I can highly recommend Eric at On-Scene Tactical<br>http://www.mnsi.net/~nbtnoel/<br>His reputation for Kydex sheath work is terrific. Follow some of the threads in Blade Forums, etc. I think he may even have some "ready to go" sheaths for the Cold Steel series.<br><br>You might want to consider having the sheath configured with a Tec-loc belt attachment system. For the slight increase in cost, you get a lot of attachment choices. If you really anticipate being tumbled around, you might ask Eric about "jump certified" sheath systems... or a secondary fastener in addition to the fit of the Kydex.
