Been doing a bit more leather work the last few days. I made this horizontal carry sheath for my CRKT Fire Spark folder. Water formed, Blade Tech mini tek-lok snap lock, and an integral fire steel carry. The open end sits on my right hip (I'm right handed). The sheath is tight enough that there are no issues with needing a retention strap. I can hold the sheath upside down and shake it hard and the knife does not even move.
