First, a (very) little about myself.

I spent eight years in the army. I spent part of it as an infantry grunt, part of it as an infantry scout / forward observer, and part of it as a scout-sniper. I am NOT some kind of superman by any means, and the military wasn't really for me (hence why i'm no longer there, though I was 100% honorably discharged) but I DO know what I'm talking about when it comes to field gear. NOBODY knows "Will it work?" for stuff like this better than a grunt!


Now, onto something you care about. :)


You've Got Mail....
I received in the mail last week, after applying for a knife testing position, a very formidable little steel spike from Mr. Koster. Right out of the box I was impressed by the little blade.

Like other reviewers, I do not know what steel this is. I was told the prototypes would be either 1095 or O1. I'm no steel expert, so I'm not going to even try to guess which one this is (1095 maybe? Ha).

Here's a look at it (nearly) fresh out of the box. I did NOT clean it, did NOT polish it, did NOT sharpen it...I am reviewing this nice PRECISELY as I recieved it.

Rough looking? Yes. Comfortable? Effective? Well balanced? Efficient? Read on...

The Specs:
The measurements I was given from Daniel Koster were as follows:
3" blade
4.75" handle
3/32" thickness

The measurements are, as these pictures show, accurate.

Here are a few comparison shots. I thought since many of you probably have or have held at least one of these other three knives in the picture, it would give you a better idea of the scale of this prototype blade. The knives pictured alongside the prototype are for SIZE COMPARISON and nothing else. The knives you see are, in order from left to right:

-Spyderco Endura 4 Folder
-Bail Out Bag Prototype aka "Nasty Spike" (I call it this myself, because that's what it resembles...this is NOT the official name given to it by anyone, it's just my loving nickname for the blade)
-Swamp Rat Warden
-Gerber Fast Draw Folder

It's All In the Details...

A few opinions on this blade.

First off, I love the ergonomics of the handle. I could almost use it a LITTLE teensy bit larger, but for the record I have fairly large hands so most people would probably be just fine with current size of it.

As a sidenote, I initially felt that rounded edges on the handle would be more comfortable. The edges on the Nasty Spike are basically 90 degree angles, and tend to bite a tiny bit into the hand if you hold it too hard. However, it was brought to my attention that this makes it a PERFECT handle for striking a firesteel / magnesium block / etc. Why I didn't think of it, I have no idea. However, it was a wonderful point and upon consideration of the Nasty Spike's handle further, I think the hard edges suit it just fine. In addition, it does help provide for a very firm grip on the relatively slim handle.

With regards to the thickness of the blade itself, I love it. I feel it is just thick enough to provide some real power and support and maybe even be used for light prying of some sort (the handle of course would be better for this than the blade), yet it remains thin enough to be easily concealed, easily carried, and easily stored.

I am PARTICULARLY liking the highly aggressive jimping on the back of the blade. The jimping itself is borderline sharp, and provides excellent thumb grip. In addition, it also provides a little less than half an inch of sawing ability. I know, that isn't a lot (hardly any really) but you never know right? I mean, this is a "bail out" situation we're talking about, you use the tools you can get your hands on. It's not going to be a good dedicated saw at all, but it's there if you get the urge. :)

The jimping, along with the ergonomics of the handle, provides a great choked up position for more detailed work. You can NEARLY use the blank space below the actual cutting edge of the blade as a choil, but it felt just a bit too tiny for my hands. Again, I have larger hands than most people I know.

(notice the jimping)

"Is This Sharp?"


Ah, the words no knife seller wants to hear at a knife show. Usually followed by an expletive and potentially a spray of vital fluids.

The edge on the Nasty Spike was very sharp straight out of the box. Could it have been sharper? Absolutely. Some time on the Sharpmaker would've done it just fine. However, was it already sharp enough? Well, you tell me.

"But What Do I Carry It In?"


We were not supplied with any sheaths. Daniel left it up to us as to what we would put the blade in. Myself, I'm not a sheath maker. I have zero leather working or kydex molding ability or skill...never tried either one. However, I found two nice little sheaths in the house that worked just fine for it.

The first is the leather sheath that came with a now-defunct Hibben throwing knife. The fit was a touch off...while the blade fit entirely down into the sheath, I did have to force it a bit. It was however, once sheathed, snug. The sheath only covered the basic portion of the blade though and did not do almost anything for the handle. It most certainly passed the upside down test though (lightly shaken, I didn't swing for the park with it or anything as flying steel indoors is usually a bad idea).

The second that I tried is a kydex sheath that was made for a scrapyard Scrapper 5. No clue who made the sheath itself, but the Nasty Spike fit down into it like a champ and was held VERY well. The sheath held basically only the blade of the scrapper 5 but it held far more of the Nasty Spike, and I felt as though I certainly COULD have given it a good swing and it would've stuck (but again, just a light shake which it of course passed).

In Conclusion:


I am very impressed by the BOB Prototype. It is precisely what Daniel said it would be -- a "down and dirty," "comfy and functional," but not finely finished knife.

The balance of the knife is very good. I found the balance of mine to be slightly off the middle of the knife, between the first and second holds on the handle.

The blade length is good, and the edge it came to me with was better than many knives I've recieved. I have no complaints there.

The handle is good, but I feel could be a bit longer. Just my personal opinion. The ergonomics of it is good, but some may wish to take a file or something to the edges to round them off a bit to take the bite out of it. Alternately you could do a cord wrap. Here is one I did in about two minutes...it was not finalized, and it's not a very clean wrap. Once I began to wrap it, I felt like I really liked it a LOT more without the wrap.

The weight of the knife is negligible -- you almost forget you are carrying this thing. It would make a great EDC knife, provided you find an appropriate sheath for it.



In summary, I believe this knife is everything Daniel Koster set it out to be. It's a functional, solid, beater BOB / EDC knife. It's not going to win any beauty shows, and I don't know that it would stand up to serious bushcraft (but then again, it's not a bushcraft knife...) but it is certainly a great little blade.

This one is going in the "keep it" pile. Or better yet, in the BOB. :)


Writer's Note: Occasional cleanup will be done on this article to correct grammar or rephrase things if I feel like I wasn't clear with what I wanted to say. In addition, some harder tests will be thrown at this knife and results will be posted in this thread. Thanks for reading. :)
 
You should see some harder use pics in the next week, give or take. I have a few days off coming up. :)
 
Sweet!

Great review and pics so far. *Nasty Spike*....love it. :D

Well we finally broke the nasty spike. How, you may ask? We used the tip of the blade to tighten up some retention screws on my marlin 60. Haha :)
 
If I broke from failure I will gladly replace it free of charge - shoot me an email.

Thanks!

Now that is a warranty despite not using it as intended! Another reason why I prefer knives from some our top WSS members:thumbup:

Well, like I said we broke it quite literally using the blade as a screwdriver to tighten the retention screw on the marlin 60. So that was pretty bad abuse...call it failure if you'd like lol, but honestly I was TRYING to see what the blade could take!
 
Good review!

That looks like the knife I've been looking for. I want a small bladed knife with a full size handle, which I'm having trouble finding. Most neck knives are 2 or 3 finger knives, which I know aids in concealment and carry comfort, but I'm looking for one to leave outside of my clothes and to use outdoors. With a minimal sheath it looks like it would be a decent pocket knife, too.

Do you suppose there's any chance Mr. Koster will make a version with his excellent scandi grind on it too?
