One of my pet peeves about knives, which will either lead me into a steady diet of yoga and meditation, or finding a really understanding therapist, is blade steel.
Just because a new steel hits the scene, doesnβt necessarily mean itβs better than the steel itβs poised to replace. In fact, that new steel might not even replace an older steel, it just ends up compared to a handful of existing steels weβve come to know and love. In doing that, some excellent steels may be forced out of the limelight.
Iβm here now to celebrate one such steel: Elmax, a powdered stainless steel lauded for its high levels of wear resistance, compressive strength, dimensional stability, and resistance to corrosion. In fact, I see it as a steroid steel that excels in every aspect β akin to M390, 20CV, and XTS-HTP. All of those fell out of favor because they were so damn expensive.
But I suspect Elmax has come back around, with MagnaCut being all the rage right now. After all, Elmax and MangaCut go toe-to-toe in terms of desirable EDC knife steel characteristics. Both are considered super steels and βall-around goodβ EDC knife steels.
And the knife that brought Elmax back to my attention? The Biblio XL, a flipper-style, creatine-packed big brother of the original Biblio folder made by GiantMouse. The brainchild of Danish knifemakers Jens AnsΓΈ and Jesper Voxnaes, and American entrepreneur Jim Wirth, GiantMouse targets βamazing knife designs, with the highest possible production quality, at a fair price.β
After a few weeks of carrying the Elmax variant of Biblio XL around and subjecting it to the abuse it deserved, I can attest that it ticks every box.
In short: GiantMouseβs Biblio XL is a full-size, premium EDC knife made from proven materials β at a price that is fair for what you get.

GiantMouse Biblio XL Knife Review
Design & Features

For a knife that GiantMouse markets as βformidableβ and βa powerhouse,β I find the Biblio XL is really the ideal size for my kind of everyday carry. At 7.56 inches, and with a 3.2-inch blade, itβs about as balanced as you want a pocket knife to be.
Its double-choil design and curving spine make for a great natural feel in your hand and offer a variety of hand holds.
The Elmax steel blade on the GiantMouse Biblio XL is a fat, curvy drop point. This blade shape is great for a variety of tasks, from slicing up fruit and meat, to prepping kindling (and anything else in between).
All of this allows the Elmaxβs impressive corrosion and abrasion resistance to shine. Out of the box, the blade edge is sharp enough to shave the skin off of a tomato. Thatβll hang around for a while and shouldnβt be too much of a challenge to restore β with the right sharpening tools.

Being that the Biblio XL is a ball-bearing-driven, flipper-style knife, I would have eliminated the oversized thumbhole in the blade. But being that all of the flat edges of the blade have been rounded, it serves as the one place you can run a ferro rod through to get a fire going. So, Iβm happy itβs here.
Additionally, the thumbhole offers a secondary option for opening, which this knife does very well. Its liner lock also does a stellar job of keeping the blade in place until youβre ready to put it back in your pocket.
Both the canvas Micarta handle scales and the brass backspacer provide a classic look when juxtaposed against the stonewashed blade and hardware. Theyβll patina nicely over time.
Do yourself a solid and throw a nice lanyard and bead on this knife. I chose some navy 550 Paracord and a PDW Memento Mori GID Bead. Sometimes itβs the little details that drive you crazy but make the knife your own.

Rounding out the features of the Biblio XL is an ambidextrous, deep carry, wire pocket clip. For years, I complained about this style of pocket clip. However, given that I jacked up a standard steel pocket clip on a different knife recently, I realize Iβm a little hard on the knives I use.
This pocket clip has some side-to-side flex to it, but it slides in and out of my pocket without leaving much of a mark, so I am happy to give it a shot.
First Impressions
If materials are what draw you to a good knife, then the way it fits in your hand is what will keep you using it. Over time, you figure out what blade steel you like. And you discover what handle scales are the best for your day-to-day life. And, eventually, you learn whatβs going to feel best in your hand.

When I saw the first image of the Biblio XL opened up and laid out across a satchel with a compass and some spent rounds, I could see it was going to fit my hand fantastically. The way the handle was shaped, and how the spine of the blade arced and flowed, promised that everything would line up just about perfect.
And I was right. The knife sits in my paw right where I want a knife that I plan on using and abusing. Itβs so on the money, in fact, that my thumb lands right in the middle of the specifically placed spine jimping.
GiantMouse chose to keep the size of the flipper tab on the Biblio XL minimal, and I really appreciate that. Itβs big enough to deploy the blade with ease, but not so big that it becomes an obstacle when the knife is open. And the deployment is butter-soft. It requires very little effort to lock the blade up.
Iβve already professed my admiration for Elmax steel, but it really plays well in this stocky, stonewashed drop-point form, as do the green canvas Micarta handle scales. I look forward to them taking on a tarnish, along with the brass backspacer. The Biblio XL is the kind of knife that looks great out of the box but starts to look even better when broken in.
Elmax vs. MagnaCut

I spent most of 2023 testing knives with MagnaCut blade steel. MagnaCut was last yearβs βitβ steel and for good reason: Itβs universally good if not great.
So that said, I have a heightened awareness of how MagnaCut will perform and I canβt find any distinguishable characteristics scenarios where it outperforms Elmax. And thatβs not just me; from everything Iβve read, itβs the general consensus β with the one caveat being that MagnaCut will be easier to sharpen when the time comes.
The other differentiator is that MangaCut is more affordable. This was most definitely aided by the fact that every well-known knife manufacturer on the planet released a MagnaCut knife last year, and is still doing so this year.
So, just like it was in 2009 when it first hit the market, the one thing people pooh-pooh about Elmax is its price. But at $225, I find the Biblio XL sits on the lower end of the price spectrum for knives of this caliber and construction.
Maybe Elmax has finally come down in price? Maybe itβs not a big deal? Either way, youβre getting a lot of knife here for a nice price.

Biblio XL in the Field
So, what did I do with the GiantMouse Biblio XL? Well, I lived with it. Not only was it my EDC for a few weeks, but I also took it hiking, and we went camping.
I spent nights by the fire with the Biblio XL and afforded it plenty of opportunities to play in the snow, stab into driftwood, or just get wet and gritty. I even showed my kids how easy it was to shave the hair off your arm with it.
I also spent nights starting fires with the Biblio XL. With all of its rounded edges, that wasnβt easy. But I stuck with it, and the Biblio managed to fulfill the task.

Like a lot of the folding knives I review, the Biblio XL checks off a lot of EDC requirement boxes. It looks the part, feels the part, and acts the part of a knife that you throw in your pocket for prolonged periods. Itβs the kind of knife you can abuse with just a quick wipe-down before the next round.
Iβve really enjoyed my time with it and look forward to using it again and again.
GiantMouse Biblio XL Knife: In Conclusion
Iβve met both Jens AnsΓΈ and Jesper Voxnaes at knife shows in the past. In my conversations with them, as well as some that I overheard, their enthusiasm rang through. These are two knifemakers who sincerely enjoy making epic knives and the Biblio XL is a fine example of that.
Everyone has their favorite knife steel, handle material, etc. Elmax and Micarta are two of my favorites, so I had high hopes for the Biblio XL. But in order for those hopes to become realities, I really needed to put this knife through hell. So I did.
For my first experience with a GiantMouse knife, I am happy to say it was a great one.
Stepping back from my well-informed knife reviewer role and looking at the Biblio XL from the consumerβs viewpoint, itβs a pretty sweet deal. Weβve seen knife prices bounce all over the place in the last few years, so nothing really surprises me.
But although not low, $225 is a stellar price for this premium knife. But donβt look at it as premium. Look at the Biblio XL as an everyday knife you can employ β anywhere for a variety of tasks β and not worry about it falling apart or failing on you.
