It seems that the shop could not have set the snap if they did not get the knife into the sheath.

Maybe...it could be put up for sale here on the forum, and one of us will be quick enough to pick it up.

P.S.: The thickness of the guard can meet resistance against the sheath as the knife is pushed down into place. Hence DW's suggestion to bend the sheath back to make it flex at the throat. The sheaths are stiff and can take some "wearing in."
