Information from the Spyderco catalog on the web

"Non-locking folding knives aren’t a new concept. They’ve been around for centuries without much change but continue selling among a sea of modern locking knives. The reason? While many knife buyers appreciate the traditional aspects of a non-locker, more want this type of knife because they live or work where laws prohibit carrying and using a locking pocketknife.

Spyderco perceived a gap between traditional slipjoints and modern locking folders and created a product line called SLIPITS. SLIPITS offer reliable and sophisticated non-locking folders that open with one hand, have a finger choil for comfort and safety and are conveniently accessible.

As the overall SLIPIT line expands, a subcategory of micro-sized SLIPITS with stainless steel handles is populating within and Spyderco calls them Bugs. The first Bug was matter-of-factly named, The Bug. Its non-locking blade is just barely over an inch long. Next up, a two-inch blade called the HoneyBee followed by the release of a larger one yet, The GrassHopper. Affable Bugs draw comments like “how cute” - a beneficial perception in a knife-cautious world but their size trumps the reality that they’re serious business when it comes to cutting.

The GrassHopper’s size is closest to that of a true penknife with its blade over two-inches. Its PlainEdge Cr13 stainless steel blade stays open when you’re cutting, held by resistant pressure at the knife’s pivot area. GrassHopper handles are chamfered with no squared-off edges to dig or bite into a gripping hand. The handle is also stainless steel with a laser engraved Spyderco bug and enough blank area for a small amount of engraving or customization as jewelry or a gift item. Handle lanyard-hole welcomes a chain for wear around a neck or a keychain." The C138 GrassHopper in Spyderco's online catalog
