The guy told a sorry tale of how he was shafted by trend and another partner. It's really for touch ups rather than regrind and as such isn't something I'd use tending to trash my chisels as long as possible then tormek them.
Where do your sharpening problems seem to lie spectric? Scary sharp and the trend seem like short term things to me.(as does the veritas honing jig) quality diamond stones are very effective becoming slower over time. I've got dmt 2 side ones the first from America when it was over $2 to the £. After this got slow I brought a used but brand new one bundled with a no 3. If all I sharpened were chisels I'd probably get translucent arkansas or even lilly white washita.
