This is the famous Sword Through Neck illusion, constructed in a necktie. As a result you have a sword apparently going through the bare neck without any shielding by a "frame" or "stock". The sword is pushed right through the assistant's neck and it visibly emerges at the opposite end. It is then pulled out again to show the assistant is perfectly unharmed. Comes complete with special tie that makes this possible, and stainless steel sword and scabbard.
