Estwing AUS-8 Folding Knife Review: A $13 Folder That Surprises

Introduction

Estwing has been around since the 1920s, built a reputation on forged-in-America striking tools, and only recently stepped into the folding knife space. The Estwing AUS-8 folding knife, picked up for about $13, is the result, and it raises an interesting question: can a tool company known for hammers and hatchets make a folder worth carrying?

To put the steel in context, we compared it against a Spyderco Endura, a well-regarded stainless steel lockback that sits at the other end of the price range. Interestingly, both knives use essentially the same class of stainless steel, which makes the comparison more about execution than metallurgy.

First Impressions

The knife leans heavily on classic Estwing styling: a bright yellow rubberized handle over hard plastic, with a shiny drop point blade. It measures about 8 inches overall with roughly a 3.25-inch blade. The highly polished finish is a departure from the satin finishes on most Estwing tools, though the branding and color language are instantly familiar if you grew up around their hatchets.

In the hand it fits well. The handle gives you three individual finger positions, with room for two fingers at the back, and a pair of thumb studs up front. There is no jimping, which matters later. For a knife at this price, the fit and finish of the handle over-mold is genuinely pleasant.

The Lockback Mechanism

This model uses a lockback mechanism, clearly reminiscent of the Spyderco Endura’s design. Under pressure testing the lock holds, and the release requires a good amount of bite before the blade frees up. That is reassuring from a safety standpoint.

The odd part is the closing action. There is uneven resistance along the closing arc: the spine of the blade seems to have some unevenness in the machining, so the blade moves smoothly, then hits a patch of resistance, then falls free. It behaves like a heavy restaurant door: smooth, then sudden resistance, then everything slams shut. That kind of snap is an old-school lockback trait and it is a real cut risk, since a thumb that has slipped off the stud can land on the serrations. It is easy to fix with better machining, and Estwing should clean it up.

Fit, Finish and Build Quality

There are a few quality-control tells here. The Torx pivot screws look rough, with visible gapping you would never see on a custom knife, and the spacing between parts is not perfectly lined up, with small air gaps visible from the side. None of this is surprising at this price, but it is worth setting expectations.

The stainless steel liners are fully lined rather than skeletonized, with the composite rubber over-mold on the plastic handle. A stainless steel pocket clip is included and works fine. If you want a smoother lock action, Estwing also sells a liner lock version for a little over $20 that includes a flipper, which may be the better and simpler system.

Sharpness and Cutting Performance

Out of the box, this knife is sharp. With AUS-8, that should not be elusive: it is a common, not spectacular, but definitely good knife steel, and how it performs depends heavily on heat treatment. Estwing clearly knows how to heat treat tools, so the hope is that quality control carries over to their overseas production.

The blade combines a main edge with a small serration section on one side, which is handy for cutting wet materials like rope and wet cloth. The drop point profile has a touch of swedging and the tip is finished quite nicely, which is often where budget knives get dinged. One drawback: the spine is completely smooth, so it will not throw sparks from a fire steel the way a sharp 90-degree spine on a bushcraft knife will.

How It Compares to the Spyderco Endura

Put side by side, the Spyderco Endura and the Estwing technically share the same class of stainless steel. The difference is everything around the steel. The Endura’s lockback closes with a consistent, controlled motion, while the Estwing has that resistance-then-snap behavior. The Endura’s fit and finish is tighter throughout.

That said, the Endura costs significantly more, and the Estwing is not pretending to be its equal. At $13, some gapping and a quirky closing action are acceptable trade-offs for a knife with good steel, a nice tip, and a comfortable handle.

Buying Advice

This is a great gift knife and a sensible first folder for someone starting out, or a beater you will not worry about. The bright color makes it easy to find, the steel takes a good edge, and the price removes all hesitation.

If you can spend a little more, the liner lock version at around $20 looks like the more refined option and is worth trying. If you want a genuinely smooth lock action and tighter tolerances, the Spyderco Endura remains the benchmark for a stainless lockback.

Conclusion

Estwing’s first folding knife surprised in the best way. It is not flawless, and the uneven closing resistance is the main thing to know before buying, but for $13 you get classic styling, a comfortable rubberized handle, sharp AUS-8 steel, and a lock that holds. As a gift knife, starter folder, or knockabout companion, it is an easy recommendation.
