Thoughts Regarding the Kershaw Tilt 4001


Through channels, and completely unsolicited, I somehow was graced with what is likely a once-in-a-lifetime opportunity to use and review a very rare Kershaw Tilt 4001. (*see footnote)

So let's get to business.

- - - - -

"The most innovative designers consciously reject the standard option box and cultivate an appetite for thinking wrong."
— Marty Neumeier, Designer and founder of Critique Magazine


The Kershaw Tilt represents to me a breakthrough moment in design innovation at Kershaw. It is tough, nimble, big, light, beautiful, wicked and functional.

When it comes to looks, the Tilt is in it's own class.

It's almost ironic that the company that made Ken Onion's curvilinear forms accessible to the greater public would be the same company that would release Ken Onion's aesthetic antithesis. Gone are the straight-from-the-barrier-reef flowing lines and supple three-dimensional molding. Enter instead a stark, bold, angularity that would seem more at home in a museum's modern sculpture collection than swimming in the ocean.

The Tilt's unique look makes it extremely hard to think of another production knife (or even limited series knife) at this price point that is worthy of comparison. Double or triple the price and you're left only with particular custom makers. This is rarified air, and I applaud the company for it's ambition in pushing the boundaries and daring to make a knife that looks nothing like any other.

But this knife isn't just about looks. The Tilt's technological innovations have been covered extensively before, but I would still like to cover what I consider the chief three:

1) Udderholm Vanax 75. Scores a penny. Curls a steel nail. Shaves arm hair afterwards. I haven't sharpened it because it hasn't needed it yet.

2) KVT (Kershaw Velocity Technology) Opening System. So fast it's scary. But make sure your fingers are clear when you're closing her up. It's fast both ways. I look forward to using the Tilt on my future camp/surf trips to see how this pivot system really holds up. Exposure to salt air and random debris is my biggest concern here. Will the ball bearings seize or slow? I have no answer at this time, and the fast way to find out is to bury it in the sand and then throw it into the ocean and fish it back out. I'm too big of a chicken to do that (yet), so I'll just let what happens, well, happen. Ask me in a year.

3) Frame Limiter Technology. This is the one that really gets me. Knifemakers the world over have devised all kinds of toys and tricks to keep users from overextending the lock bar on their frame lock knives. The most common solution is to bolt an additional piece of metal onto the frame to act as a stop. Others hope the presence of the pocket clip will be enough to deter overextension. Kershaw throws out the playbook and rethinks this problem from the ground up. And they came up with a solution that is as simple as it is brilliant. And it's a all just a matter of geometry. You see, every one else cuts the gap that divides the lock bar from the scale like this - scale ___||___ lock bar. It's always been perpendicular. But on the Tilt, the cut line is cut at an angle so that a cross-section view of the gap between the two is shaped like this - scale___//___lockbar. When the lock bar raises up, it's angled surface comes into contact with the angled surface of the scale and the bar stops dead in its tracks. No additional piece, just additional thinking. Dang. I wish I would have thought of that.

Let's get to guts of the matter. How does the knife function?

The blade: The blade is remarkably thin for such a large knife, and as such has performed admirably for food prep. I didn't think I'd use this blade for that purpose, but the thin, straight, crazy sharp edge, combined with just enough finger clearance makes this knife a go-to kitchen tool. Who would have thought? My love affair with knives started in the kitchen, and my love affair with Kershaw started with Shun, so this pleases me to no end.

For those of you that might be worried that the thin blade might lack of strength, I can only refer you to my note above about the steel. this thing whittles wood, scores copper and tin and even curls a smile into a 16 penny nail. I'm satisfied.

The handle: This is where I have a little bit of an issue. The points at the top and bottom of the handle , and particularly the one near the pivot add 1/2 an inch or more of unnecessary length to the handle. It consumes quite a bit of pocket for a knife with a 3.5" cutting edge. Both the original Volt and my 4" Darrel Ralph offer more cutting edge for a lot less handle bulk than the tilt.

But the handle does come with a few benefits. First is the finger clearance mentioned above. You'll have a lot less knuckle rash when making scoring and pushing cuts with the tilt.

The large handle of the tilt also offers multiple hand positions. My favorite position for hard use is to grip the bottom half of the handle with the bend at the back of the handle fit into the crook of my thumb. This position gives me a great grip, while keeping my hand far away from harm.

The double choil or finger grooves give you plenty of grip for choking up and doing detail work.

I'm only a couple of weeks in, but so far the lockup has always been incredibly tight, but not so tight as to make the release difficult to manage.

I wanted to speak a moment about the Tilt and also about my favorite Kershaw to date, the original Volt. These knives both likely cost more to design and make than they likely ever will generate in income. I hope this never discourages the powers that be over at Kershaw from pushing the boundaries and releasing these knives to the public. If anything, these two knives in particular were priced $100 less than they are worth at the outset. I thank you for taking the time and bringing your two finest creations to date to us, money be damned.

Well, that pretty much sums it up. I'll leave you with one final quote, and I'd say the most important one when I think of the Tilt. Thank you so much for your time and comments or questions (if you have them).

"People think that design is styling. Design is not style. It’s not about giving shape to the shell and not giving a damn about the guts. Good design is a renaissance attitude that combines technology, cognitive science, human need, and beauty to produce something that the world didn’t know it was missing."

In full disclosure: this knife came to me in part because it did not pass QC at the factory. It is marked as serial number 073, and while it was not marked with the signifying XXXX, it was clear right out of the package that it is a blem. Specifically, the spine side of the titanium scale is clouded as if it were splattered with a solvent of some sort in the factory. Or perhaps a contaminant was not completely cleaned off before the titanium was anodized? Hard to say, but the blem is strictly aesthetic and only noticeable on inspection. Another small issue was that the lanyard tube pin at the end of the handle was not fully seated, causing a very slight flair between the scales. One quick tap with a soft mallet and it fit perfectly, leaving the finish flaw as the primary blem.

But this is all trivial and I did not want to bog my review down with this information.
 
Great review and thoughts! Any chance of some pictures of the "blem"? You have me curious...

I'll try to get a couple of pics up this weekend. The blem is only visible when the reflection is right, so I might not get a pic of that.
 
Thanks for the excellent review. Can't wait to get my hands on my as yet unfulfilled pre-order.
 
It is a great knife. It has been the only knife in my pocket since I got it. It never really leaves my side.
 
That was perhaps, the most eloquent knife review that I have ever read. Very well done, LA.
 
I fondled one locally today. I was underwhelmed, after all of the praise I had read. My first ZT-0551 was a good bit less expensive - and better appreciated. I grabbed the one I carry in my back pocket - and it made me smile. My second one - aka a 'backup' - was even less - a real bargain, by comparison. I passed on the Tilt - and it's neat little bag. It's blade metal reminded me of something my first bride took to mellow out... actually made her more mean and hyper. My ZT-0551's El Max, on the other hand, made me think of Mexican lunch - and away my second bride and I went for lunch! Just out of curiosity, what should the Tilt cost? It seems like the one I saw said $270.

Informative review.

Hi LA -

Nice review.

Have you had any opinion on the clip?

I have been carrying my 4001 every day since I received it, including on a week-long driving vacation. I am thoroughly impressed with the knife.

The pocket clip is a real scratch-maker! I gouged up the steering wheel on my wife's Impala three times leaving deep tearing gouges, I did the same to my truck in one place, and I have scratched up the stalk end of the seat belt in my Corvette with this clip.

I also put a large, long scratch down the plastic interior piece on a friends Ford.

All that said, the clip has not been bent at all - so it is definitely a robust piece - just be aware of it's ability to mark up anything the sharp edges come into contact with!

best regards -

Thank you for your honest review, LA. I really enjoyed the thought-out quotes and how you went in depth into the many aspects of the knife. It's rare to see a review detailed on this scale.

I can't wait to get mine!
 
Great review/thoughts on the Tilt -- thanks for taking the time to put that post together. :thumbup:
 
Thanks so much for the review, very informative. Glad to see that you use quotes throughout multiple disciplines of design, because the concepts behind good design is to an exceeding extent, universal after all. Can't wait to get a hold of a Tilt.
 
Great review. It would be great if the KVT ball-bearings and Frame Limiter technologies could be employed in future mid to high ned Kershaw and ZT folders. These two seem promising technologies.

One question, how does the KVT compare to nylon, phosphor bronze washers and IKBS ?

Feels just like IKBS. I have an IKBS knife and you can't tell a difference.
 
Thank you to everyone for your comments.

mqqn, are you wearing your tilt in your back pocket? I can see the edges of the tilt gouging some things on occasion, but I wonder if it's causing more damage for you because of the force of sitting on it or something? Just curious.

That said, the clip is my second least favorite part of the Tilt behind the oversized handle. The clip is very cool looking and fits the design of the rest of the knife very well, but I find that it is difficult for me to draw. The clip if anything is too tight for my tastes. On some knives, I grab the end of the clip and lift it up to make drawing the knife that much easier, and even doing this, the Tilt's clip is hard to get a finger under. I can see how the corners can dig into something on contact, but I think that's a problem with almost any clip, not just the Tilt.

Mesoscopic, I am not a good judge of the different pivot technologies available on the market. I've found that every knife is different, and a tight and heavy knife with bronze washers can be sluggish compared to something like the Leek. It's all a balancing act. I recently acquired a Tyrade for my collection and was frankly shocked at how slow it is. in the end, I just know what knives are fast and smooth by feel, and the Tilt is among the fastest and the smoothest.

Now, this might be crazy talk, but I would love it if it KVT were combined with a spring assist technology of some sort. This isn't just about throwing the knife open, I actually would very much prefer some sort of resistance when folding the knife closed. She's almost bit me twice, once on my thumb and once on the heel of my hand. Adding some sort of resistance there would be a great help.

Here are a couple of photos, starting with a view comparing blade sizes and handle sizes.

In order of longest handle to smallest, from left to right:

Kershaw Tyrade 1850

In these photos, the only knife that has a handle longer than the Tilt is my Darrell Ralph HTM Mad Maxx with a 5.5" blade. The Tilt by comparison has a 3.5" cutting edge. That's two full inches difference in blade, but less than half an inch difference in handle length. The smallest and lightest of the set is also a Darrell Ralph, and even it has a longer cutting edge than the Tilt.

So that's the downside of the handle configuration. Let's focus on the upside:

For a knife with so many straight lines, the ergonomics of this knife is astounding. And the multiple hand positions (the one above being my favorite) and the finger clearance are really great. But let's not call it finger clearance, because a knife with finger clearance is not that impressive. Let's instead call it FLIPPER clearance. This is the only flipper knife I can think of where the cutting board picture above is even remotely possible. But the flipper is still there and works beautifully.

Hi LA -

I am carrying the Tilt in my right-front pocket. When I get in and out of my Impala, the clip, when the knife is pushed all the way to the right side, can rake across the steering wheel. I have resolved the issue by moving the knife towards the leftmost side of my right pocket before I get in and out of my cars.

I think it is just that this clip is squared-off, and it is very strong as well. All of my other clips have a rounded edge on them which would tend to deflect contacts, whereas the Tilt's clip wants a piece of whatever it comes into contact with.

Not a problem for me, I have resolved the issue by being aware of the clip's position in my pocket.

I love the knife, and as you have noticed, it could easily bite you on closing if you are not very careful.

I still have not carried anything else since I bought the Tilt (save for one "dress up" day when the Sebenza came out), and that is testimony to how good this knife is.

Thanks for the comparison pictures.

best regards-

LA, really appreciate your review. It's obvious you have a eyes that capture what many don't recognize. Hope the piece gives you years of appreciation.

To go slightly into the handle design aspect of which you were less pleased with, I have to offer up the flip side of blade/handle ratio. Personally, I'm real big on uniformity, and balance. It's what triggers me when I see a knife. I feel your "downside" comment with regards to the Tilt and it's handle.

I've tried over the years to evolve with my understanding and appreciation of design, forcing myself to swerve off that perfect road I am so attracted to. It was important to me to experience different scenery, and to feel the why's of this foreign path. I tried to share the eyes of the mentors around me, and from those that were comfortable with this "less than perfect" appearance.
I remember Sal many years ago schooling me on the subject of ratio, and then years later posted on the subject:

Just another opinion, but, Handles are for holdin', blades are for cuttin', looks are for showcase queens.

Would a scalpel perform better with a larger blade or a smaller handle?

Does a 14" machete need a 14" handle? Efficienty is in doing the job, performing the task safely and comfortably.

I have to hold 3" handle like a teacup. Purchase is more imporant than appearance to me. I don't "ooh" and "aah" over my knife's looks after I cut something.

16 oz hammers and 13oz hammers usually have similar sized handles.

I can appreciate those that put appearance before anything, or their "sense of balance" requires "proper ratios", but tractors don't have to look like Ferrari's and Ferrari's are lousy at 4 wheelin'.

These thoughts come from a place that I wanted first hand knowledge of. It expanded my horizons, and the perspectives that came from embracing different/odd, and brought me to where and who I am today. I'm now able to have long conversations about the complexity of design, conversations that keep from being repetitive. We can push ourselves in directions that keep us progressively growing. To go extreme on either side of this coin is to ones detriment IMO, and keeps individuals from full understanding.
We all can become more diverse by not getting stuck with the routine of what just looked good and felt better to me on the inside. I'm afraid it would have made me bit boring and kept me from fully appreciating many of life's alternative routes should I have stayed sheltered.

As I mentioned in an earlier thread, the Tilt is very a very personal piece for me, and there were reasons it is designed as it is. Those reasons need to stay private, but our mission was accomplished. :)

Just a few thoughts from my perspective on the Tilt, and design in general.

Again thanks for the fine review, and unique perspective. Enjoy your knife.
