As posted here... http://bonsainut.com/forums/showthread.php?9218-Another-Boxwood-I-am-working-on&highlight=boxwood Not impressive looking tool but works well. I just used a cheap diamond cut off bit (I bought for a dollar a piece or so) and Dremel to chop this box wrench. Honestly, I am actually surprised it went through this. This particular tool can bend up to 1" diameter branch...limited only by the opening but you can make one out of a bigger box wrench. They come very cheap at garage sales or flea markets nowadays. I usually wrap electrical tape on the branch first then add padding (piece of old hose cut off or thick leather in 2 contact points) after the wrench is in position before bending. If you wrap with raffia with embedded wires, that will change the outside diameter so just make sure it still fits the tool opening. I plan on changing it a bit later and grind some curve at the top and bottom to fit the branch being bent better....also to make sure the "teeth" to hold nuts won't cut the bark/wood when bending. For now I just use leather or old hose as cushion when bending. I have plans on "re-purposing" another item to bend even bigger branches. We will see how that goes and I'll report once it is tried.
