Maybe He Fell In

Lynvarr leaned the spear against a larger rock and then moved to his travois to get his pine pitch.
Taking it in his jaws he trotted over to the fire to warm it til it became sticky and soft enough to fill the notch. He took the pine pitch back over to the end of the spear and lightly pressed the pine pitch into the notch. He then carefully pressed the back end of the spearhead into the notch, using one of his paws to hold the spear steady. Lynvarr held the spearhead into the spear notch until the pine pitch dried enough so that the spearhead wouldn't move out of place.

He sensed the sorrow in the other man's voice and so he did not press the conversation any further. Lynvarr moved back to the pine pitch, heating it up a bit more before applying it to the notch in the axe handle. When that was good and sticky he pulled a bone axe blade from his travois and settled it into the pitch-filled notch until that dried and hardened as well.
