Thread: Question for JimR: "False Edge" definition...

First of all, good on 'ya for translating "Honing Razors & Nihonkamisori"! Amazing to read that document! Big thanks are in order!

I'm curious about a phrase Iwasaki says a lot: the "false edge". He clearly differentiates it from a standard wire edge, so it seems like it would be something else. It sounds almost like super-fine microchipping or some kind of micro-burr, but I have no idea, really. Am I warm or miles off?

Is not micro burr a wire edge?
He is talking about the fine serrations left by the finishing stone, those define the "false" edge.
He then talks about using CrO to remove the serrations and create smooth (as in no serrations) even edge.

Thanks very much for the kind words.

I think what Stefan says is mostly the truth, but I still am not sure. To be honest, I still have yet to find any serrations left by a natural Japanese hone. I wonder if the False edge refers to a phenomenon caused by the enormous amounts of pressure he uses when honing Kamisori.

I've read the document (which is just amazing !! Thank you so much JimR !!)

From what I understand, he talks about removing the false edge for Komisoris as well as razors.
Since he uses mettalurgy microscopes to look at his edges, he must have seen things that we are probably unaware of.

Whatever he saw was removed after the CrOx & the 1mm back & forth movement on his last finishing stone, so I'm tempted to try that to see if it does anything for me. But instead of doing it free-hand, I'll put a few layers of tape. I wonder if it'll work for me.

I'm still wondering why it would take do much time to do that last finish step...

JIm,
I am in agreement here, for me from my finest stones the edge is ready to shave no stropping recuired right off the stone.
May be what Iwasaki is talking about is Kamisori, because they are made from harder steel and that might have an effect, that is the only thing I can think off.

i didnt understand this edge finishing. how should i place the edge on the stone and move 1mm? could someone make a picture?

Sicknote, I translated what was there. There are no details--it's something you have to investigate.

I think he talks about making a microbevel.

jea thats what i understand. but how, that i do not understand,

jimr: the translation is great!! thank you for this. standing slightly on its edge. hmm what you guys think he ment with this?
should i just hold the spine bit higher or should i stand this on the edge and should be moved just 1mm for 10-15min. doesnt it get dull then? hmm

Timo, that's exactly right.
Not standing 90 degrees, that would dull your razor.
