Although I love the leather sheaths, considering you want to have the sheath canted on your belt, perhaps the kydex is a better choce for you.

Here are some pics of the kydex sheaths.

As the above pic shows, you can adjust the clip piece by attaching it to the sheath through a number of holes, thereby changing it from vertical, horizontal, or canted.

Personally, I like to carry the S6 inside of my waist band, like so. Just something I've gotten used to with that particular knife.

As you can see, the HCLE and DMLE sheaths are both canted, if a little crowded, being on my belt so close together! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

As you can see from the pic, there is a bit of difference between the S6 and the SOD.

If I were going to get the leather X-loop for the SOD, I'd suggest the same as what Jeff has mentioned; get it done with two X-loops on the back, so as to center it on the back of your belt, and avoiding that center belt loop on the back of your jeans.
