This is a sycamore wood handle intended to replace the very plain handles that come on most glass tools (marvers, shapers, molds, etc.). Each one is individually hand-turned by me in my woodturning studio, and is thus a one-of-a-kind item. It comes with a pre-drilled hole the size of the bolt in most glass tools, so it's easy to just cut the bolt with a hacksaw and install it. However, if you're not handy or aren't sure about doing this yourself, you can mail me the tool and I will install it and mail it back to you ready to use, at no extra charge.
Many people find these handles more comfortable to use than the originals. They also make it easier to quickly locate the tool on a crowded work surface, since it will be the only one of its kind. A brass ferrule reinforces the tool where the bolt is inserted.
This handle measures 6" long and approximately 3/4" diameter.
