Created by Michael Janich, the MicroJimbo takes the iconic Yojimbo 2 design but in a smaller form, making it more legally and practically usable for everyday carry (EDC).
This piece is a true jewel. With an MSRP of $300, it ranks among the most expensive Spydercos when measured by cost per millimeter of edge: just 57 mm. That’s a scale of value I may have to start considering. On the Microjimbo in 15V, for example, each millimeter of edge comes to $5.26, whereas on an Endura in VG10 it’s only $1.56 per millimeter.

Of course, CPM 15V is costly, and two signatures on the blade mean royalties. It’s a jewel, yes—but also a gem in its own right.
No disclaimer on this one, as it was bought by myself at Lamnia in Finland for 237 euros. Great service and it was delivered in France 5 days later.

Action wise, the detent on mine is quite strong, with no lock stick, and the blade drops freely back into the handle. This little folder practically oozes quality.

Compared to my Yojimbo 2, the Microjimbo features a full flat–ground blade with a distal taper—very reminiscent of the first Yojimbo in that regard but with full-flat-ground Wharncliffe style blade, roughly 2.45 inches long.

It is made of Made from CPM-15V, a cold-work tool steel with nearly 15% vanadium, prized for insane wear resistance and edge retention.
The blade is heat-treated using a protocol developed by Shawn Houston, further enhancing its performance with a HRC of 65 (more or less but that’s a lot !).

Ambidextrous, tip-up carry only for the MJ and its reversible deep-pocket short wire clip.

It is equipped with Spyderco’s reliable Compression Lock.

The 3.7 mm thick, stonewashed blade is a beauty—short, sharp, and full of character. The edges aren’t perfectly even toward the tip, but that doesn’t bother me; sooner or later it will be convexed anyway.
After just a couple of passes on leather, the Microjimbo was already delivering a crisp, razor-sharp edge, effortlessly shaving arm hair. And for once with CPM-15V, I was pleasantly surprised at how well the steel responded to stropping.

In my CPM-15V family this little folder is not the one to underestimate.
That blade shape as proven to be incredibly powerful.
This knife feels like Lotus Seven equipped with a V8.

The Microjimbo 15V, with its self-defense pedigree, actually falls into the same MBC category as the Lil’ Temperance. With such a compact edge, it’s more of a last-ditch option—a tool that could still deter a threat. It won’t reach vital organs, but it could sever an artery. That said, knives remain one of the worst possible choices for self-defense in my book.
Knives are ambush/backstabbing weapons.

Another last-ditch, highly capable small folder is the Chaparral Serrated. Its serrations can be extremely painful—an advantage in self-defense situations when you need to break a hold and get away.

Remember: 1 – Run, 2 – Hide, 3 – Fight.
Fighting should always be your last option!

For three times the price of a Metropolitan, you get the same edge length but in a heavier package. Once in hand, it feels remarkably secure—despite having neither guard nor choil—almost like holding a small fixed blade.

Another comparaison shot: the Lil Native convexed by Jan Dirk feels much smaller and stubby than the Microjimbo. But on the picture there is no real difference. Both are reliable lil’big knives with strong blades and strong locks.

There’s no jimping on the handle or the blade, yet indexing the knife is effortless. You always know exactly where the edge is, allowing for precise, controlled cuts.
That G10 definitely leans toward the pocket-shredder side.

I prefer my G10 with a smoother finish, so I used 400-grit sandpaper to tone it down—taking care to avoid inhaling the hazardous G10 dust.

I’m able to carry the Microjimbo in my watch pocket. I appreciate the strong detent—it keeps the blade securely closed while in my pocket. However, because it’s so strong, it’s difficult to open with any finger other than the thumb. No easy Spyderflick on this one.

The Microjimbo isn’t out of place on the kitchen cutting board. In fact, this will likely be its main battlefield, as I use my pocket knives extensively in the kitchen. I do need to be careful, though—its pointed tip tends to catch the flesh with a predator-like hunger.

Once razor-sharp, I haven’t been able to dull any of my CPM-15V blades so far, even after cutting cardboard and other abrasive materials. I’m glad to carry such a compact yet robust folder as I continue to explore this remarkable alloy.

Michael Janich has clearly done his homework on this little knife. Designing smaller blades is always tricky, and this one is a pure gem. The choice of a full-flat-ground blade is fully justified by the placement of the Spyderhole, and the geometry remains uncompromised.

I’m looking forward to putting this little knife through its paces.
