How to Sharpen Crucible Dividers

Posted on 27 November 2016

Sharpen Crucible Dividers from Christopher Schwarz on Vimeo.

A few customers have commented that their dividers have slightly irregular tips or have difficulty making clean holes in hardwoods. After some back-and-forth with the customers, we realized that they hadn’t sharpened them.

Like a plane iron or a chisel, the final edge shape is up to the customer. Some woodworkers like a needle point. Others like more of a triangular tip. And those who do marquetry will sharpen one leg of the tool with a chisel tip for cutting veneer.

Sharpening your dividers takes less than a minute and can be done on a flat surface with a piece of sandpaper (such as #320 grit). The newly sharpened tips will last for an incredibly long time (perhaps years if you don’t damage them).

On Saturday I shot this short video at the Crucible lab of Raney sharpening a pair of dividers.

Move videos on the dividers are in the works. Stay tuned.

    You might have gotten one of the pairs we were tuning up and testing. In any case, now you know how to sharpen them for the next presidential administration.

    I picked up a set on launch night; I’m wondering if I got one of your personal pair thrown into a box by mistake? Mine were quite sharp out of the box and it never occurred to me that more finesse was needed.

    Regardless, I’m still using the snot out of them.
