OPST Shank Chuck Tool:  A solid pinch/grip on the very tag end (approx a 1/4 of a cm) of this 2″, 51mm OPST Steelhead Shank.

OPST Shank Chuck Tool: Easily secure shanks into vise. You have seen it (or a prototype of it) in OPST fly tying videos. You have called and emailed and asked about it. And now it’s here: the OPST Shank Chuck Tool. It took OPST a long time to dial this one in. The challenge was first, to make a tool that would fit with just about any vise on the planet. They succeeded in doing just that. The second challenge was finding a tool that can secure both shanks and some tubes- by unscrewing the chuck housing, you can flip the inner chuck one way for shanks and the other way for tubes. Another surprising feature is this Tube Chuck, which clamps down evenly around the circumference of the tube (only holds Large 1/8 OD tubes such as HMH Rigid Tubes) and does not crush or mar the tube body. Once clamped into the chuck the tube does not spin out of place, even as the tyer makes consecutive outward pulling thread wraps. We were a little apprehensive at the cost of such a tool but can say the chuck is surprisingly secure and extremely easy to adjust. It’s a brainless tool. And yes, the chuck tool secures into any vise you clamp it into.

The chuck will hold shanks down to OPST Micro Shanks, which are 0.90mm in diameter. Tube adapter inner diameter: 2mm.
