Confused – Case Clicker Review

I just got the game and it seems like a slow start but fun long term game. Anyways, I’m wondering since my first case opened I got a Damascus steel gut knife and it was worth about $63 and I was so excited and I pressed lock to see what it would do but now it is literally just gone. I didn’t get the money for it and it isn’t in my inventory any recommendations?
