I was wondering what folk are using these days to water/weatherproof their sheaths. I have a couple nice Barkies that are my primary carries when I'm in the woods, which is nearly all the time. I live in wet, humid Nova Scotia and want to make the leather sheaths they come with, which are very nice, more resistant to holding water. Any new materials out that are recommended? I know this topic has been addressed now and then, but the most recent post I've found on it dates back to 2007.
