Mcusta manufactures precision folding knives in Seki, Japan, a center of cutlery production since the 13th century. Established in 2000 by Marusho Industry, Inc., Mcusta combines traditional Japanese craftsmanship with modern CNC machining and laser-cutting technology. Each component is laser cut instead of die stamped, then hand assembled and finished by experienced craftsmen. The name Mcusta stands for "Machine Custom Knives," reflecting their semi-custom production approach that delivers hand-finished quality at production knife prices.
VG-10 and SPG-2 Blade Steel Construction
Mcusta primarily uses two Japanese steels in their blades. VG-10 stainless steel has a core hardness of 59-60 HRC with excellent edge retention and corrosion resistance, used in their Classic Wave, Katana, and Sengoku series. SPG-2 powdered high-speed tool steel offers higher hardness at 61-62 HRC for superior edge retention in their Shinra Maxima and Tactility Elite models. Most blades use San Mai construction, a three-layer laminate with the core steel between softer outer layers for added toughness. Damascus versions add 33 layers of nickel steel for distinctive patterns while maintaining the core steel's performance.
Linerlock and Framelock Mechanisms
Mcusta folding knives use stainless steel linerlock construction for secure blade lockup across their product lines. The exposed liners support the handle scales, and the lock bar engages the blade tang for reliable operation. Shinra and Nami series models feature framelock designs where the handle serves as the locking mechanism. Both systems use Teflon washers for smooth blade deployment with dual thumb studs. Pocket clips are reversible for tip-up carry in right or left-handed configurations.
Handle Materials and Traditional Design Elements
Handle construction varies by series but emphasizes natural materials and refined aesthetics. Pakkawood, a laminated wood composite, appears often in the Sengoku and Shinra lines, offering durability and moisture resistance. Canvas Micarta provides texture and grip in the Tactility and Petit series. Some models feature ironwood, African ebony, or Damascus steel handle scales. The Katana series uses forged, double-anodized aluminum in contrasting colors. Many handles have laser-engraved traditional Japanese motifs such as bamboo patterns, wave designs, and samurai-inspired elements that reference Seki's sword-making heritage.
Popular Mcusta Series and Models
The Katana series draws inspiration from traditional Japanese swords with tanto blade profiles and wrapped-look aluminum handles. Shinra models feature mountain-inspired aesthetics with bamboo motifs and hammered finishes. The Tactility Elite line offers larger blade profiles with ergonomic contours for tactical use.
