Hi, Sing! You may be interested at taking a look at my website. I do some sheaths on the side mainly for fellow BFC'ers. There was a review of one of my sheaths in the main forum a few weeks ago and another currently in the Good, Bad, Ugly forum.
I just finished making a concealment sheath for a Polkowski Polecat that has two clips, one for IWB carry and the other for small of back (in several different configurations) and crossdraw.
You can see my information page below. Just click on the Kydex section, and there are also pictures of most of my sheaths that you can see, including the Polkowski one. Most of my sheaths run in the $35 give-or-take a few dollar range, and I require the knife for fitting. You can link to the two BFC reviews of my work, too, at the webpage. let me know if I can be of assistance to you!
