There are options.
1. Send it to CRK for silver parts. Plan on spending some money and waiting a month or more.
2. Buy a new knife with silfer parts (certain dealers have these available). You know the cost involved with that.
3. Modify your own parts to make them silver. Fairly easy, and cheap if you already have the stuff you need.
4. just use it and the color will fade on the thumb stud, remove the lanyard pin and tie a lanyard through the holes, and put an o-ring or strip of colored tape on the backspacer to make it any color you like.
