The Manix model started as a dedicated hard-use design from the mind of Eric Glesser, son of Spyderco founder Sal Glesser. Eric designed the original Manix to be a large, ergonomic, tough, workhorse of a knife. And it was. The original Manix was approximately the size of the current Manix XL (almost 9" overall) and utilized a sturdy back lock mechanism. To make the folder more carry able and user friendly, later versions reduced the size and eventually switched over to Spyderco's patented Ball Bearing lock. Another accolade of this enuring design is the Lightweight version of the Manix winning Blade Show's "Most Innovative American Design" award in 2010.
The Ball Bearing lock is a unique, self adjusting lock that is incredibly strong and user friendly. It uses a large steel ball bearing (hence the name) that wedges between the tang of the blade and the steel housing that holds the locking mechanism. Because the bearing is circular, it can adjust and seat itself deeper onto the tang of the blade over the knife's life, ensuring consistent, strong lockup. Users actuate the lock by pulling down on each side of the textured plastic cage that surrounds the ball bearing, making is easy to use for most hand sizes and while wearing gloves.
