Spyderco has several knife designs that remain steadfast year after year. What keeps people buying them over decades is their basic function but also that they’re upgraded or refreshed with new technology and materials when they become available. A prolific design in Spyderco’s line is the Calypso. Its arrival over a decade ago as a mid-sized folder has spawned numerous variations and converted legions of knife buyers to the benefits of flat-ground, thick leaf-shaped blades. This is a workingman’s or woman’s folder founded on the premise that a comfortable, usable pocketknife is one that feels like a natural extension of your hand. A larger, newer Bionic version of the original Calypso Jr. is the Caly3.5. The latest Calypso progeny has a three and a half inch VG-10 leaf-shaped blade that is thick at the tang, then tapering to a tip. The cutting edge is flat-ground and thin for precision and receptive cutting. Ergonomics and control were taken into the designs’ consideration and where handle and blade meet is a substantial finger choil. This is the spot where the index finger settles ergonomically leading the thumb to naturally position itself directly above on the blade’s spine. Also the spine is textured with slip resistant jimping making the knife feels like part of the hand with no sliding forward or backward while cutting. The black G-10 handle has a mid-positioned back lock and a low profile wire clip, holding the folder deeply in a pocket facing tip-up.

Knives are one of the oldest tools to ever have been used. Early humans used sharp stones, bones, or wood pieces to cut and carve. The first effective knives were made out of flint. Even before that, knives were made out of a hard silicate form of the mineral quartz. They could be crudely formed into a palm-shape with a sharp edge which could be used for cutting, scraping, and other activities. These knives were shaped and sharpened against rocks.
With the invention of metal came great advancements in this early human tool. Humans learned the art of melting metals, which could then be molded into various shapes, including knives. As civilizations advanced, knives could be made out of newer and better materials. First came knives out of copper and bronze, and then iron.
These knives were often decorated with feathers; our ancestors took great pride in possessing a beautiful knife, as well as one that was relatively sharp compared to other knives of the period. Some knives were designed just for men, while others included designs specifically for women. These included fancy gold and silver designs for the upper classes. These jeweled knives were prized possessions, and were often carried in sheaths attached to a belt.
Once knives with metal alloys became possible, knives could be made out of many combinations of metals, first steel and then even harder materials. This paved the way for today's knives, made of stainless steel and similar alloys.
Since this early history, knives have been used for diverse activities including hunting, eating, tasks such as cutting wood or other materials, and as weapons. However, with the advent of guns and other forms of advanced warfare, the knife lost its place on the battlefield. Today, knives mainly serve domestic duties, or are used by hunters, campers, and other outdoorsmen.
Even though the materials and purposes of knives have changed greatly over the years, the shape of a knife has not changed much over time. The basic knife shape, with a handle and blade, was present even in the earliest knives. Although modern knives have more variations due to varying knife uses and more sophisticated technology for constructing knives, the basic concept remains unchanged.
Knife technology has come a long way over the past several thousand years. Today, rubberized handles, more advanced blade materials, and additional built in features make modern knives much more effective than their historic or even prehistoric counterparts. Modern knives may even utilize more complex materials such as titanium, ceramic, and carbon fiber, although steel is still widely used.
Today's knives also differ from historic knives mainly in how sharp they are able to become. Older technologies resulted in thicker and blunter knife blades. Today's knives can be much sharper, which results in easier to use knives. Older knife materials would have required much more pressure to be applied in order to cut the same materials, and they would not have been usable for precision cuts like the knives of today.

| Price : $65.99First introduced in 1990, the Spyderco Delica was one of the first lightweight, high-performance, one-hand-open pocketknives ever developed. A consistent best seller, it has evolved steadily over the years through Spyderco's CQI (Constant Quality Improvement) process. The Delica 4 features enhanced ergonomics, screw-together construction, and a four-position clip for versatile carry options. Its fiberglass reinforced nylon handles are molded with Bi-Directional Texturing for improved traction and control and are supported by dual skeletonized stainless steel liners. The liners increase structural strength without adding weight and provide a framework to anchor all external and internal components. Its VG-10 blade is flat saber-ground with a stronger tip and larger 13mm opening hole. This version is also black titanium carbonitride coated to reduce reflection and provide increased corrosion resistance. Phosphor bronze washers ensure a smooth action, and textured jimping on the spine guarantees positive control during use.
