The Custom EXK Plus is a robust custom creation from knife maker Trevor Burger. This lightweight Gentleman's folder is perfect for everyday carry with a slim profile, clean lines and high performance materials. Excellent fit and finish paired with a well-thought-out design make this a dream to carry and use. This version comes with an Acid Washed M390 modified Sheepsfoot, carbon fiber bolsters and natural Micarta scales.

Brand new, direct from Burger Custom Knives, ZA.

Blade: The tumbled, acid washed M390 blade is a modified Sheepsfoot with plenty of belly and a reverse Tanto point. Shallow hollow ground, the blade is excellent for slicing and piercing with a top swedge for added style. Bohler's M390 provides top of the line performance with minimal maintenance. Riding on a ceramic ball bearing pivot the blade deploys fast and smooth via a front flipper tab. Jimping allows for a slow, "manual" rotation deployment or a faster "flipper" operation.

Handle: Blue anodized, dual titanium liner construction supports the Micarta scales that are flush fit with carbon fiber bolsters. Smooth, natural Micarta offers traction without being aggressive while blue anodized collars set off the custom pivot hardware. One liner forms the simple, robust liner lock mechanism delivering secure use and ease of operation.

Carries via a blue anodized, right hand, tip-up, 3D machined titanium pocket clip.

This custom ships in a zippered nylon pouch with Certificate of Origin. 

Bohler M390: Bohler M390 has become an extremely popular choice for high-end user grade knives thanks to its exceptional edge retention. M390 also has a good corrosion resistance, meaning most users can avoid problems by simply wiping off their blade after each use. Another great feature of this steel is the ability to resist burr formation during sharpening. Comparable steels are CTS-204P and Duratech 20CV.
