I started to wonder about any glues too. Mine is wood handle, and not sure if anything to worry. Was in about 30 minutes including preheat. Was late at night, so didn't do 3 hours. At camp so gone during days.
The sheath is tight now, and want to carry. The wet molding didn't take much shape. Seems like thick leather.
Might also pick up a small bark river******edit been reading lots of stuff on here. Googled Mike Stewart, should be added to the discussions he is not a Yooper, he is from Philadelphia.
