I posted a picture a couple of weeks ago of a Becker BK7 fixed blade knife I recently bought. I contacted Grizzly Outdoors about making me a custom kydex sheath for the knife.
I received my sheath and am very pleased with it. If you are in the market for a durable, well made knife sheath, check this website out.
http://www.grizzly-outdoors.com/The business is family owned and they craft all of their sheaths by hand here in the USA. I just ordered another sheath for the BK14 that I ordered as a companion to the larger BK7. He does a variety of mounting options for the sheaths and has numerous colors of the sturdy Kydex material to choose from. He definitely gets 2 thumbs up in my book!
