Notice the holes...(for the record this has to have been discussed before?, right?)...There are Three different size holes, small, medium, large on the tool itself. In order to get the holes to match the exact position as the real helmet you have the Cut the borden tool on the back side, and then turn it around....thing about that is, you will find, as previously mentioned, once cut all the current borden tools are now made of Brass and silver plated. :facepalm
Yeah... I think we have mentioned it a time or two... but it usually gets buried.
Not only do you have to cut and flip it but you have to very very carefully bevel all those tiny holes and the edge of the cylinder. What a pain!!!
