Geez, ya buncha nancy-boys. You don't need any tools (unless you really want them), and you don't need to smoke the cigar backwards.
To create a cigar, the roller grabs a bunch of filler tobacco, bunches it together, and wraps binder leaf around it to hold it together. It then goes into a press for a time to help it hold its shape. Then they cut end of the cigar off while still in the mold to trim it to size, take it out, and apply the wrapper leaf to the cigar, from the foot to the head, wrapped over itself.
At this stage the cigar is open on both ends. The head is trimmed, and a bit of leaf is applied on the top of the cigar, called the "cap". Which is literally what it is. Pick the cap off, and you're ready to smoke.
The cap is all that stands between you and getting a draw from any properly constructed cigar (perfectos/torpedos excluded of course).
