The firesteel loop on sheaths from Bark River Knives accommodates a 3/8" firesteel. The following firesteels will fit the Bark River loop:
- Bark River Custom Firesteels
- KnivesShipFree Custom Firesteels
- LightMyFire Swedish Army Firesteel
- KnivesShipFree 3/8" Misch Metal Firesteels
The leather loop is designed to hold a firesteel snugly, so inserting it the first time may take a little effort. If you have trouble, insert a pencil or similar object into the upper end of the loop, work it around a bit, and then try the firesteel again. It'll get easier the more you use it.
