SPYDERCO是个创立于美国科罗拉多州的刀具公司，它以前所未有的创新精神而闻名。现代名牌折刀中的单手开启功能、便于携带的卡子(CLIP)这些几乎成为现代高科技折刀标志的设计。正是SPYDERCO发明的！如今不断创新的SPYDERCO公司已拥有数十项设计专利。其商标性的单手开启园孔造型不仅是最快捷顺畅的开启方式，而且这种独特的造型使人们一瞥之下就能认出那是SPYDERCO的产品。开启最为迅捷！SPYDERCO另一独特设计专利是SPYDERCO锯齿，这一发明是受到了鲨鱼牙齿的启发，SPYDERCO是不仅在业界最先成功使用锯齿刀！而且其与众不同的设计使之比普通的锯齿刃具有更强的切割力和更长的保持能力，它的切割力足以割开Kevlar-凯芙拉材料的防割手套！SPYDERCO另一强大优势就是它选用的钢材，它们从不用那些低成本、低性能的420或425系列的钢材。而它选用的钢材有AUS系列、ATS系列、440系列以及VG系列，甚至制刀界中的顶极材料CPM440V都是它们的常用材料。在美国Spyderco被称为“标准创立者（Standard Setter）”创新的设计，精良的选材，完美的工艺。

Kumo is Japanese for spider and a fitting name for the new Japanese influenced fixed blade knife designed by custom knifemaker R.J. Martin and manufactured by Spyderco. A self-professed steel junkie, R.J. Martin is celebrated for integrating multiple grind lines on the blades of his knife designs. Made from a solid 9-inch piece of VG-10 steel, the Kumo blade has two definite grinds: a swedge-grind along the spine and a hollow-grind above the non-serrated cutting edge. Converging in the center of the blade the two grind lines meet creating a look that is streamlined and pleasingly tapered. Where the thumb naturally settles on the blade are a series of notches that latch onto the thumb pad adding an appreciative level of grip and cutting control. In Japanese fashion, the handle is wrapped with epoxy-saturated cord over an undercoat of pebbly black stingray skin that has a silver Spyderco bug Menuki peeking through the wrapping. The Kumo slips into in a fitted black Kydex sheath mounted with a TekLok® detachable polymer clip that can be situated to carry the knife in five different carry positions: vertical, inverted, cross-draw, small of back or horizontal position. Overall length of the Kumo is 8-5/16” (211mm) it’s PlainEdge cutting edge is 3-3/4” (95mm) and it weighs 3 oz (85g).
