Founded by master designers Jesper Voxnaes and Jens Ansø, GiantMouse is one of the best names in knifemaking today. While I wouldn’t deign to tell GM how to design, develop and produce its top-notch cutting tools, it does appear that an outside perspective can make for a bountiful harvest.

At least, that’s what I’ve gathered from the brand’s latest collaboration — a team-up with a mainstay of the Detroit design scene. But don’t take my word for it; see for yourself how the Shinola x GiantMouse Brass Perlage Knife takes one of GM’s best designs and makes it even better.

Bleecker sweet

It’s a bold, perhaps audacious claim to suggest that GiantMouse needs help from anyone to make a good knife better, but I do believe it in this case. That said, it doesn’t hurt to have an excellent base model to start with.

This knife is a reinterpretation of the GiantMouse Bleecker, perhaps the brand’s best take on a gentleman’s folder. As such, it shares much in common with its existing siblings.

For instance, specs-wise, it has the same 3.26-inch trailing-point blade and 4.14-inch handle. Together, they measure 7.43 inches — precisely in the sweet spot for EDC. The knife is also slender and relatively lightweight, making carrying it an even simpler prospect.

It also maintains its large thumb hole for ambidextrous manual deployment, spine jimping for a little extra grip and leverage, reversible wire pocket clip and classic, reliable liner lock.

Slender slicer

All the existing features are well and good, but they aren’t what sets this knife apart from its predecessors. Rather, the big differences can be found in its materials and finish.

That slender blade, for instance, is built from Böhler M390 super steel. Directly comparable to MagnaCut, M390 offers outstanding wear resistance and corrosion resistance. It’s also a classic top choice for high-performance knives.

But the most eye-catching upgrade found here is the knife’s handle. Instead of carbon fiber or titanium, this one gets a gorgeous, glimmering custom brass. Better still, the metal has been given a special perlage pattern finish inspired by Shinola’s history of watchmaking.

While brass may require a bit more care than the knife’s other available handle materials, it certainly wins points for its beauty and sheen. And here’s another little tip: if you don’t want to fuss with cleaning it, you don’t have to. In fact, you might not want to, as it will acquire a patina unique to your experience, adding a touch of personalization over time.
