Thanks for your thoughts gents.

I have actually made sheaths before - but they tend to be agricultural, functional type things, I'm more the engineer than the artist.

In the absence of better info I guess I'll get an S6 nylon and see how it goes.

I'll probably get an S6 First Position Kydex too probably, and it if does not go OK - well I can always put my S6 in it.

If either go well then I guess I'll go back and get the necessary extras with a second order.

Getting something custom made up is an expensive proposition down here (Australia) there's a dearth of sheath makers that I can find, that do the sorts of sheaths I like.
And postage adds up, especially if you have to send the knife to the US to have it fitted.

And I'm the impatient type!
Gen X. Instant gratification please.
;-)
And any way once I get my hands on a knife I am loath to give it up.
Completely irrational but then again so is a collection of serious knives for a city dwelling computer geek who gets out bush, at best a couple of times a year!
