3LegDog is the maker mark of Riaan Manser, a full time knifemaker working out of South Africa. The name honors Patch, the three legged shop dog who kept him company from 2007 until 2018. Manser built fixed blades through 2014 before turning to folders, went full time in 2016, and came up in the orbit of Andre Thorburn, Trevor Burger, and George Muller, which is about as good a lineage as the South African folder scene offers.
Most of the line runs RWL34, a powder stainless that Damasteel developed to Bob Loveless's specification. Composition sits close to 154CM, but the powder process gives it a finer, more even carbide structure, which is why it takes a mirror polish that conventional 154CM will not and why custom folder makers have leaned on it for two decades. Run at around 60 HRC it holds a working edge well and sharpens without a fight. The G8 models go the other direction with CPM MagnaCut, trading a little of that polish for the corrosion resistance and toughness balance that has made it the default premium choice. More on how both compare in the steel comparison guide.
The G8 is the compact one, a 3.5 inch harpoon or drop point on a 7.875 inch overall frame at 4.27 ounces, offered as both a standard flipper and a front flipper. The W5 stretches to a 3.625 inch harpoon on an 8.25 inch frame and the W5 Midi splits the difference for anyone who finds the full size a bit much in pocket. The H4 is the largest at 8.5 inches overall. Every one of them runs a liner lock, 4mm blade stock, and a right hand tip up clip.
Manser works black G-10 as the base frame and insets contrasting panels of ironwood, linen micarta, tan G-10, and purple accents, which is where the fit and finish shows. The H4 and one W5 Midi build go full titanium instead, adding weight and stiffness. Our handle materials guide covers how those choices behave over time.
