I have a couple of the sliding ring hand vises used by jewelers and watchmakers. They do not hold the hook very well. The other popular jewelers or watchmakers vise had a thumbscrew or a wing nut. These work much better. I am especially fond of the Eclipse vise made in Shefield England. A few early fly vise makers incorporated Eclipse vises in their fly vises. I plan to publish a book within the next six months on vises. If interested PM me and I will send you a note when the book is available.

" Fishermen, hunters, wood choppers, and others,
spending their lives in the fields and woods,
in a peculiar sense a part of Nature themselves,
are often in a more favorable mood for observing her,
in the intervals of their pursuits,
than philosophers or poets even,
who approach her with expectation."
Henry David Thoreau
