A friend sent me this joke that seems appropriate to share regarding stripping:


There was a bit of confusion at the store this morning.
When I was ready to pay for my groceries, the cashier said, "Strip down, facing me."
Making a mental note to complain to my congressman about Homeland Security running amok,
I did just as she had instructed.
When the hysterical shrieking and alarms finally subsided,
I found out that she was referring to my credit card.
I have been asked to shop elsewhere in the future.
They need to make their instructions to us seniors a little clearer!


So I think the give away here is "The edge now tries to saw the paper"

My guess is that the burr has broken off or partially broken off and you now have a jagged edge. THAT would give this sawing effect. You should go back and redo the edge with the stones, taking pains to remove the burr completely and make a minimal burr, removing it by gentle abrasion with lateral strokes. The edge should cleanly cut the paper. Now go on to the stropping. If you have a jagged edge from rough deburring you wont have a lot of success with stropping. The stropping itself may dislodge those cling-on burrs just enough to bring out the jaggies. It isn't essential but an 8k stone added to the lineup might not hurt.

Get one of these inexpensive loupes on Mark's sight - 20 x or so and closely inspect your edge before going on to the strop.

And then follow all the good advice in this thread while stropping.

Something has changed with the stone. It has acquired a sheen and repels water. It also is no longer uniform gray (1000) and cream (4000). I don't get it, but I can no long sharpen as I could ... not even close. Pondering the Shapton glass starter set or the 5 piece Beston 500, Bester 1200, Suehiro Rika 5K set. Any thoughts about relative merits of those kits?

I think technique is more important than equipment. I think if you want to upgrade your stones that is all well and good. If youre not getting an edge on the stone you have now, id say its most likely technique that is failing you. You can use this "buggered" stone to learn proper technique.

Have you lapped the stone with a diamond plate? It sounds like the stone has glazed. Also when using the stone use more water.

Glad you appreciate my humor :)

Good joke, even if HS has run amok;-) I don't think the problem is technique (alone) because I was slicing narrow ribbons of paper after previous sharpenings, especially my blue steel nakiri.
Stone glazed (interesting image;) is what I'm seeing. Why does it occur? A friend has a diamond lapping plate and I will try it.

Metal swarf gets stuck in the stone. With more water you get less glazing. Running a stone dry will nearly assure you of glazing. A diamond plate will remove that outer layer of stone with the metal swarf and flatten it too. You can also use another stone to rub it off. I use a small piece 2x3" of Atoma 400 to retexturize a stone which also removes the deeper scratches frrom flattening with a coarser diamond plate.

"I use a small piece 2x3" of Atoma 400 to retexturize a stone which also removes the deeper scratches from flattening with a coarser diamond plate."

I also find this EXTREMELY useful for raising a dense slurry on a medium grit stone, ESPECIALLY natural Nakado stones like the Tajima stones.
I plan on doing a video of this soon and will be getting s couple of these in very soon in full sized stones too.

I've become hooked on the little 2x3 atoma 140. I use it to clean the stone as I'm sharpening and it really works great. Most stones start loading immediately and giving it a quick rub down with the Atoma keeps it cutting well and helps keep it flat as well.
