This past Sunday my wife bought me a new Tops Scout fixed blade knife. I love it, but the knife is very hard to pull from the sheath. It is made out of hard plastic, and the knife snaps into place when pushed into the sheath. Will it loosen up after a while or is there something I can do to make the knife easier remove from the sheath? It concerns me because it takes two hands and a decent amount of force to pull the knife. Not to mention the risk of me or someone else getting sliced.
