Very nice blade, my first EDC was an Endura, these two obviously light years ahead of that one in every way.

The final thoughts comment on a review I found were funny:

This knife is not for the weak or faint of heart. It is a hefty 6.2 ounces, so if you are not a strong swimmer, then I do not recommend that you jump into the water with this knife in your pocket, even though it is stainless steel.

These two are not just a Vallotton sub hilt, and a mini Vallotton though. They have both been converted to dual fire.

That means you can open and close it normally, and fire it auto by moving the sliding bit of scale with your right thumb.
