Like many others, I have just received the replacement sheath for the NorthStar. I don't much care for lite colored sheaths and because I'm likely to wear the knife during wet conditions, I also wanted to protect the leather from the elements. I did some seaching and on the BRKT forum, I got the tip to use Sno-seal. It is a natural bees wax product that waterproofs, but will also darken the leather as a side effect. Using the instructions on the package, I heated the sheath, warming the leather to an easy to handle temperature, so that it would melt the sno-seal and speed up the process of the leather soaking the product up. After heating and applying the product two times, this is the results.
