a fair bit of abuse. I hit it with 30 laps on the DMT1200, rasied a burr, flipped it and repeated, then did a bunch of light half strokes before moving onto the the J-fake 1K. I struck the edge off on the edge of the 1K to clean it up as it was very jagged before moving onto a progression of 4K, 6K, 8K, 12K, CrOx, CeOx and the linen, bear-hide and vintage shell strops. The blade gets a solid HHT4, but feels rough on the inside of my forearm (by which I mean that it leaves a slight burning sensation)

I'm giving the link to my photobucket album because there are 25 photos in the process, and I'm too lazy to C&P the links to every one:p

As always... any thoughts?

edit: well shit. The order is all mixed up. Sorry, I have no idea how to re-arange them correctly so, unfortunately, I have to leave it to each of you to follow along according to the photo number.:thumbdown:
 
ah ha! I see. I'd added a description to the ones in the progression, but now I see that that doesn't show. Sorry, I'll fix that up ASAP.

edit:
Done!
I'm not sure why either, but apparently, only some of the descriptions were saved. I've noticed that before... must be an operator issue.
 
Although I have not been following this thread with as much attention as maybe I should, I cant help but notice the large looking crack, that runs up the bevel from the chip, its very clear in most of the pictures, and even the ones after the crox stropping, forgive me if I have missunderstood? but thats going to make the shave a little sore in places is it not.

best regards

oh ya, that's a crack.:w00t: A big 'un! That's why it's my test razor. And I have no intention of shaving with it. This was just an "academic" exercise to show wether or not the synthetics left a less textured edge, and I purposely kept it in the frame to attempt to gauge how much metal was lost through the process.
 
That's a burr. Intentionally raised by doing thirty strokes on one side only on the DMT. There are a few pictures that don't show the crack; in those ones, I was attempting to show the opposite side. In that case the burr is evident as a dark line at the bevel.
 
Here are some photos of the same cracked Shapleigh coming off my Okuda Aisa:
Starting off whatever the heck coti I used last time:

Auto-slurry off the Okuda Aisa and and variuos point in-between that and clear water:

Final edge:

It accumulated some damage as I went. Not sure from what. Stray diamonds from the EZ-Lap? Sure looks like it picked up a bump from somewhere.
HHT is really good; a 4, verging on a 5. Though, it says something about me that I'm honing razors I can't shave with:p

(boy, I'm really growing to dislike photobucket... anyone got any suggestions for other on-line photo hosting sites?)

Chris, Google's Picasa on the computer coupled with Picasaweb (on the web) is pretty painless (to me).
 
Chris,

Have you considered that the crack in that blade may cause instability and flutter while the blade travels over the surface of a hone? On the microscopic level we're dealing with near the very tip of the bevel, that might seriously affect your outcome. I would at least compare the edge condition near the crack and as far away from it as possible.

Just speculating here, I have no expertise in sharpening cracked blades;).

Best regards,
Bart

Good point. I am sure that a spot of corrosion on the bevel made it impossibe to get a fine edge. With that crack, you can almost see it in more than one plane. That can't be good.
