C183 Burch Chubby:

"Michael Burch is a custom knifemaker who specializes in high-performance folders painstakingly crafted one at a time. Based on one of his most popular models, Spyderco’s Burch Chubby is a stout, highly functional folding knife that packs an impressive amount of cutting edge into a very compact package.

Aptly named, the Burch Chubby is wide and thick in comparison to its length and provides a satisfying hand-filling heft. Its broad blade is precision machined from 0.175-inch (4.5mm) CPM S30V stainless steel stock for extreme strength and durability. This thickness is offset by the blade’s wide profile, a deep hollow grind, and a pronounced swedge (unsharpened bevel) on the back. Collectively, these features complement the blade’s long, sweeping cutting edge to provide exceptional edge geometry and cutting performance that far exceeds its compact size. Spyderco’s Trademark Round Hole™ completes the package and ensures swift access to the blade with either hand.

The handle of the Burch Chubby is constructed of two solid titanium scales joined at the butt end by a G-10 back spacer. In classic Burch style, the obverse scale features three precisely fitted round carbon fiber inlays that contrast beautifully with the matte gray of the bead-blasted titanium. The other scale is home to the knife’s sturdy Reeve Integral Lock (R.I.L.) mechanism, which locks the blade securely into place when opened. To support convenient carry and keep the Burch Chubby instantly accessible, it features a custom-designed pocket clip configured for right-side, tip-up carry. The broad profile of the clip enables it to hold the knife securely to the pocket, yet ensures a smooth, snag-free draw. It also provides an excellent purchase for your fingers when opening the knife one handed."
