A welder's protective helmet is provided with a detachable face mask with a handle which allows the welder to detach the same, as desired, and hold the face mask in front of his/her eyes during welding but to easily and quickly move the same to the side for direct viewing. The handle can be provided with a forwardly directed V-shaped trough for holding the extension of the welding torch so that welding proceeds while the user's eyes are protected since the user's hand is holding both the welding torch in the trough of the handle which is also holding the face mask.

An implantable spinal graft includes a substantially annular body with opposed superior and inferior surfaces. At least a portion of the superior and inferior surfaces includes a plurality of bone-engaging protrusions. Both of the superior and inferior surfaces also include at least one region that is free of protrusions. Preferably, the protrusion-free regions are centrally disposed and are oriented so as to be parallel to or angled with respect to an anterior-posterior axis of the implant. The implant further includes a tip on the posterior that is formed by converging portion of the superior and inferior surfaces.
