A glass breaker can be useful on an EDC knife, but it also means carrying a pointed piece of hardware in your pocket every day. Emergency features may make a knife more versatile, yet they can add bulk or snag-prone protrusions to a tool that will spend most of its life opening packages and handling ordinary cutting jobs.

The Petrified Fish PFE20 Bat takes a different approach. It combines a 3.27-inch N690 stainless steel blade and G10 scales with what the company calls a Modular Tail System, which lets owners change the attachment at the end of the handle rather than permanently committing to a single emergency-focused feature.
For anyone who wants an EDC folder with a little more flexibility than the standard blade-and-handle formula, that may be the Bat’s strongest argument.
A 3.27-inch blade for EDC
The PFE20 Bat uses a 3.27-inch N690 blade, putting it in a useful size range for the ordinary jobs that justify carrying a pocket knife.
Think packages, cord, tape, cardboard, and the countless other small cutting tasks that appear during the day. A blade around this size provides substantially more working edge than a tiny keychain knife without moving into oversized-folder territory.
Petrified Fish uses N690 stainless steel for the blade. It is an established knife steel, but that specification alone does not tell us exactly how long this particular blade will hold an edge or how it will compare with another manufacturer’s knife. Blade geometry, heat treatment, sharpening, and the materials being cut all affect real-world performance.
The more useful takeaway is that the Bat pairs its unusual modular feature with a recognizable stainless blade steel rather than making the tail system the knife’s only point of interest.
The key feature is at the tail
Most folding knives offer little reason to focus on anything beyond the blade, handle, pocket clip, and locking mechanism. The Bat’s Modular Tail System is the exception.
One early owner reported receiving a removable glass breaker and a small pin spanner for fitting it. If that configuration is included with retail versions, it would let owners fit the emergency tool when it makes sense instead of carrying a pointed breaker permanently attached to the knife.
The appeal is simple: drivers or preparedness-minded users may value the glass breaker, while someone who wants a straightforward daily cutting tool may prefer the cleaner profile without it.
That is more useful than simply adding another feature to a specification list. Plenty of EDC products include tools that sound reassuring but rarely get used. Making one of those features removable acknowledges that different owners have different priorities.
There is an important limit, though. The modular interface may suggest other possible attachments, but buyers should not assume a broader ecosystem exists unless Petrified Fish announces one. For now, the documented accessory is the removable glass breaker reported by an owner.
Early feedback is limited
Because the PFE20 Bat is new, there is not enough independent testing to make confident claims about long-term durability or performance. One early owner reported that the blade arrived centered and sharp and described the fit and finish positively. The same owner said deployment initially felt somewhat stiff but was improving with use.
Those observations are useful, but they come from only a few days of ownership. One well-centered example does not establish manufacturing consistency across every Bat, and short-term use cannot tell us how the pivot, scales, blade, or modular tail will behave after months of regular carry.
For now, the evidence gives us a positive first impression rather than a long-term verdict. Specifications tell us what the product is supposed to offer, while early owner reports can show whether an individual example delivers on some of those basics. Neither substitutes for extended testing.
A small, useful change
The Bat is still fundamentally a folding pocket knife, and that is probably the best way to judge it. Its G10 scales and 3.27-inch N690 blade are the parts that matter during normal cutting tasks. The Modular Tail System does not turn the Bat into a multitool, and attaching the glass breaker does not suddenly make it a complete emergency kit.
Instead, the system solves a smaller but believable problem: not everyone wants the same hardware permanently attached to their knife.
That makes the concept more interesting than simply adding another tool. You can configure the knife around how you actually intend to carry it rather than accepting an emergency feature whether you need it or not.
Who should buy it?
The PFE20 Bat makes the most sense for someone who wants a medium-sized folding knife but also appreciates EDC designs that experiment with something beyond another blade shape or handle color.
The 3.27-inch N690 blade provides the conventional foundation, while the G10 scales keep the construction familiar. The Modular Tail System gives the Bat its identity, particularly for anyone who likes having a glass breaker available but does not necessarily want one permanently protruding from a pocket knife.
Buyers who prioritize a proven design with years of reviews and long-term testing may want to wait. The Bat is new, and evidence about durability remains limited.

But if you are comfortable buying a newer design, the Bat offers a genuinely interesting twist on the familiar EDC folder. Its cleverest feature is not another tool you are forced to carry. It is giving you the choice of whether that tool belongs on your knife at all.
