Bevel Wierdness!

So I get this little Filar in the mail the other day, and pull out the stones to get her ready for use:

Attachment 197517


I lap the crap out of my new Chosera 1K as it was brand new. Did the grid pattern and all that to make sure I was flat.

Now, it takes 3 layers of tape to get this bevel going with the way I am happy with it, but do get a nice bevel. I take her to 5K SS and after a few circles, I see a spot where it looks like the bevel has jumped up a couple of mm in one spot in the center of the blade.

Here it is at 30x.

I was only using light pressure at the time to torque the heal.

Any idea what has happened here?

Thanks!

That hapened to me couple a times . Its hapening when the angle is slight on the 6/8 blades and the blade is too close to the stone . I often polish blades and after i hone them and aways hapened that way on the wider blades or when i use slurry on the synthetics . Somethimes a single particle can ruine the polish of the new blade .
Most of the times this hapened on Sic stones or on a softer ones . I didnot get such scratch only on Makita 1200 grit / King Deluxe 1200 / because is muddy and instead of scraches i get fuzy casumi spots nearby the edge .
Nice schorty razor by the way , i broke a brand new SI GI Solingen 6/8 and i cut it 1 sm - it was 7.5 sm now is 6.5 and its waiting for scales and honind . Is not the lenght that maters , is what they are made of .

I'm not sure what you mean by the bevel has jumped. You appear to have two distinct bevel angles along the entire visible length if the blade. Is that the issue? If so, the most likely reason would be that your tape wore down during the bevel setting and then you replaced it with fresh tape on the higher grit hone.

Thanks for your explanation! Good to know I am not alone. :)

No, I am perfectly happy with the double bevel.

I was referring to the odd pattern of darker scratch marks above the bevel in the photos. It is clearly visible to the naked eye, as if it is chipped (though it isnt).

A little added pressure is all it takes to widen a bevel. Especially if your working just a section of the whole edge. Your pushing the blade down towards the stone decreasing the angle.

I too am confused, are you talking about the dark spot on the blade?

If so that has nothing to do with honing, that looks like heat from buffing or grinding.

There seems to be a similar discoloration on the tang, but could be the lighting in the photo.

As an aside, 3 layers of tap is a lot of tape and can easily get squishy and cause weird thing to happen to a bevel.
I would go back to 2 layers of tape and see what the bevel looks like.

OK, now I understand. Maybe you should not have named this thread "bevel weirdness?"

I agree with Euclid, that's just a oops from grinding or buffing. Consider it a beauty mark and forget about it!

It actually didnt show up until being on the 5K for a few circles, though, leading me to believe I hit soft metal or something during the bevel set.

Either way, I shaved with it this morning, and WOW... The Fila hype is no hype. Most comfortable shave I have had from a straight since starting to shave with them last September! This thing cuts like buttah!

So whatever it is, sloppy hone, picking up rough particles already shaved off the blade, or beauty mark... it doesnt effect the shave at all!

BTW, yeah, I suppose the title is misleading. I made it that way since that "spot" showed up just after bevel setting, and shortly after putting it on the 5K. Without magnification, it actually DOES look like the bevel becomes humped there, but, under magnification, you can definitely see that is not the reality of it.

not too strange if it was already there, but very strange to be caused while honing. Is it possible that you were doing circles on the 5K and you ran the spine off of the hone?

I suppose that IS possible, though I usually dont get to the end of the stone when I am doing circles. I suppose when I was done and went to flip it over, I came off the bottom off the end of the stone. And that would explain it, if so.
