Designed by Dmitry Sinkevich and based on his custom Headly, the Tumbler is a strikingly handsome EDC. The blade is high-performance D2 for a long-lasting edge and—with its high chromium content—improved corrosion resistance over other tool steels. The handle is G10 with a top layer of carbon fiber. The top layer isn't just glued on; it is an integrated part of the G10 material so it's incredibly durable. Kershaw machines the carbon fiber like the original Headly for amazing style. A custom pivot and backspacer complete the look of this must-have pocket knife.
Features
Flipper - May be used on either manual or assisted opening knives. The "flipper" is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle.
Manual - There is no mechanical assist, such as SpeedSafe, used to open the folding knife. It opens the classic, old-school way.
Sub-Frame Lock - One side of a lightweight handle, or frame, is fitted with a steel plate integral to the frame; it is the part of the frame that moves behind the blade to lock it into position during use. Sub-Frame Lock knives can be larger and lighter knife yet with an extremely secure lock.
Reversible - Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.

G10 Handles
Formed in a sheet under high pressure by combining fiberglass and an epoxy resin binder. These handles are lightweight and shaped to ensure a solid grip.
D2 Tool Steel
This semi-stainless tool steel offers great value, thanks to a high degree of edge retention that can often rival more expensive steels.
Frame Lock
Developed by Chris Reeve, it functions like a liner lock but the lock is comprised of one of the handle scales. It's an extremely strong and easy to manipulate lock.

Kershaw 4038 Dmitry Sinkevich Tumbler Flipper Knife 3.25" Stonewashed D2 Drop Point Blade, Black G10 Handles with Carbon Fiber Inlays
This is a small lightweight 3 inch D2 steel Kershaw pocket knife. A flipper with a linear block. Easy to open one hand, easy to close one hand. Came sharp out of the box. I carried this knifeeverywhere, it’s my go to knife. I’ve purchased three of these knives. The price is excellent. I highly recommend this knife if you want a small lightweight well-made pocket knife.
Kershaw 4038 Dmitry Sinkevich Tumbler Flipper Knife 3.25" Stonewashed D2 Drop Point Blade, Black G10 Handles with Carbon Fiber Inlays
This has been a great pocket knife. It is sharp out of the box, has a comfortable grip and has tight lockup. It looks great and is light as well.There are a couple of items to note if you are going to buy one. First, the textured CF inlays can make retrieving the knife from my pocket slower than some of my other knives. It's not hard to do, but there is just a little extra drag there. Second, the sub frame lock is just big enough that I needed to figure out where my fingers should sit when I try to flip it open. Neither of these things are a problem for me, but if I didn't catch this knife on sale and had paid list price, I would want to know about these issues.
