happy to, chief!
Robert (Bob) Terzuola is a custom maker, still very much producing custom knives. he is often referred to as the father of the modern tactical folder.
he wrote the book on it, literally:
http://www.amazon.com/Tactical-Folding-Knife-Construction-Liner-Locked/dp/0873418581it has become become such a classic that even used copies bring $200, as this amazon web page shows.
he has a huge following and his own forum over at Usual Suspect Network (but you need to be a member to view it i believe)
http://usualsuspect.net/forums/forumdisplay.php?f=311.
he also designs many knives for major production manufacturers like Benchmade and Sypderco.
i've owned a number of his knives over the last 20 years and this one is my very favorite. some of his folders sell for many times more than this one, when he uses rare materials or they're engraved. he doesn't have a website (he says he doesn't need more publicity because he has enough work already), but a google search of his name will pull up lots of examples of his work.
Bob listed the size as 9" open, 5" closed and having a 4" blade. blade thickness is 5/32"
(my rough measurements show 8.75" open, 4.75" closed and just under 4" blade, with a total grip thickness of 5/8")
fyi - top-edge is not sharpened.
blade steel is CPM154 (which is visibly etched on the blade) which many consider the finest knife steel ever. it is a higher grade version of standard 154-CM, which itself is still the industry standard for quality knives:
CPM154CM is similar in composition to 154CM (and similar in composition to ATS34), but is a crucible particle metallurgy tool steel, made of sintered alloys formed together. This is Crucible Steel's version of the 154CM, made to better tolerances and, with the crucible particle manufacturing process, an even distribution of alloying elements. It is much like ATS-34 in that it is a high molybdenum stainless tool steel, and very tough (resistant to breakage). One might ask why even use ATS-34, since the two are so similar in composition. The CPM154CM steel is expensive. Very. And sizes are limited. The cost of making a knife in this material and finishing it are more expensive, so one must question why they might need it. CPM154CM does excel in one area, and that is finish. This steel finishes absolutely beautifully. The mirror finish is even, smooth, and uniform with no crystalline pattern that can be seen with the naked eye. My recommendation for using this steel is on a high art or investment grade knife of fairly standard sizing, where a supreme finish and high toughness are needed.
