The Spyderco Yojimbo 2 is a new self-defense knife designed by martial artist and Martial Blade Concepts innovator Michael Janich. The knife debuted at the 2011 SHOT Show with Spyderco founder Sal Glesser delivering a prototype the day before the show. Mr. Janich gave us an in-depth look at the design changes he made to the original Yojimbo to improve the new knife’s performance.
What is the Yojimbo 2?
The Yojimbo 2 has a 3 ¼” Wharncliffe blade of CPM-S30V stainless steel, which is hollow ground. It wears black, textured G-10 scales and has Torx screw construction. The blade is well secured via Spyderco’s compression lock. No MSRP was available at the show, but we were told the much-anticipated knife should begin shipping in the 4th Quarter of 2011. (Editor’s note – The knife shipped on time and is still in production as of the fall of 2019.)
As Janich describes in the video below, the Yojimbo 2 is an evolutionary advancement from the original Yojimbo. The newer knife offers a number of ergonomic improvements including a shorter handle that can improve striking and gives it a different feel in the hand. Janich stated he prefers a Filipino grip so he eliminated the rear serrations to eliminate thumb abrasion.
Additionally, the design has other performance improvements. One of them is that the blade has a hollow grind to improve tip strength. Also, lock strength is improved. The knife uses a compression lock mechanism.
The Wharncliffe design is extremely powerful in a self-defense situation. The 3/4″ or so of blade farthest from the handle has an incredible cutting potential when wielded by someone with just a little bit of skill. I own another Wharncliffe knife designed by Janich – the Blackhawk Be-Wharned – and it is formidable. When you make a slicing arc with the knife, the blade design can be devastating. It makes sense that Janich improved tip strength with the hollow grind.

Interview of Michael Janich
At the SHOT Show, I was able to catch up to Michael Janich at the Spyderco booth. Mike was a gentleman and spent quite a bit of time with me. He also consented to me shooting a video of him with the knife so that he could explain the knife’s features to you.
Randall: We’re talking to Mike Janich here at Spyderco. He’s going to talk to us a little bit about the Yojimbo 2.
Michael Janich: Okay, Yojimbo 2. Of course, the original version of this design was the original Yojimbo that was produced by Spyderco after about 2003 to about 2005 or so.
What I’ve got with this version of it is really try to incorporate some of the design features that I think will make an even better knife. Still has Wharncliffe design. You need the Wharncliffe is when you are moving your arm in an arc to cut, cutting full power on weighted point.
My preferred grip is Filipino grip, top on the back, this has really nice thumb purchase. We got rid of the chipping or the serrations on the back. So that way, I could just slide it on. I’m not going to cost any abrasion on my thumb.
It’s a hollow grind instead of a full flat grind which gives a little stronger tip.
The lock’s got a little bit better overall strength in the blade. Still, the compression lock mechanism is the strongest locks we have and spread it through the line-up.
The ergonomics of the handle overall were even more polished about here, so it feels like hollow on the palm when you grip it, as opposed to the more concave shape for the original Yojimbo design.
The handle is shorter. We’re kind of emphasizing the idea of striking with it. We don’t really need — There’s a longer tail on that handle when we had it before.
And also, can set up to four clips – on the right side of the area.
It’s really good trying to kind of tune-up the ergonomics making the handle a little better; get rid of the abrasive hutch spots and things like that to make it overall, it’s even more compact and it’s pro.
Randall: Thank you, Mr. Janich.
I like the knife designs coming from Michael Janich. They show a significant level of understanding toward the use of a bladed weapon for self-defense. The designs tend to include innovative features with solid construction technique.
The Yojimbo 2 will be part of my knife collection as soon as they go on sale (update: I purchased one the week they went on sale. I’m very pleased with it.) I was happy to get one well below the suggested retail price on Amazon.
My Yojimbo 2 is a great knife, and I’ve been carrying mine for a while now. I whole hardily recommend them to anyone that appreciates a quality knife.
Since the introduction of the Yojimbo 2, Spyderco introduced a fixed blade knife called the Ronin 2. The Ronin 2 is not an exact fixed blade replica of the Yojimbo 2, but they are very similar in design and function.
While the folding Yojimbo 2 will make the more sense for police officers and others needing discreet carry, the Ronin 2 offers a lower price (less than $100) for those who can carry a fixed blade.
