       n 1990 Spyderco shook things up by introducing 
		two knives, the Delica and Endura. First of their kind on the market, 
		both folders opened up the knife market to lightweight performance, 
		one-hand open pocketknives that just about everyone could afford. They 
		settled as Spyderco’s top two bestsellers and their improvement hasn’t 
		slowed since. Refinement has been so ongoing and continual Spyderco 
		tagged the updating/upgrading process with the term CQI- Constant 
		Quality Improvement. During the Endura and Delica’s CQI journey Spyderco 
		tweaked ergonomics, refined blade steels and fine-tuned their 
		performance countless times. They are an evolutionary work in progress 
		and the next level is here with the new Endura4 and Delica4. Both models 
		now have screw construction making cleaning and adjusting easier. The 
		fiberglass reinforced nylon handles come molded with Bi-Directional 
		Texturing® for preferred traction and improved ergonomics. Inside the 
		handle dual skeletonized stainless steel liners make the knife stronger 
		without adding weight and make an anchor for all external and internal 
		components to attach through adding sturdiness and rigidity. Their VG-10 
		blades are flat saber-ground with a stronger tip and larger 13mm opening 
		hole. Added to the blade’s spine is slip resistant jimping. Phosphor 
		bronze washers smooth out the open/close action and the clip is upgraded 
		to a four-way tip-up, tip-down, left- or right-handed clip..  |
