Thanks you all for the warm welcome and the advice. I'm leaning towards kydex for my Ratmandu, but a SPEC OPS survival sheath would also fit my needs nicely. Speaking of SPEC OPS, i may also need to pick up one of their belts, mine also roll and sag under the weight of my Ontario RTAK-II. Anyway At Blade West I talked to Brian Wagner, the guy behind Okuden knives and sheaths (wonderful fellow, very knowledgeable) and he apparently has a Ratmandu on loan from Swamp Rat for use as a template for sheath making. I was super impressed with his products and may order from him. Oh, one last question. I seem to recall that the ever-helpful Andy Wayne (I think it was him) made a thread to explain how to post pictures. I looked for it, but never found it. Anyone have the link? Thanks.
