Thanks Denis (& Nursemike too). I thought I was *supposed* to tie it down, and as you figured that's what I thought your paracord wrap was for. Now that you mention it, I recall the holes were in fact described for use as a neck knife, probably by Paul. D'oh!
Previously I only brought an Endura folder (my EDC, shortly to be changed) and a hatchet with me. No sheath knife. You probably know that the Endura is around the same size, and I find it comfortable to manipulate...that's the first thing that told me I'd like the F1, and having more handle meat + metal in there for balance made it an obvious good choice for me. I also like VG10, not too fancy for my sharpening "skills", and a decent hard-working steel IME. (That's what I meant by not copying you blindly.)
