Why not vert carry ? You know what works for me is a gerber small soft sheath, I think it came with a mp400 but the older ones. It lays really flat, about as flat as you can get. Just a thought.
Just ordered these...http://www.ebay.com/itm/Lot-3-Sheath-SH279-4-Knife-Pouch-Will-Fit-Most-Folding-Knives-P-To-4-Closed-Bl-/380834779551?I don't like Velcro, but couldn't beat the price. Will see if these are acceptable for SAKs.
Nice. I'll be sticking to my modded Maxpediton. Hope it serves you well. What else do you plan on putting in it?
