1881 Knifeworks knives
1881 Knifeworks makes fixed-blade knives through its Phoenix, Arizona workshop, where the company says it designs, machines, heat-treats and assembles its knives. Many models use 1095CV steel and G10 handles, though specifications vary. The brand’s range includes compact carry designs as well as larger outdoor and field knives.
The San is a shorter fixed blade described for fieldcraft, while the AIO-2 adds features for lashing and striking. The Jungle Fighter has a longer blade and a dual grind, and the Romulus takes a distinct double-edge dagger form. These models help illustrate the range’s different sizes and designs.
Models for different tasks
The San is a compact fixed blade with a 4-inch blade and 8.7-inch overall length. Its full-tang construction means the steel extends through the handle, and the maker describes it for fieldcraft and carry. A fire-starting divot is built into the design. The AIO-2 is larger, with a 5.3-inch blade and 11.3-inch overall length. Its blade has dull notches for securing cord, while a grooved pommel is intended for striking. The Jungle Fighter has a 5.8-inch blade and a dual grind, meaning the blade uses two different grind profiles. Its deep choils provide grip positions for varied cutting tasks. The Romulus is a substantially longer, double-edge design with a 9.5-inch blade; its form draws on the Roman gladius. Each model is supplied with a leather sheath, with details depending on the model.
Materials and construction
The San, AIO-2, Jungle Fighter and Romulus specifications list 1095CV steel and G10 handles. G10 is a layered composite handle material. Handle color options include black and OD green on selected models. The San is described as full tang; avoid assuming a particular construction or identical features across the whole range, as designs differ. The AIO-2’s 2024 reissue has updated geometry, and its blade is not serrated. These are fixed-blade knives, so choosing between them mainly comes down to blade size, shape, grip details and intended task.
