A larger riff off its popular EDC option, GiantMouse’s Biblio XL is proportioned to tackle more.

Is bigger better? GiantMouse is betting so with its first release of 2024. As it’s easy to surmise, the ACE Biblio XL is the big brother of the ACE Bibilio the company released a few years back, but not enlarged to asinine proportions.

My gander at the knife, it certainly hasn’t been up-proportioned to the point it isn’t a viable EDC option—especially for those who appreciate a larger blade. Yet, the modified Wharncliff’s larger dimensions have the potential to provide more utility for certain users. In my mind, the Biblio XL has a bit more advantage over the smaller original as a work knife or even in outdoor applications.

So exactly, how much bigger is the new variation than the original Biblio? Not much—a mere fraction of an inch. But the nearly half-inch GiantMouse has added gives the XL a blade length of 3.2 inches, plenty of cutting edge to tackle a fair range of jobs. As for the overall tale of the tape on the knife, its overall length is 7.6-inches open, 4.4-inches closed and 3.9 ounces in weight. As mentioned, definitely not an option that will weigh you down, nor feel like you’re toting a rock in your pocket.

The blade of the Italian-made knife comes in two steel options. On the Micarta-handed version, Elmax is the order of the day. On the titanium-handled model, Vanadis 4 is used. Both are high chromium-molybdenum-vanadium alloys, with good attributes for top-shelf EDC knives. As to the profile, the Wharncliffe has a bell to it, giving it better-slicing abilities than a knife that stuck to the traditional formula of this style of blade. Adding to this capability is a full flat grind.

Interestingly, GiantMouse integrates a fairly substantial choil into the Bibilio XL’s design, enough to use it as a leverage point on finer work. Additionally, the is understated jimping on the spin—just before the thumbhole—perhaps just enough to add more purchase when utilized, but not so much as to catch on clothing coming out of your pocket. As for action, a ball bearings pivot mechanism deploys the Bibilio’s blade quickly and very smoothly. Aiding in the opening are both a nicely textured kicker, as well as a thumb hold near the spine.

Finally the handle. As mentioned, there are two options—micarta and titanium—both well textured and proportioned to the hand. GiantMouse includes a wire pocket clip, situated for tip-up carry, but reversible making it friendly for righties and lefties. As for cost, the Micarta ACE Biblio comes in at $225, while the titanium model demands a premium of $285.
