kydex sheats... I make them by myself.
I have made 8 ( for eight different knives) till now. 3 for scraps, 3 for busses, 2 for 2 different type of Nexus

The knife with the toilet paper is a Nexus Caio, a semi-custom knife made in 80pcs. ( 160 J toughness..... )

" Mess with the best, die like the rest " .... If I'm not wrong, is an USMC motto :-)
I know I'm italian, but I like it !!
