The ergonomic shape of the ‘Black’ is the same as the ‘Wood‘ and ‘Deluxe‘ versions and its key feature is that the body is made entirely of the engineering polymer Delrin. Delrin is more dense that wood and will wear at least as well, if not better, than wood.
This version is in regular use, for shaping seats, by myself and my students in The Windsor Workshop. It is warm in the hand, has a satisfying weight and the black material leaves no marks on the wood being shaped.
In addition to the features mentioned above, the body is almost indestructible and is completely unaffected by water, which is a bonus for chair makers working outdoors!
I strongly recommend this tool. However, if you prefer the look and feel of wood then consider the ‘Wood‘ version and if you want a premium tool that looks superb and will never wear out, under normal use, then try the ‘Deluxe‘.
