This is a very hefty, well designed folding knife. The liners are thick
on both sides of the handle. The blade material is top notch CPM-M4
carbon steel - not stainless. This is a tool steel that has over 6 times
the wear resistance of D-2 steel at the same hardness.
Here is Spyderco's information:
For those not familiar with Gayle Bradley, he produces handmade folders
and fixed-blades. He’s a Texan who started making custom knives in 1988
and when customers discovered his handmades, his reputation mushroomed,
tagging him as a knifemaker who focused on building exceptional knives
for hard-use. We believe you will find our Spyderco collaboration
impressive not only in its performance abilities but in it’s fine
appearance as well.
Several years ago Gayle won a BladeSports World Cutting Competition
further expanding his reputation by claiming his title with a
fixed-blade that plowed through everything including eleven-inches of
hanging rope. Bradley knives aren’t for fingernail cleaners or showmen
but for use down on the ground – getting gritty and dirty. His first
collaboration with a production company we’re glad to say is with
Spyderco. The C134 Gayle Bradley Folder pulls together his reputational
forte; anteing up a hard-use folder design to which Spyderco added an
exotic and premium blade steel and an unexpected touch of
The blade is hollow-ground satin finished Crucible Steel CPM-M4.
Original M4 made its good name as a tool steel with high resistance to
impact. Crucible’s version incorporates their CPM-powdered metal
manufacturing process with M4 creating a superfine, consistent
steel-grain structure heightening its’ already impressive impact
resistance even more. Its modified drop-point blade also has a
weight-reducing swedge located at the spine.
The handle is twill carbon fiber with a Michael Walker LinerLock® for
safe, secure lock up while adding a refined, gentlemanly appearance.
Inside are two full-length internal liners adding rigidity to the handle
that has screw- together construction for adjustments or cleaning. A
four-way hourglass clip lets you choose to carry the folder;
tip-up/tip-down, left/right handed..
