FB09 Ronin

"What is a Ronin? Translated literally it means "wave man". Rendered understandable to the western world, it's an ancient masterless Samurai warrior. In the knife world the Ronin is a fixed-blade neck knife designed by Michael Janich. Mike Janich took the design to custom knife maker Michael Snody who for several years made and sold a custom version. The Ronin is Spyderco's production version.

By virtue of its short blade length it is lawfully acceptable for carry most anywhere. The blade has a modified Wharncliffe-shape and is crafted of VG-10 stainless steel. Available PlainEdged, the cutting surface is flat-ground, honed thin and fiercely sharp. Made from an imposing 3mm thick slab of steel, the blade comes pressed between two pieces of slate-colored linen Micarta. Texturing along the spine provides a location to place the thumb and offers extra gripping ability when choking up on the blade. On the bottom side of the handle a yawning index finger choil situates the hand for quick retrieval and responsive control while cutting. Three dime-sized holes drilled out of the handle knock out a few grams of weight and provide indexing. Gripped in the hand, the stout little blade and curved handle feel rock solid, goading you to put it to hard-use. The Ronin is now accompanied by a Boltaron belt sheath - Sorry we are all sold out of neck sheaths and will only be producing the belt sheath. Please note the pictured sheath is the neck sheath - sorry for any inconvenience." [1]

FB09G2 Ronin 2

"A direct descendant of Michael Janich’s original Ronin™ design and close cousin of the Yojimbo™ 2 folding knife, the Ronin 2 is based on a custom knife Janich commissioned from knifemaker Mickey Yurco. Its blade is crafted from Carpenter® CTS® BD1—a vacuum-melted stainless steel that is highly corrosion resistant and holds an excellent edge. Deep hollow-ground bevels on each side of the wharncliffe blade define a perfectly straight cutting edge, enabling it to cut with full power all the way to the point while leaving its spine thick and strong.

To ensure maximum strength and a deft balance, the Ronin 2 features a skeletonized full tang capped by thin textured black G-10 scales that guarantee a positive grip while allowing the knife to be easily carried and concealed. At the junction of the handle and blade, the tapered, ergonomic profile of the handle flares to create a very effective integral guard that protects the user’s hand from sliding forward onto the edge.

For maximum versatility, the Ronin 2 comes equipped with a custom-molded Boltaron® sheath and a G-Clip™ attachment that supports both belt carry and clip-style inside-the-waistband carry. The G-Clip is also configurable for vertical, horizontal, or diagonally canted carry and can be attached to both faces of the symmetrical sheath." [2]
