I'm missing the short part of the (I think it's called) pivot screw on my knife, and looked everywhere to get a new one to no avail. I honestly have no idea how I lost it either. It probably happened 1+ years ago and lately I've been thinking about it more and more, so I'd actually like to replace the piece (I think other than that 1 piece is still in fine shape, just needs to be sharpened). Anyone know where to get these specific replacement pieces, and are they inexpensive? Thanks.
