About to place an order there myself for a few more Mora's. Good thing about RK is they state on their website that they will make anything if you are willing to send your knife to them. I might just do that for a few Skallywag daggers.
I got an Esee 3 and Spyderco Street Beat covered from Armatus Carry but RK is priced better if you have multiple sheaths on different gear or daily carry in mind for a single blade. I do like the ergonomics of Armatus but it's not necessary on everything for me.
