    I have no idea of a particular use. I also don't know why a caliper would need such a long handle.... to reach inside a tight space for the particular measurement?

    I have something like that. Its used on a wood lathe to cut to a
    specific depth:

    I was thinking reaching up, like to measure a branch or something.

    At first I thought "lathe" also, but I couldn't think of a lathe related reason reason for the long handle.

    May not be that it measures wood, but that long handle is definitely
    wood.

    I have no idea as to its purpose.

    One never knows - it could just be his best guess,

    My guess is a wood lathe tool designed to cut to a certain diameter. The short cutter tool clamped at the end of the tool underneath the arch appears to be a cutoff blade from a diamond parting tool. Parting tools, and diamond shaped parting tools, are
    designed to cut wood on the lathe by pushing straight into the wood and scraping/cutting down to a certain diameter. So the end of the arch to the tip is the diameter that is cut. The lower blade is movable and clamped by the turn bolt on top. I'm
    guessing the tool was assembled from various other parts for cutting to a uniform diameter. Someone found the arch top piece. I'm not sure what it is for. Then cut the blade off a parting tool. Then found a turn bolt and made a spring clamp and put
    it underneath the arch piece. And then because its a woodturning tool, they made their own handle and stuck the whole contraption into the wood handle. You can easily see the tool is not straight into the handle. The metal part of the tool is
    rectangular. Not round. So they just monkeyed around and got a slot cut into their wood handle and pounded it in.

    If you were in a factory making wood handles that needed to be 1 inch diameter. For the preformed metal collet to fit over the wood. You would set this tool to 1 inch and then just go to town by pushing it down over the top of all the pieces you put
    onto the lathe. No measuring or guesswork involved.

    The question here is: Why the extra long handle? The turner typically stands right at the lathe
    and the work piece is at arm's length. Why would an extension handle be needed? Seems like
    it would be more cumbersome to use than the "normal" method, shown below:

    Not knowing exactly what this is, a turning tool for turning an exact
    diameter and or thickness looks like this. Why the long handle
    leverage for reaching inside deep vessels. But I'm not certain how that
    would work with this tool. But long handles are pretty common for
    turning tools. I suspect this is for making exact diameter spindles/ends.

    Yes, the turning tools themselves are often long, but I think that is for >leverage and control.

    I can't think of a reason why a turner would want to be so far from the >workpiece when checking it. An image search for calipers always show
    the more familiar up close and personal style.

    https://www.google.com/search?q=calipers+for+lathe&tbm=isch

    The small size of the calipers combined with the long reach of the
    extension just don't seem to go together. A puzzler indeed.

    My guess is a wood lathe tool designed to cut to a certain diameter. The short cutter tool clamped at the end of the tool underneath the arch appears to be a cutoff blade from a diamond parting tool. Parting tools, and diamond shaped parting tools,
    are designed to cut wood on the lathe by pushing straight into the wood and scraping/cutting down to a certain diameter. So the end of the arch to the tip is the diameter that is cut. The lower blade is movable and clamped by the turn bolt on top. I'm
    guessing the tool was assembled from various other parts for cutting to a uniform diameter. Someone found the arch top piece. I'm not sure what it is for. Then cut the blade off a parting tool. Then found a turn bolt and made a spring clamp and put it
    underneath the arch piece. And then because its a woodturning tool, they made their own handle and stuck the whole contraption into the wood handle. You can easily see the tool is not straight into the handle. The metal part of the tool is rectangular.
    Not round. So they just monkeyed around and got a slot cut into their wood handle and pounded it in.

    If you were in a factory making wood handles that needed to be 1 inch diameter. For the preformed metal collet to fit over the wood. You would set this tool to 1 inch and then just go to town by pushing it down over the top of all the pieces you put
    onto the lathe. No measuring or guesswork involved.

    I'm sure that most of us are familiar with the use of calipers for determine the diameter of a
    turned object. Even if we (I) don't turn, we (I) have seen it done, understand the process, etc.

    The question here is: Why the extra long handle? The turner typically stands right at the lathe
    and the work piece is at arm's length. Why would an extension handle be needed? Seems like
    it would be more cumbersome to use than the "normal" method, shown below:

    Not knowing exactly what this is, a turning tool for turning an exact diameter and or thickness looks like this. Why the long handle
    leverage for reaching inside deep vessels. But I'm not certain how that would work with this tool. But long handles are pretty common for
    turning tools. I suspect this is for making exact diameter spindles/ends.

    Yes, the turning tools themselves are often long, but I think that is for leverage and control.

    I can't think of a reason why a turner would want to be so far from the workpiece when checking it. An image search for calipers always show
    the more familiar up close and personal style.

    The small size of the calipers combined with the long reach of the
    extension just don't seem to go together. A puzzler indeed.

    It's not for checking, it's for *sizing*. This is a cutting tool, not a measuring tool. You want that long handle for leverage. Today's
    lathes, you can get by with a shorter handle because higher RPMs mean
    shallower cuts, but on older slower lathes you'd need the longer handle
    to fight against catches and digs.

    This kind of tool is used to quickly and accurately cut tenons, or to do
    a final pass to get a "perfect" diameter.

    I was looking for the item you posted before I made my reply. But could not find it on any woodturning tool sites. I thought I had seen something like it but memory was not great. I had no idea Sorby was the one who made it. Just an idea I have seen
    something like that before. I was thinking the Sorby tool went over a parting tool. But no. A bedan is used. A wider parting tool more or less. Looks like this tool starting this thread was made before Sorby came out with their ready made tool.
    Someone had an idea of what they wanted. A very common idea many people had thought of before. And they made something to work for their immediate job at hand.

    As for all the comments on the extra long handle. I suspect it was more a matter of what was available as opposed to design. Someone made, cobbled together the metal part of this tool. By cutting, welding, scrounging, drilling, bending. And they were
    left with that long thin rectangular handle on the metal item. And that was not safe or easy to hold with a spinning lathe. So they looked over at the scrap bin and saw a long wood handle from another tool laying on the bench or leaning in the corner.
    Gathering cobwebs. And they thought, perfect handle, or good enough. Grabbed the old handle and drilled and chiseled an opening in the end to fit their rectangular metal contraption. And they ended up with a good enough working tool for them.

    And now years later someone thinks its valuable and is trying to auction it off.

    Precisely. And as the video shows the handle is tucked between the
    users arm and the side of his body, hence the long handle.
