I'm trying to decide on something also for my (coming soon) Desert DF.
LOVE the looks of that beauty HD got from Rainmaker - very nice features and detail! Something like that w/out the tooling and oil up good for outdoor use would be nice.
If I'm going to wear it I don't like them riding up high so prefer the low rider, dangler, drop down styles with leg tie-down capability. I do like the leather Randall/Johnson model C style sheaths.
Not a huge fan of Corudura or nylon type sheaths so far. Have on for my Rat-7 and it is flimsy for drawing / reholstering. However it is light weight which is great for hiking. Something to consider if trekking with a big fatty. Maybe the SY version is better.
If strapping it to a pack, which I sometimes do with a small (12") machete, then open top Kydex I find works well. What do you guys think of the stock DF kydex offered here?
