Petrified Fish Buun 868 評測：一款只要 35 美元卻很稱職的折疊刀

Introduction

有些刀靠著頂級鋼材與高昂價格贏得追隨者。Petrified Fish Buun 868 走的是完全相反的路線。它是一款小巧的折疊刀，售價約 35 美元，卻配備 D2 工具鋼刀刃、不鏽鋼內襯，而且做工與完成度經得起數個月使用，而非只有幾天。

Petrified Fish 是一家總部位於中國大陸的公司，約在 2020 年成立，以採用優質零件、功能豐富的平價刀具建立起口碑。Buun 正是這個公式的明顯例子。

經過幾個月的每日攜帶後，這把刀處理過繩索、紙箱、膠帶與包裝材料，還應付了幾次臨時維修工作。它保持鋒利、開啟順暢，樞軸處也沒有晃動。在這個價位，這樣的組合很難挑剔。

Who This Knife Is For

這是一把折疊的日常攜帶刀，而非專門的野外求生工具。它適合想單手快速展開刀刃、且整天放在口袋也很舒適的人。

The design leans on a flipper tab, so the blade snaps out with a short push of the index finger. A thumb stud and a thumb hole offer two more opening options, which means the knife works across different hand sizes and different habits. The company also produces a range of other folding models, with one fixed blade in the lineup.

It is a good match for day-to-day chores, general safety tasks, outdoor trips, and light duty work around a vehicle, a campsite, or a workshop. Anyone looking for a heavy chopping tool should look elsewhere, because this is not that knife.

Main Strengths: Blade and Edge Performance

The blade measures 3.3 inches and is 3.6 mm thick at its thickest point, which gives it a substantial feel without making it clumsy. The steel is D2 tool steel, a material known for holding an edge well.

The grind is a full flat grind across most of the blade, and the profile is a modified drop point that reads as a hybrid between a drop point and a spear point. The shape puts a useful belly behind the edge, which is why it slices through rope, cardboard, and plastic cleanly.

Out of the box the edge was razor sharp, and it has stayed that way through repeated use. D2 in this knife strikes a practical balance: it keeps a working edge for a reasonable stretch of time, and it can still be sharpened without a struggle. That matters more than raw edge retention for most owners, since a blade that is easy to bring back is a blade that gets used. Corrosion resistance is mild rather than excellent, so a little routine care goes a long way.

Main Strengths: Handle, Lock, and Carry

The handle is 4.5 inches long, and the total length of the knife opened is 7.9 inches. Handle scales are available in G10 or Micarta, and the G10 version comes in black, gray, and green. Stainless steel liners sit underneath, paired with a stainless steel liner lock.

In the hand, the scales feel smooth without being slick, and the light texture helps the knife stay put during a cut. Jimping near the blade gives the thumb a place to press down when more force is needed, whether that means shaping a feather stick or cutting through stubborn material.

The lockup has been solid throughout use, with no movement and no sign of the lock releasing under load. Deployment is fast and clean, partly because the blade carries enough momentum to swing out with a flick. The deep carry pocket clip is set into the handle rather than sitting on top of it, and on the G10 version it can be moved to either side. There is also a lanyard hole at the rear for anyone who wants a tether.

Build Quality and Real-World Value

For $35, the build quality is the headline. The knife arrived free of scratches and imperfections, the scales line up precisely with the liners, and the blade sits tight in the frame with no play in any direction.

That quality showed up in use rather than only in inspection. The knife has cut through cordage, tape, boxes, and packaging, and it has also handled less ordinary jobs, including trimming bent plastic so a damaged bumper could be tied back into place and cutting through a broken tent pole so a repair could be made on the trail. The belly and the sharp edge made short work of both.

Value is the other strong point. Finding a knife this sharp, with these materials, this feature set, and this level of finish at this price is a difficult assignment. The Buun makes a convincing case that a budget knife does not have to feel like a compromise.

Things to Consider Before Buying

Weight is the first consideration. At 5.1 ounces, the Buun has real heft. Some of that weight is what makes the flipper action so satisfying, since the blade carries itself out of the handle, but anyone who prefers the lightest possible carry has lighter options available.

The pocket clip deserves a note as well. Because the clip is integrated into the scales, moving it to the opposite side means removing the scales first. That is not difficult, but it is worth knowing in advance. The knife ships set up for right side carry, and while the G10 version allows the clip to be swapped, there have been reports that the clip on some Micarta versions is not ambidextrous.

Finally, keep expectations aligned with the design. This is an everyday carry folder, not a bushcraft knife, and D2 here offers mild corrosion resistance rather than the highest available. Neither point is a flaw, but both shape how the knife should be used and maintained.

Buying Advice

At around $35, the Buun 868 is priced in budget territory while carrying features and materials that are usually associated with more expensive knives. Buyers who value a fast, satisfying flipper, a D2 blade that is easy to maintain, and a solid liner lock will get a lot for the money.

Choosing between handle options comes down to preference. G10 is the version that clearly supports moving the pocket clip to either side, while Micarta offers a different look and feel. Colors across the G10 line include black, gray, and green. Anyone who dislikes a heavier carry should weigh the 5.1 ounce figure honestly before deciding, and anyone who wants a folding blade for light maintenance work, general chores, and outdoor trips will find the size and shape well judged.

Conclusion

The Petrified Fish Buun 868 is a no-nonsense budget knife that delivers on the basics. It arrives razor sharp, the edge is straightforward to maintain, the build quality is excellent, the deployment is smooth, and it holds up as a daily carry blade. It may not be the lightest or the most stylish option on a shelf, but at this price it looks good, comes in several finishes, and has proven itself reliable and capable. For anyone shopping in the budget range, it is worth a serious look.
