Okay, I’ve finally finished the promised review of the new Kershaw Whiplash. The problems I had in getting this review out were mostly due to trying to get a twelve year old camera to work (turned out to be corroded contacts. Duh.). Remember, this thing is old; modern cell phones may take better pictures. Anyway, I apologize for the quality of the photos.

I hope that this review will help give you some idea of just how this knife fits your requirements. I’ve tried to cover everything I could without doing anything destructive to the knife. Please feel free to ask questions if there’s something you don’t think I’ve covered.

Incidentally, the squares on the background grid are 1/2 inch.


Box
The knife comes in a nicely designed box, as one would expect from a reputable maker like Kershaw. I’m in the graphic design business and I’ve designed a few boxes in my time. I certainly wouldn’t be ashamed if this were one of my designs: it’s nicely done. I doubt any of you care about the box though, so on to the knife.

What’s in the box
Opening the box we find that it contains a plastic bag with the sheathed knife, one slip of paper with Kershaw information on it, and a second slip with a few words about the blade coating. Not all manufacturers bother telling you that coatings — all coatings — will scratch and wear with use. Nice touch, Kershaw.

Sheath
Materials:
The sheath itself seems to be a composite of what I’m guessing is a type of ballistic nylon bonded to a semi stiff, yet flexible, plastic.
Construction:
The edges that form the belt loop are turned under and stitched, and there’s a formed plastic channel riveted to the edge where the cutting edge would be. A nylon strap with a heavy duty snap holds the knife securely in place. The strap that holds the knife in the sheath is held only by a single row of light stitching, which doesn’t appear to be very strong. There is a nice little tab with the Kershaw name on it sewn to the outside of the sheath. All in all, it’s a decent, secure, safe sheath for a knife in this price range. Nothing fancy, nothing exotic, but a good, serviceable sheath, non the less — except for the weak single row of stitching on the strap. My personal preference on this particular knife would have been kydex, but I wouldn’t go to the expense of replacing this one, since it is a decent sheath.

Knife
Blade: The 4 1/2 inch (1 3/8 inch thick at its widest point) blade itself has a fairly nice sweep to it up to the centerline, with the point itself pretty much in line with the handle, something that I very much like if I have to use the point for minor drilling of wood around camp. Above the cutting edge is an unsharpened clip point, with an unsharpened swedge going back about half the length of the Black Titanium Carbo Nitride coated blade. The cutting edge of the knife is — how should I put this — a less than a cutting edge. Neither the hairs on my forearm — nor anything else — are in any danger of being cut by this blade. Out of the box, this is the dullest knife I have ever seen, not at all what I would have expected from a company like Kershaw.
Moving on to the top of the .125 inch/3.175 mm thick blade we come to the 1/4 inch deep vertical cuts (6) in the blade. I’m not yet really sure of the purpose of these deep, deep cuts. If they’re meant to be jimping, it’s pretty excessive (with sharp edges) — although, with gloves on, it might be just what the doctor ordered. I must say that, when holding the knife as I would for fine work — cutting notches in sticks or anything requiring good control at the back of the blade — they are perfectly positioned. Just behind the deep cuts is a section of more conventional — and smoother — jimping revealed by an inset portion of the handle.

My brother has been testing one out as well. Hopefully he can add his thoughts to this as well.

Steel: The steel used in this knife is Cr13MoV stainless, also used by Spyderco and other manufacturers. Cr13MoV is a Chinese steel with, apparently, similar properties to AUS-8. As I understand it, it is hardened to around 56 to 58 RC. I’m not a steel guru, so anyone who is should feel free to weigh in on this.
Sharpness: There’s good news and bad news here. Out of the box, this was the dullest knife I’ve ever seen: that’s the bad news. The good news is that once I sharpened it, it was hair-popping sharp: it will take a good edge with a little work. I should point out that the grind on this knife was uneven out of the box, with two different angles, and took a little work to correct with a DMT aligner (fine and extra fine).
Tang: The knife sports a full tang the length of the handle, although its strength may be compromised somewhat by the very deep cut for wrapping the lanyard. At its thinnest point the tang measures only 1/2 inch, which may not stand up to some kinds of very heavy use. The tang also has a choil cut into it of about 1/2 inch radius. Because of the placement of the choil, it adds to the comfort and security of the handle, and aids in controllability of the blade.
Butt: The butt end of this knife has a concave ending with jimping much like the smoother jimping on the top of the handle. I see no purpose for this jimping, other than cosmetics.

Handle: The handle is approximately 1 1/16 inch thick. The scales themselves seem to be molded plastic with an embossed pattern to improve the grip. I should point out that the edges of the plastic scales themselves are a little sharp, but I would think that a few passes with some sandpaper would quickly fix that. The scales are attached with six small pins (and possibly epoxy, too, although I have no way of knowing for sure).
Now we come to the overall shape of the handle, and what has caused most of the hubbub about this knife. Let me begin by saying that the handle overall is relatively comfortable for a flat slabbed handle. I have only medium hands (I’m 5’9”), but would like to have seen a longer handle. The tang of the knife protrudes from the back of the handle to provide anchoring points for the lanyard (more on that later), but is a little sharper than I would like and causes hot spots when holding the knife for work. Because of the deep choil on the bottom of the handle, the knife provides a surprisingly secure grip. So far so good, and if the designers had of stopped there, I think they would have had an instant winner on their hands. Unfortunately, they didn’t, and the next bit is what has stirred everybody up about this knife design: the lanyard, or more specifically, the cut into the handle above the choil for storing the lanyard.
Because of the way the plastic scales overlap this inset, I can’t measure as accurately as I would like, but the tang at that point seems to be about 1/2 inch thick, which is actually a little thicker than I would have thought from the photo. As others have pointed out, there have been many knives made over the years with stick tangs — the classic Marine Ka-Bar fighting knife being just one example — that have proven to be sturdy and durable knives. The difference here being that the stick tang portion is only at the top of the knife along the spline, while a more traditional design — like the Ka-Bar— has the stick tang aligned along the center line of the blade. Is having the thin tang at the top inherently weaker? I really don’t know yet, but I must say that it certainly looks odd. Right now I’m inclined to say that it’s stronger than I thought it would be.

Lanyard
The lanyard itself seems to be a length of 550 paracord attached at the very rear of the knife by passing it through a set of holes, then melting the ends to make them larger than the holes. My guess is that it’s not the strongest method, but if it ever breaks, it should be easily replaceable; just don’t lose the little stretchy rubber tab that’s used to hold the lanyard in place when the lanyard is not being used. The scales on this knife are actually four plastic scales mounted in such a way that they leave a deep channel along both sides of the knife to house the lanyard when it’s not in use, and a rubber tab holds it under tension by looping over a steel protrusion at the rear. It works, but it’s a somewhat less than elegant solution.
Why go to all the trouble to design an entire knife around a lanyard? That’s still a mystery to me, although the designers must have felt that it filled some niche, and apparently Kershaw agreed with them. In my opinion they would have had a far better knife by eliminating the lanyard (c’mon, just drill a hole for it), not cutting into the tang above the choil, and having solid scales on each side. As I said earlier, I think that would have been a winner.

Usage
So, how did this knife perform? Well — because it was so dull out of the box — not very well at all ... until it was sharpened, that is. Trying to cut a fuzz stick with the original edge was a study in frustration. Once it was sharpened to a hair popping edge, however, it was a different story, and it produced nice, tight, tiny little curls. I then used it to whittle a nice sharp point onto the same stick I had used for the curls, and it performed admirably. I must admit that it had lost some sharpness by this point, but a few strokes on a charged strop brought the edge back to shaving sharpness. I then used it to cut some meat and vegetables in the kitchen (forgot to take pictures) and it cut just fine. Because of the thickness and edge geometry of the blade it was actually a pretty good cutter.
I must point out that although the handle feels comfortable in the hand when just holding the knife, it’s a different story once you use the knife for chores like whittling wood. As I mentioned earlier the area of the tang that protrudes from the back of the handle cuts into the hand somewhat, and that very deep jimping is really, really tough on your thumb. Despite the odd look of the handle though, it has an overall good, comfortable feeling in use.
I did take the knife outside and carefully baton (lengthwise) through a 2 x 4. It split the 2 x 4 without any problem. There was no chipping or real curling of the blade during batoning, though it did dull the edge, requiring a re-sharpening. I didn’t have the time to really stress test the blade, so I’ll leave that to other testers.

Overall impressions
Overall, my feelings about this knife are more positive than I would have thought when looking at a photo of it online. I like the blade shape and geometry, and the steel seems pretty good — especially for a knife in this price range. I liked the feel of the knife in use, for the most part, although — as mentioned earlier — the butt of the tang cut into my hand, and the deep jimping leaves a lot to be desired, too: it’s too deep, too sharp, and cuts into the thumb unmercifully. I really have to question why it was made this way. There are still things about this knife that I don’t like— and question the usefulness of — like the whole lanyard thing. I’ve made no secret of the fact that I think they should have lengthened the handle somewhat and eliminated the integral lanyard, thereby eliminating the deep cut for the lanyard wrapping. For the most part though, I like this knife, especially for the price.

I hope you think it's a good and fair review. This is the first time I've uploaded photos to Blade Forums, so I hope I've gotten everything right.

I'll be looking forward to your brother's thoughts, too.
 
Yes, I think you gave an honest review (thanks for the addition of pictures).
Your review is detailed and tries to cover every aspect of the knife itself and how it relates to you.

Good review bro. Thought the pictures looked good enough, but that might be cos im viewing the page on my mobile.
I gotta agree that the knife would have been much better without the cut for the lanyard. I might even have bought one...
Thanks for the review. Good job!
 
Good review dawsonbob. You covered everything!

I haven't used the Cr13MoV steel, but similarities to AUS 8 would lead me to believe that it will take a great edge, but as you mentioned, would need touch-ups more frequently than S30V. But then, it wouldn't be a $ 35 knife. I agree with your assessment about the jimping. In a gloved hand, it may provide some extra grip.

Again, very nice review! :thumbup:

Thanks, SPXTrader. I tried to get it all in, and be fair in my assessment. As far as the steel goes, I did a little minor research for the review. It seems to be a fairly good steel, although in this particular knife it was treated a little softer than I would have liked for edge retention. In use, and during sharpening, it reminds me somewhat of the feel of 1095. It's not as hard as my BK-2, but I could feel similarities, even though this is a stainless.
 
At first I thought this would go 20 different kinds of sideways... but, it was a very nice thoughtful review. The important thing is that you touched on some of the main concerns I had. I suspect you came to the same conclusions I would have.

Thanks for taking the time to do this... after the other thread it really needed to be done and I can't imagine anyone could have done it better. :thumbup:
 
Thanks, spiralarchitect. As you may remember, I was initially laughing at this knife in the other thread, but when several people asked me whether I had actually used it, I had to put my time in to do a decent, fair review. As with any knife, there were things I liked, and things I didn't, but I tried to cover both.

I still think it's an odd looking thing, but I have to admit that — after using it — it kind of grew on me (a little).

I have to thank Hardheart for supplying the knife for testing.

Very nice review. I believe it was a very fair review. I haven't had a chance to fully test mine yet. I threw my back out Friday evening and have been laid up all weekend.
I do have to say that mine was extremely sharp right out of the box.
You had stated,
I should point out that the grind on this knife was uneven out of the box, with two different angles,
That might have been the cause of it being dull.
Which I would not expect from Kershaw either. Although I have pulled $200+ knives out of the box that wouldn't cut anything either.
I look at it as "one of those things that shouldn't happen but did."

Thanks again for review.
I look forward to hearing others' thoughts on this knife as well.

Sorry about your back. Been there, and it wasn't fun.

As far as the grind and dullness of this particular knife, well, it happens sometimes with any manufacturer. A buddy of mine got a Kershaw folder a few years ago that would make your eyeballs bleed just looking at it, so I'm not blaming Kershaw. As you said, these things slip past QC from time to time. Perhaps the shop in China was having a bad day ... who knows? It sharpened up just fine though, which is all that really matters.
 
A customer of mine had a knife (brand name withheld) that wouldn't hold an edge no matter what he did. I sent it back to the MFG. 3 times for him. The third trip they replaced the blades (yes multiple blades) and sent it back. He hasn't had a problem since.

Thanks, bladkersh02. Kudos are always appreciated. I was really worried about the photos, but I guess everyone can see them well enough.
 
Very nice job dawsonbob! I think the review and the photos were very good and both worked together to make it effective. Thanks!
 
Nice solid review.

I know the lanyard has caused some consternation, I was wondering, do you think that the way it attaches would reduce the chances of it snagging on something when carrying it in the field (through heavy brush for instance)?
The design seems like it was meant to make sure you always have a lanyard handy, while keeping it out of the way when you don't need it.

I think the whole point of the knife design was to have a lanyard always available, and yes, I think the way it wraps around the handle would keep it from snagging on brush or other obstructions. I understand what they [the designers] did, although I don't necessarily agree with their solution. As I noted in the review, I think they could have had a much nicer knife if they hadn't designed it around the lanyard. That, of course, begs the question of —if they hadn't designed it around the lanyard — would anyone have bought it; it's the lanyard thing that makes it unique.

It certainly does make the knife stand out. :D
