Eric, who made the sheath has a Chris Janowsky RANGER I sent him. The blade on that dedicated survival knife is a nominal 2.5" and skins and butchers very well.
Readers should remember Oetzi, the italian alps ice mummy carried a hafted flint blade of equally small dimensions.

And now, with embaressment, I put my new light through a rather ignoble torture test. My old BCB tin PSK somehow managed to find it's way INTO a supersize , fastfood coke. I suspect a family member with a disdain for the outdoors.And there it sat, under a patio chair for 5 days until I started putting together my daypack for a field survey and discovered it just today.

Well,The tape was a gooey mess and the tin rusted with pinholes.My high carbon, small scandinavian blade is a disaster, the edge now serrated. My aluminum SPARKLITE worked after flushing in clear water.But needles, BCB commando saw, mirror--well it was all a fused,rusted and coagulated mess until I pulled out the new light. It required rinsing, but looked unscathed. And then I twisted the head and 'THUS SPRACHT ZARATHUSTRA' there was light!
It's a winner.
