Got a great blade that rides in a shameful sheath? I used to, but I've recently had success with Bob Schrap of Wauwatosa, WI. Long story short, I recommend him to the forum.
I decided to have a sheath made for a large, unusually shaped blade. After a little poking around I sent my blade off to Bob Schrap, who just returned the package to me (approx. 6 week turnaround). He made this beautiful leather sheath for me for about $80. Keep in mind this costs more than most of his sheaths (usually ~$60) because I am picky and wanted specific features, including Kydex liners, tie-down points, ostrich-leather overlay, and a loop for a firesteel. I have little doubt that this sheath will outlast me.
