I have only seen it from the photos on the net, the blade end has a screw but I have seen what seems to be a rivet at the bottle opener end. Is the tool held together with alan or secure 6 point torx screw? Have you tried a 1/8 to a 1/4 turn to try and free it up a bit or is it the components themselves that appear to be grinding? My curiosity about this tool is killing me I just wish they would get some over here for sale.
