			Spyderco featured Bob Terzuola in their [http://www.spyderco.com/byte/2014_02_february/index.html February 2014 issue of Byte], with the following article:

			''Widely recognized as the father of handmade tactical folding knives, Bob Terzuola, or “Bob T” as he is affectionately known, is one of the most influential figures in custom knifemaking. He also has the distinction of being the first custom knifemaker to collaborate with a major knife company to offer the advantages of his custom designs in a production knife. With his help, Spyderco pioneered the concept of custom knifemaker collaboration and literally changed the face of modern knife manufacturing.''

			''Terzuola was born in Brooklyn, New York is a graduate of New York University. In 1967, he moved to Panama to work as a Peace Corps trainer and ultimately studied jade carving and gemology in Guatemala. While living in Guatemala, he also developed an interest in knifemaking and by 1979 was making handmade knives for soldiers there. In 1981, he returned to the U.S., settling in Santa Fe, New Mexico, joining the Knifemakers Guild, and focusing on crafting exceptionally refined fixed-blade and folding knives. His exceptional understanding of tactical knife design made his knives the tools of choice of many savvy military and special operations personnel worldwide. A gifted teacher and mentor, he is also the author of The Tactical Folding Knife, a definitive work on his meticulous method of custom knifemaking.''

			''Terzuola’s first Spyderco design, the C15 Terzuola, was introduced in 1990. It was not only the first Spyderco LinerLock®, it was also the first US-made Spyderco knife and the first to feature a two-position clip. This popular design later inspired a smaller version called the C19 Terzuola Jr., which was introduced in 1994. These designs and Terzuola’s strong desire to have them made in the U.S. were instrumental in the establishment of Spyderco’s Golden, Colorado factory.''

			''In 1999, Spyderco released the C55 Starmate. Based on Terzuola’s most popular custom designs, the Century Starfighter and the ATCF, the Starmate was one of the first production knives to be modeled directly on a signature custom design. It became an instant classic and set a precedent for the many custom collaborations now common in the knife industry. The Starmate remained in the Spyderco line for several years before being discontinued. Its popularity with dedicated end users and collectors never waned, however, and prompted the introduction of a revised version in 2012.''

			''One of Terzuola’s lesser-known Spyderco designs was the C131 Ball Joint SLIPIT™. Externally, this unique knife displayed the classic lines and styling of a Bob T design. Internally, however, it featured a unique “Ball Joint” non-locking mechanism that used ball bearings inset into integral springs cut from the handle liners to help keep the blade open during use. One of the most interesting variations of Spyderco’s one-hand-opening, non-locking, clip-carry SLIPIT line of knives, it is now a prized collector’s item.''

			''The latest addition to the family of Spyderco/Terzuola collaborations is the Double Bevel. Named for its most distinguishing characteristic, this compact LinerLock folder features a unique double-ground blade. Near the heel of the blade (closest to the handle), it is hollow ground and has a full thickness spine for strength. Near the tip, the blade is full-flat ground with a gradual distal taper and a swedge. The point is a Bob Lum-inspired Americanized tanto that, unlike the conventional faceted tip, flows gracefully into the bevels of the flat grind. Offering the best of both worlds—strength and low-friction slicing performance—this unusual grind makes the Double Bevel an amazingly capable pocket-sized cutting tool.''

			''Spyderco is incredibly proud of its association with Bob Terzuola and our ability to share his distinctive style and design genius throughout our history.''

			''Michael Walker’s LinerLock® mechanism revolutionized modern folding knives and was quickly adopted by many savvy custom knifemakers. None, however, have contributed more to the continued evolution of that lock mechanism than Bob Terzuola.''

			''A properly made LinerLock must take into consideration a number of critical factors to function reliably. The angle of the tang ramp, the length, thickness, and spring tension of the lock bar, and the angle of the lock bar face must all work in concert to ensure the blade locks securely, while still allowing it to be easily released to close the knife. While most traditional LinerLocks use a flat tang ramp, Terzuola took a different approach.''

			''Terzuola took a hard look at the motion of the lock bar and realized that the contact surface at the end of that bar (the lock face) traveled at the end of a radius. Rather than contacting a flat ramp, he believed the lock would work better if the tang ramp was also cut as a radius. Through extensive experimentation and testing, he perfected a method of grinding a concave ramp on the tang of the blade that maximized the galling (the tendency of two contacting metals to “stick” to each other under friction) pressure of the lock bar’s face and the tang ramp. The geometry of Terzuola’s concave ramp also included a small “lip” at the outer edge of the ramp that helps prevent the lock bar from sliding off the ramp under pressure. This is the most common form of lock failure with traditional flat tang ramps. Terzuola’s improved geometry causes the lock bar to snag on the lip, significantly increasing the lock’s strength and dramatically reducing the chances of lock failure.''

			''Although this method of LinerLock construction is more costly and time consuming than conventional methods, Spyderco proudly features it on all our Terzuola-designed LinerLock knives.''

			''If you’d like to learn more about the details of Bob Terzuola’s approach to LinerLock geometry, as well as his other unique knifemaking methods, he literally “wrote the book” on the topic. That book is his best-selling work The Tactical Folding Knife, which belongs on the shelf of every serious knife enthusiast.''
