Thread: BIG chip in russian ebay blade

Seriously ??? You said the chip was invisible to the naked eye. When I read that I thought even 1k may have been overkill. I'm almost thinking your honing was not reaching the edge for some reason, like a warp etc...
Shame you couldn't have taken a pic to give us an idea of the size.

Just to give you a point of reference I removed chips from a Henkels 5/8 Inox with a 1k Shapton Pro in 5-6 minutes of normal honing. Some of the chips were the full depth of the original bevel.

One thing to remember is that I am complete newbie when it comes to all of this and could be using really bad techniques on the 1k etc. But I have to to say this;after doing what I did I compared the look of the edge that was produced with one that sham honed for me and they looked very similar in terms of angles and "shine". again, I have no real idea what I'm doing and just experimenting.

all I know is that when I look under the scope at professionally honed edges I don't see jagged angles and divots. I want to make my edges look like those.

we'll see how good I did when I shave with it.

Not criticising your honing or inexperience. Just trying to prevent you getting into a habit of taking extreme measures that may create more wear than needed.

lol, there is plenty to criticise; as I wrote I am a total newbie and appreciate all your experience and advice. I do wonder why all the strokes on the 1k did almost nothing to smooth out the microchips though as others suggested they could.

If I'm taking chips out on a 1k, I've got some serious pressure going on. I'm not killing the razor, but I'm making swarf really quickly.

Maybe that's it. Were you using pressure on the 1K, or were you just using the weight of the blade?

Having breakknifed two razors and had to bring them back I can confidently assure you that if you are absolutely certain it needs to be done, 1. ask someone else. If they say no, take their advice. If they say yes, repeat step one. If several experienced honers say yes then you might have a case for doing it. Then ssk someone else, again, just to make sure. It takes longer to work back from than it does to ask fifty people if you should really do it.

On the other hand, hitting mosquitoes with a hammer is kind of fun. I also have teenage kids so my definition of personal pain my be scewed. ymmv

Breadknifing takes off more steel than it is necessary to remove.

probably not enough pressure by the sound of it.

Pressure has been suggested. Tho just how much is appropriate is a difficult concept to write about. Anything more than just right & you flex the edge away from the stone resulting in heaps of bevel wear & no edge contact. I actually find very little pressure works for me & if I'm removing chips I'll just make sure I'm using an aggressive hone.
Of course poor blade geometry can also make edge contact difficult e.g. frowns ,warps etc..

I don't understand that.

Say we start with a perfectly straight edge, with a chip in it. Two ways to fix:

1. Hone the bevel until it reaches the bottom of the chip.

2. Breadknife the edge until the breadknifed "edge" reaches the bottom of the chip, and then re-set the bevel.

The results -- the shape of the final razor -- are exactly the same for both methods. So they remove _the same amount of steel_.

PS - I've never breadknifed a razor; my _personal_ choice has been method 1. But I'm not prejudiced.<g>
