Bevel Tip and Magnification

hhhmmmm.... OK. You guys make a good point. The only reason I'm using the cracked one is because I can hone away to my hearts content and not have to worry about wearing it out. My good blades all have really nice edges on 'em I don't want to mess with, and I'm wwaayyyyy behind in my shaves :sleep:
The other rationale behind using it was to show how much steel is being removed with each honing.... my conclusion: hardly any. At least, not an easily perceptible amount. I'll go back and find the photo from the beginning and try to make some better observations. ( I wish I was better with graphics programs as I'm sure there are ways to apply scales and such to the photos, but I'll be damned if I know how to do it)
I can see that the two halves seem to have edges that come to different levels, but I can't see this speck of corrosion that Denny's talking about. I'm skeptical about it as this blades been on everything from the DMT to the J-nat. How a little speck of corrosion could have survived all that, I don't know. As for fineness, it'll pass a HHT4, easy.
I was struck by the apparent reduction of "texture" at the edge left by my J-nat compared to the coticules, but I'm baffled by the sudden appearance of those little flea bites. i'd sure like to know what causes them.
 
Sorry, Chris, I was talking about a piece of corrosion on a blade that I honed a while ago. Add your own zinger. I'm in a hurry. D
 
Hurry? hahaha. It's taken me how long to respond... you'll grow old... er, I mean older... waitin' on me!

Here are two more photo's, of my King Cutter with a "meh" kinda edge, coming off my Le Verte, I believe, and then coming off my BBW following the guidlines in the new study. (I'd already stropped before i'd remembered to take another photo:blush: ) I've increased my exposure time to try to add more light to the picture, to apparent good effect.

WOW! look at that BBW bevel :thumbup:

And "Older"

Bwhahahaha made my night! thank you hahaha

Thank you Chris,

The BBW bevel indeed looks smoother, but as you know, I don't adhere too much truth to magnified bevel views. We need to know how it shaves. Preferably side by side. Maybe you could add a couple stropping strokes on the La Verte as well, just to see what happens with the view under magnification.

Kind regards,
Bart.
 
Just an FYI... I finally got around to trying to figure out a scale (in a very analog way) for the photos of the "cracked blade"
I took two original photos, the first in the series and the last in the series, cranked the contrast and brightness up all the way to show an identifying feature in the crack, printed 'em, measured the millimter marks in the background, and determined (using an arbitrary scale) that there was exactly ten units between the millimeter marks in the original exposure. According to my math, that would make each mark the approximate equivalent of 10 micrometers (?). Measured from the same feature of the crack, the total blade width loss over three honing session totals (approximately) 75 micrometers. (0.75 mm).
So, for this blade, each honing session has removed approximately 1/4 of a millimeter. (0.25mm).
So, right away, I realized I could have figure the same thing out with a micrometer caliper, but I ain't got one, so I had to do it this way.
Today I'll try to get around to some stropping strokes on the Le Verte as Bart suggested. And I'm thinking of a photo-journal documenting the transitions from an original factory edge on my last remaining virginal Shapleigh to shaving sharp... just for the hell of it.
 
0.25 mm is surprizingly much. That would mean the Double Arrows of the BBW-study should be 2mm smaller than before the expreriment (8 honing sessions). They most definitely are not. In fact, considering how often they have been rehoned already, they should be gone by now. ;)

Could it be that your measurement has a high approximation error?

Kind regards,
Bart.
 
I think that's the most polite way i've ever been told I'm out to lunch!:D


Upon double checking my arithmetic, I think I'm out a decimal place, :blush: so my correction would show something more like .07mm blade width loss in three honing sessions, the first of which might be called serious bevel work, probably accounting for the largest portion of it.
In my own defense, it's not a very precise means of measuring, and I'm certainly not used to working in metric:p
 
hahaha
thats a relief, I did read the first measurement and think "jesus that sounds a lot" so at that rate I will wear out my 13/16th Palmera by the time I am......etc. etc.
