My DC3 bubbled first then a chunk fell off!
.
I would second the DMT Diafolds, the red/green is perfect for touch ups, followed by a loaded strop if wanted, the red/blue will restore a damaged edge if it needs a bit more work.
Good quality, easy to hold and use and very effective. I never bother with my DC4 or sharpmaker these days to be honest.
Cheers, Paul
Have a look at the DMT Diafold Red Blue, with the DMT DMG jig for folders.
