The differences among finishing stone.
At first i should say this is for advanced people .
Some of you may be disagree with me . It is ok. i want to figure out this idea myself.
(All conversation is about final edge)
I always was thinking when you get the edge from stone they are all same.
what i mean by that.
when you get "v" shape of the edge your blade gets it is sharpest point.
i have done so many times getting 'v' shape out of the edge then not stop in there.
just push more to see what happens to the edge.
i have gotten in sharpness stage that edge just too fragile to hold anymore or if blade ss blade just melts.
Now i mostly finish edge an Escher and i know eschers edge very well.
if i check it on microscope i know in which stage i am at.
is this blade shave ready or not or i have to hone a little more etc.
All above was my understanding.
After messing around with Japanese stones more then over year now i am getting a little different opinion.( again i could be wrong)
Specially after my Japanese stone .
what i have done is this.
i used that stone to finish the edge on 4 razor.
Blade does pass my sharpness bevel test all 4 but when i check under the microscope i am having problems to figure out this blade is shave ready or not.
My difficulty is this. Edge is not same as escher's ,cf,or coticule or any other Japanese stones which i have used before.
This edge is similar to picture stone number 3.
it seems like i have taped the spine. In fact i have not taped any of the blades.
I will post pictures(simple pictures. you will see the differences edge stone leaves)
what i want to ask is any of you have similar experience?
All 3 stones edge will be same sharpness but thickness of the bevel different?
if this is the case
Lets say this.
we can use stone number 3 in picture and hone the blade which doesn't hold the edge (instead of taping) and have a great edge?
I never thought about this and i am not sure.
has any of you have a different stones which gives similar edge but different thickness of the (lets say bevel?)
Or something wrong with me?
i am not sure.
picture is how different edge comes out from different stones. stone 1 is narrower then 3.
sharpness fine in all 3.(including smoothness)
No hypothesis, but much interest - they do seems quite different.
My experience level does not provide any worthy guesses at why the wider angle, but it will be of great interest to see what thoughts come on this.
All of 3 wks w/ an asagi gives many more questions than answers. My stone is slow, but quite fine. It seems to not give normal feedback from tpt or hht like a c12k. I'm still very very pleased with the smoothness, but also have more trouble reading indicators as to when it's finished. 'Would love to hear from Lynn on this.
Crazy is the price of admission
Sham, your credibility is SO established - you can be as crazy as you see fit.
I hear about your edges from all over. So crazy or not, keep it up. The only normal people are the ones we don't know well. :)
I'm still wrapping my head around how the trailing edge of the bevel would get polished before the leading edge. Something has to allow slurry to invade underneath the leading edge and keep it lifted until the trailing edge is hone away, lowering to leading edge into contact w/ the stone.
