Hrmm. this is unexpected.

I just looked at the stropped edge with a microscope and I dont think my strops are going all the way to the edge.

They seem to be polishing most of the bevel face but leaving a Microbevel of the stoned finish left over.


This is the blade coming off the 1000 grit stone



And this is it coming off the 3.5 leather strops







What I see is the darker portion is the polish effect of the strop and its cutting off just before the edge and then leaving a micro bevel of the old grit pattern.

Thanks for making this simple test Spagery. I am surprised no one has does it already. Your results make sense.

there has been research done right here on the forums! ;) I can't remember exactly where it is but Clay determined that edge leading produced the sharper edge...

Check this out for one reference

And here are some more pics comparing the two...

Also note that due to the natural result of stropping (slight convexing) it is recommended to lower your angle by 1-2 dps when going from your stones to the strops... this will yeild a sharper edge!

Very interesting! what were the last stones you used before going to the strops? Dis you measure angles w/ an angle cube?

I put the knife in the clamp and ran the 1000 grit stones over the blade then I went to the set of strops.

But I didnt look if the angle changed going from the stones to the strop paddles.

With my setup I have the basic arms and I use my iphone 5 as an angle cube.

I will put the knife back in the wicked edge and and see the difference between the stones and the strops.

I did check the angle of the stones at the very start of the process with my phone to set both sides to 20 degree.


Stand by.

Reading the left side with ihandy level I get 20.3 with the stones and 20.5 with the leather strop paddle.

If that reading is correct then there is a different issue going on... do you have any kind of micro scope?

Yea I cant make sense of that because I would of thought it was the other way around.


Ive got a little portable microscope called an eye clops that goes up to 400x I took those images of the edge at 100x Its kind of touchy to focus it at high magnification.

When I first saw it I thought that the strops put a micro bevel on the edge themselves. But you can tell that the bevel is polished by the strops and that its leaving behind the old grit right at the edge.

I wonder if your iphone is off... try moving the strops out a degree or two and see if it hits the very edge. I normally strop at minus 2 dps and it still hits the edge!

Hrmmm...

I wonder if this has something to do with the metal being pushed back to the spine side of the bevel instead of being drawn out over the edge. Making the back side of the bevel fatter then usual.



Iam gonna strop the other blade done with trailing edge strokes and see what happens.
