Significant Inventions/developments
One Piece concept – The concept of a fixed blade, hollow handled knife, with both the handle and blade milled from a single billet of steel.
Lock 45 – A folding knife lock, formed by a lock bar with recesses containing 45 degree angles mating with the rear of the blade. The lock bar / blade interface serves as both the blade stop and the lock mechanism.
Helix Lock – A modification of the Opinel folding knife ferrel lock, which enables one-handed opening and closing.
Integral Lock© – A folding knife lock, introduced with and popularized by the Sebenza folding knife, where one of the handle slabs is slotted to form a lock bar, which falls into place behind the blade to stop the blade from closing.
CPM S30V – A stainless steel using the powder metallurgy process. Reeve worked with the Crucible Steel Company to develop this steel specifically for the cutlery industry.
Kubuli serrations – Serrations placed in a knife blade, alternating from both left and right sides of the blade, forming two rows of serrations that are not collinear. As a result, Kubuli serrations move the material to be cut from side to side as the cut is being made.
Perforated thrust washers – Initially brought to market by the Umnumzaan folding knife in 2008, Reeve's design of perforated washers reduce pivot friction, and serve to retain lubricant. After their successful employment in the Umnumzaan, perforated thrust washers were incorporated into the design of the Sebenza.
Ceramic ball integrated into integral lock bar – Also introduced as a feature in the Umnumzaan, the ceramic ball embedded into the end of the lock bar, creating the interface between the blade locking surface and the integral locking arm surface. The ball doubles to drop into a mating detent on the blade to ensure that the blade does not open accidentally.

Famous quotes containing the words significant, inventions and/or developments:
“As between these two, the need that in its haste to be abolished cannot pause to be stated and the need that is the absolute predicament of particular human identity, one does not presume to suggest a relation of worth. Yet the distinction is perhaps not idle, for it is from the failure to make it that proceeds the common rejection as “obscure” of most that is significant in modern music, painting and literature.”
—Samuel Beckett (1906–1989)
“The treasury of America lies in those ambitions and those energies that cannot be restricted to a special, favored class. It depends upon the inventions of unknown men; upon the originations of unknown men, upon the ambitions of unknown men. Every country is renewed out of the ranks of the unknown, not out of the ranks of those already famous and powerful and in control.”
—Woodrow Wilson (1856–1924)
“I don’t wanna live in a city where the only cultural advantage is that you can make a right turn on a red light.
Freedom from labor itself is not new; it once belonged among the most firmly established privileges of the few. In this instance, it seems as though scientific progress and technical developments had been only taken advantage of to achieve something about which all former ages dreamed but which none had been able to realize.”
—Hannah Arendt (1906–1975)
