Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Seamless robe of Jesus
According to the Gospel of John, the soldiers who crucified Jesus did not divide his tunic after crucifying him, but cast lots to determine who would keep it because it was woven in one piece, without seam. A distinction is made in the New Testament Greek between the 
"himatia" (literally “over-garments”) and the seamless robe, which is "chiton", (literally "tunic" or "coat").
