Not sure why I've kept these, as they remain unused. From memory, left to right, first two pens were given to me by a kindly budding woodcrafter in the US called Howard, then two by Chris Yoke (the darker one has a genuine mastodon ivory ring), then an ergonomic holder by Melanie on Etsy (who seems to have stopped making them), a Curv-E by Edward, and something by Unique Obliques? The one at the bottom is of course an hourglass holder from Paper & Ink Arts.
There were more, but some were given away - a couple of Strahms and a couple of Curv-E travel-size holders, if I recall correctly.
If ever there was a case of nice instruments being in the wrong hands, this is it.
