Since I use an inverted-edge method, I like to have good power on my pull cuts and back-cut strokes and this blade shape seems to best give me this attribute without going for a Wharncliffe. A decently belly for good bite when I thrust under a limb and pull cut is a bonus, but not a requirement.

I have a large-size palm and XL-length fingers so I like a slightly convex handle shape with a width of at least 5/8" or so. I'm not too worried about a choil or a finger guard despite my largely point-driven method as I largely go for soft targets. A solid, convulsive hammer grip combined with a good scale material will keep your knife planted just fine regardless.

I also look for a good one-handed opening method. Since we're talking Spyderco here, that's pretty much guaranteed and my EDC Benchmade Griptilian 550HG has a licensed SyderHole (which was a major selling point for me, btw.). I prefer the hole to the thumb stud that Mr. Janich prefers as I have very shallow print ridges (made my fingerprinting for my CHP a real dream, I've got to tell you) and have trouble getting good purchase on studs sometimes. The hole means I'll need my thumb tip to suddenly shear off during presentation before it won't grip so that's what I prefer.
Excellent example of a concise, well-reasoned summary of one's approach to tactics and how that approach influences tool selection.

Thanks, psychophipps!

BTW, I actually prefer holes to studs and always have. Most of the designs I did for other companies ended up with thumb studs by their choice, not mine. In fact, the very first folder I designed (the Ramp-Opening Combat Knife--ROCK, which became the MOD Tempest) had no hole or stud. It had a "ramp' that replcated the contact area of a Spyderco hole without the full hole. It was convex to complement the arc of the thumb's movement and avoid any conflict with Ernie's Wave. Unfortunately, when Microtech prototyped it (Microtech was originally a ful partner in MOD), they saw fit to change the design to make the ramp concave. That not only tore the crap out of your thumb, but violated Ernie's Wave patent. Soon thereafter, the knife had a stud.

That's the "hole" truth...

Again, thanks for sharing your insights.

Stay safe.

But I failed "Playing nice with others" in Kindergarten and went on to some success in a law enforcement career--where the customer is always wrong :D .

Seriously though, for those interested, I will add my thoughts regarding the "hardware" (blade) side of the matter. First of all, choice in hardware, if made intelligently, should depend to a large extent on the "software" (training) that you will be using. Legal issues as to blade length, type of knife allowed for carry, and other issues also apply. Body type, personal preferences, availability of the knife in question in your area, budgetary considerations, and other things also become part of the equation.

For me, with my training and experience, body mechanics, body type, and particular situation it works out something like this:

1. If I absolutely knew that I would be in a knife-on-knife confrontation, I would be carrying my Cold Steel Laredo Bowie, Spyderco Rock Salt, or other large fixed blade that I have practiced with and which fits my style of usage and abilities. I have, in fact, been known to carry a very large knife on my person from time to time, though usually due to the writing of a magazine article about that particular style of blade than as a "primary defense tool." I do not have to worry about legalities and style of knife issues at present. Since I am issued and carry an automatic weapon and am a federal law enforcement officer, no one is really going to be concerned overly much with what blade I am carrying concealed.

2. Just as, "in the real world," a lot of large handguns get left at home and smaller firearms are carried, most people do not carry the "monster" size blades. I often carry knives with blades of four inches or less. My normal attire for work is either suit and tie or full tactical gear. If the former, blades are usually not overly large, while, in the latter case, usually at least one blade of 5.5 inches or more in length is present.

3. I believe in using both the edge and the point of the knife. Sometimes a thrust and "cutting out" is the best "defang the snake" motion. In a life and death struggle, I will hit my opponent with what is available, when it is available, and try to target all of my strikes well. In a moving, twisting, sweating, bleeding situation, this is not easy, but becomes less difficult the more you do it for real and the more you practice and spar. As for blade shape, since I use the methodologies of Albo Kali Silat, which includes wrist articulation during many cuts, I get very good results with a curved or upswept blade. I also do well with other shapes. I have been satisfied with the performance of the Spyderco Kris, Emerson (American Tanto) folders, Spyderco leaf shaped blades, and various clip point or Bowie styles from Boker, Cold Steel, Spyderco, and others. To me, hawkbills are great utility knives. Except for karambits, or those hawkbills that have such a gentle curve that some would say they are not a true hawkbill at all, I do not advocate them at all for defensive use. I can utilize a highly curved hawkbill effectively, of course, but would normally use such a knife primarily in a reverse grip, edge out methodology in order to bring the point into alignment with the target without excessive flexion of the wrist. In this grip, I basically have a knife with the limitations of a karambit (range, etc.) but with none of the advantages (ring for retention, extensions, etc.).

4. For me, the knife is not even close to my primary mechanism of defense. Daily, I carry a lot of gear, including a handgun and extra magazines. I have been assaulted with impact weapons, hands and feet, knives and firearms. For private citizens and law enforcement alike, I have to say that there is a much higher probability that you will need to use empty hand techniques, in situations that do not warrant the use of deadly force (using a knife or firearm), or in deadly force situations where you often must use empty hand techniques when caught "behind the curve" and you must defend from an attack while either gaining distance, deploying your defensive tool(s), counterattacking your opponent, or doing all or most of the above. There are times when a knife is preferrable to a firearm, but my primary defensive tool is my training, followed by my handgun, then other equipment. Offensively, as when making a planned arrest, entry to a building (dynamic or slow methodical), and the like is a different story. At that point a long gun (in my case MP-5 or M-4) is primary, and all kinds of other tools are available.

5. Folders are nice for ease of carry. I have a lot of folders, like many of them very much, and would not feel ill equipped if they were all I had. However, in general a fixed blade is stronger and is faster to deploy. I carry a fixed blade at almost all times. For what it is worth, my constant companion in "suit and tie" mode has been an Emerson Fixed Blade Karambit for the last few years.

I encourage everyone who has a knife that they may use for self-defense to do some actual cutting and/or thrusting (depending on your preferred methodology) in meat and various other mediums. Personally, since meat can get a bit expensive and messy, I have been doing a bit of cutting into martial arts matting materials, as shown here in a video http://www.albokalisilat.org/khukuri.html
and here in some still photos from a magazine article
http://www.albokalisilat.org/PDF/large_ ... rticle.pdf
Doing your own testing, with the way that you move with a blade is imperative if you are going to find out what works best for you. Use expert opinions as a guideline, train hard, practice with your tools, and make your own intelligent selection.

I apologize. For some reason I remembered you mentioning somewhere that you liked thumb studs. Of course, you were working for another company at the time and on their nickel so I might have slightly mistook the content of the comment for something that it wasn't. Thank you for being understanding in this regard, Mr. Janich.

As an aside, I have been looking at your YouTube videos as of late and must say that I am finding them very informative and educational. Perhaps a deeper look will be necessary in the near future as my financial situation stabilizes. Thank you again for your insights and the great description of the design to production process of your first knife model.

I don't mind studs but quickly loosen the pivot and oil them so they rocket open. Holes give superior control in my mind (especially when closing).

No apologies necessary, but thanks.

Thanks also for the kind words on the YouTube videos. I'm glad you enjoy them and find them informative.

A knife should be portable enough to always be with you, legal in your jurisdiction, solid enough to survive a fight, and feel right in your hand. The purpose of a knife is to cut, so it has to do that well.

If you train enough, you will know what you want. I prefer a generalist approach, but different styles may be optimized for a particular blade. While I am not a fan of, say, the pikal grip or the kerambit, I respect the specialists who are very, very good with them.

If you do not train, buy a knife designed by a close combat expert who knows more than you do. A knife with Janich etched on the blade will solve your problem as well as it can be solved.
