OPST Chuck Tool
This tool can be used to tie both shank flies and tube flies. For this reason, it is the steelhead fly tiers' dream. By unscrewing the housing, you can flip the tool to work for hook shanks or for tubes.
The shank side will hold as small as OPST's micro shanks, which are approximately 0.9 mm in diameter. The Tube Adaptor's inner diameter is 2mm.v
