Made 1910 - a hundred years old.
These knives were made from around 1850.
Carved of Birch, edged in steel, neatly trimmed internally to house a brass and steel knife, which was held in the sleeve by a spring clip. It was held to the belt on the ring attachment. After the knife was slid out and cocked 180 degrees, it was replaced in the sleeve, and clipped. Very popular with seamen. This one owned by my great grandfather, on the Isles of Scilly. The date is known from the manufacturer's name.
A Swedish Barrel Knife. Very collectible.
