Lots of interest in the G-10 S30V version of the Kershaw Ken Onion Leek.

This is the matte/grippy version - ie: the regular full production knife Model # 1660G10

The Kershaw Leek is one of my all time favorite knives -
I like the Leek so much that I have three (well, ok 3 different versions) -

Kershaw Rainbow Leek - a pictorial review

Black "boron" Leek

........ now 4 :D .

Twice already the Kershaw Leek met or exceeded my expectations - read the previous reviews to see what I mean.

So how does this much anticipated full-production G-10 S30V Leek do?

Compared with the regular all steel Leek -

Closed -

LeekG10S30VclsBk.jpg


OK same familiar size and shape - it fits me real well - the G-10 feels really grippy and almost to the point of being rough - but gives LOTS of confidence that it will not slip - almost no-matter-what......

Being G-10 the knife is noticably thicker than the all steel versions -
LeekG10S30Vspn.jpg
LeekG10S30Vthick2.jpg


However it is still very much in proportion and does not look or feel too thick. In fact it probably is more in proportion - because it's the all steel Leeks that are actually slimmer than the norm.

Being thicker the thumb-studs are now pretty much unusable, since they are well below the level of the scales - it's not a big deal since I and most others use the index-open/flipper. Even though they may seem now even more superfluous, one should not remove the thumb-studs as discussed before they act as the stop-pin for the knife (see first review link at top of this page for a detailed explanation).

The G-10 edges are very nicely finished all the corners are very nicely rounded.

A small but practical point - because the G-10 is so grippy to the point of rough - I found that clipping the knife to the pocket actually pretty difficult - especially to fleece type material. This may also cause long term wear problems on the pocket(s).

The other major difference (other than the materials) is that the G-10 Leek is a
Liner-Lock vs. the Frame-Lock of the all steel versions -
LeekG10S30Vlck.jpg


The liner - just fully on the blade tang - I would have prefered the liner to be over a bit more to perhaps 1/2 way - however others may prefer this as it allows more room for wear.

When I did spine-whacks with a newspaper covered table edge - it passed fine - with no hint of release, or any damage - other than the dings in the newspaper padding....

The other attraction obviously is the use of the "premium" S30V steel -
LeekG10S30Vblds.jpg

S30V is etched on the tang.......
the stone-washed finish (sometimes call cracked-ice finish) is very nice and attractive - it seems a very sensible finish that combines attractiveness with the practicality of not showing wear/scratches easily.

So does this S30V steel blade cut things better......?

It slices free hanging paper fine....

Looking at the close-up photo of the blades above carefully - one can make out that the bevel of the edge seems narrower on the S30V blade - the actual edge has a less acute angle than the regular all steel version.

This probably means the S30V edge will last longer in use -
not only due to the steel itself -
but because of the edge geometry.

BUT -
LeekG10S30Vlcbrd.jpg

my ad-hoc cardboard cutting shows that the S30V blade cuts less deeply than the 2 all steel versions I tried - both of which have visibly more acute edge bevels.

However it would seem as if Kershaw may have deliberately put a more obtuse edge on the S30V Leek blade to ensure that the edge will last noticably longer than the plain old 440A blades - but at a possible detriment to actual cutting ability.......

For me this is not a big problem - as I can easily reprofile the edge bevel - probably rolling and getting rid of the hard shoulder between the edge and the blade face - almost convexing the edge.

I really like the G-10 S30V Leek - it's now my fourth Leek and a worthy one because of the "premium" materials used -

However life is full of trade-offs - going G-10 S30V means -

- going from a Frame-Lock to a Liner-lock
- less slim - but some may prefer the the more substantial handle to grip
- very grippy - but may be too grippy causing some difficulties clipping to the pocket.
- S30V should hold edge longer - so the more obtuse edge bevel probably was not necessary - as it cuts less deeply compared to my regular Leek(s) 440A blades.

hmmm the G10 leek looks fantastic. Thanks for the review. I also didn't realize the steel leek was a frame lock. I own the scallion. I'd pick this up right away if the legality of the speedsafe didn't make me nervous, which it does unfortunately. I've been leaving the assisted openers and axis locks at home more and more.

i love kershaw though, these are great quality knives, well made, incredible value.
 
Thanks Vincent. Good review.

After owning the polished G10 Leek I don't think I want this one due to pocket wear.

Plus more and more LEO's are not happy with Assisted Openers.

I REALLY REALLY wish Kershaw made a G10 S30V Leek with manual opening and larger thumbstuds. :(

The polished G-10 with rubbed satin finished version is very nice - almost a handmade knife at a factory price. It is a limited production of I think 1,000.

I mentioned this before it reminds me of the Kershaw Ken Onion Ricochet.

I haven't kept up-to-date with the knife laws. But as far as I know the Federal law has not changed recently regarding switchblades - and as Kershaw takes a great deal of effort to point out (correctly) the Speed-Safe assisted opening clearly falls outside of the Federal definition of a switch blade - so it is Federally legal.

However each city/municipality/state can have different laws. However I haven't heard of any that have changed to make assisted opener illegal.

Each individual LEO has some discretion in their work - and they can make life difficult if they so wished on assisted openers - but that is clearly not the law.

I'd be very grateful if you can please help clarify what you said - especially if you have references to changes in the law (Federal, state, city municipality) on assisted openers? Or if you know of any law enforcement department official or even unofficial policy that's targetting assisted openers.

Thanks.

There are numerous (other brand) manual openers that use G-10 and S30V. Kershaw's selling points are that they make great assisted openers that are legal. Unless there is a huge demand for a manual version, or the law out-laws them, I really think it's very unlikely the Leek will be manual.

Nice knife, clean design, it is too bad that they increased the edge profile. S30V is hard to grind, if anything you need to reduce the edge profile to keep ease of sharpening high.

I believe that any assisted opener in my city is illegal.

Thanks I have seen your thread -

However as most of the responders in your thread have pointed out Speed-Safe assisted opener does require MANUAL opening of the blade before any assistance takes over.

Here are photos showing the amount of stand-off of all 4 of my Leeks, to show how much the blade actually has to be moved before the torsion spring kicks in.

Of course it's where you live - so you're very wise to err on the side of caution on how you interepret the law.

Like you, I self-restrict my carry of assisted-openers to my home/property - just to avoid any possiblity of hassle -
even though I believe them to be legal where I live -
good evidence of this is the easy and open availability of the Speed-Safe assisted openers in my local WalMart and other stores......

Thanks for your input.

Vincent,

Thanks for the info. I'm starting to think maybe I should just not worry about it and just carry one if I want. It's not like I'd be "looking for trouble". Plus you're right, I could always use the phrase... "Well I figured since I got it at Wal-Mart it was legal". :)

I don't even know if anyone would hassle me if I was behaving.

:)

Ah! many thanks for your valuable input Cliff -
always a pleasure to hear from you in reviews.

Yes, I was kind of taken aback by the edge profile - with a "premium" steel like S30V it would seem as if they could even go for a more acute (sharper) angle -
although I must admit that the 440A edge angles are pretty acute already - that's why Kershaw has a reputation of producing knives that are very sharp out of the box.

This is almost like the expression of "belt and braces" (Brit talk - "suspenders" in US talk) - ie: a double cautious move - to ensure the S30V will hold its edge noticably longer than the regular 440A....
as if there is going to be any doubt.
...or is there? :p

How quick is the assisted opening of the G-10 S30V Leek?

Compared to the original all stainless steel version Model 1660 - this G-10 version feels faster.....

It's not quite as fast as the titanium oxide coated Rainbow Leek (1660VIB) - which feels slick in the hand and almost "jumpy" or "too fast"(!) - but nonetheless impressive.

This G-10 version feels about the same speed as the polished black "boron" Leek (1660BLK) - which seems to me a really good balance between speed and control.

Note: this is all relative - even the so-called "slowest" regular 1660 Leek is pretty d*mned fast - it's just that in comparison my Rainbow Leek makes me go WoW! and jump back a little. All this is pretty minute.
(I have adjusted the tension of the pivot screws to what I consider the right balance between no play in the blades and quickness in opening)

The respective etched dates are:
regular Leek - Dec/02
Rainbow - Jun/03
black "boron" - Nov/03
G-10 - Mar/06

So it seems to me like a steady improvement/refinement of the Speed-Safe assisted opening mechanism by Kershaw -
and probably took about a year from the introduction of the original Leek to get just the right balance.

I like that thought...... :)

Terrific review Vince, thank you kindly.

Just received the textured G-10 Leek from NG.

WOW! Stunning. The leeks keep getting better. I was not prepared for this level of perfection from a $90 knife.

Grippy surface, fast opening, perfect lock-up (open and closed), very sharp and pointy, black clip (off to Kershaw to have the clip reversed for tip-up), lock works securely, stone-washed blade doesn't show finger prints and looks business-like, black screws and black spacer add to the gothic look, light weight and yes it is thicker and this gives a solid gripable girth.

Could muscle the Mayo TNT from its current pole position.

I recommend it. Thank you Ken Onion, Kershaw and New Graham.

Best,

oregon
 
Nice review Vince. One note though, thinner edges should hold its edge longer than more obtuse ones. That is unless the edge is so thin that it starts to chip and roll.
 
Nice write up as always, I appreciate the effort and clear comparisons.
 
Just got my G10 Leek. Initial impression is... well... I'd say I'm a little bit disappointed. I think old steel handle is better.
I like stonewash finish on the blade. It looks good. Overall design, it's Leek alright. I love Leek, so there's no problem.
G10 is very grippy as others pointed out. But I've got not much complaint here.
Where my disappointment came, is this. Well, there are two, actually.
AO is sluggish and heavy to engage. With my old steel handle Leek, a slight push was enough to open the blade. But here, you must pull(or push) more decisibly. You must give it more momentum to AO to engage. I do not want lightning speed, nor feather touch to open kind of operation, but it just feels heavy compared to older one. Also, half opened blade is more of a liability than fully opened one. I've already cut my hand. (clumsy me)
Ok, AO needs firm touch to work properly, that I can live with (though I'd prefer it to engage with lighter touch), but the one thing that bothers me much is this. The lock is difficult to disengage! It's too tight. My thumb already soars after a few opening/closing. The steels are really biting and locked tight. Ok, it's good there's less chance of lock disengaing unintentionally, but still, it's too difficult to disengage intentionally!
I have to give it some time to properly worked out I guess.
I'd say it's a good knife. It's just my luck I got one with some perks that bother me. Time will tell.

That just sounds wrong to me - I suggest contacting Kershaw - who have a reputation of outstanding service - to get it corrected.

If your all steel Leek works well - there is no reason why the G-10 version should not work equally well - unless there is a fault.

For example my sample of the G-10 Leek has better action than my first all steel Leek.

Thomas W of Kershaw has visited this thread - so hopefully he can give some input.

Thank you for your concern.

I also have an aluminium handle Leek, and its AO is also a bit sluggish compared to my steel Leek. G10 one is more sluggish than aluminum one. I think I must give it some time to break in. Maybe my steel Leek is more responsive because I've used it all the time, and it is thoroughly worked out. Or, it's just my illusion. I'm quite used to my steel Leek that I use it almost without thinking. Also, my steel Leek broke its AO about a year ago. So, it's just my memory that tells me. On the other hand, other steel Leeks I have handled at the local shop recently works just fine. Yeah, I think steel Leeks are more responsive.
Anyway, the most bothersome is the lock. I think the blade tang is cut a bit too deeply, perhaps. The G10 Leek pictured in this post, has its lock engaging blade tang near the edge. My G10's lock engages halfway past the blade tang. I've always wanted the lock fully engage the blade tang, and this one does so at the expense of being too tight to disengage.
I'll give it a few days to break in. Hope it will turn out ok.

Again, thank you for your concern/suggestion.

Ah, by the way, my Leek's lock just engages at the edge even after years of use; not like your Leek's lock covering about half the tang.

Do you mean your all steel frame-lock version?
- if you go to look at the reviews I did of the 3 previous versions of the all steel (frame-lock) Leeks - they all have their locks about 1/2 way across - that's what I liked about the Leek - their apparent consistency -
but perhaps they aren't as consistent as I thought?

BTW - have you tried loosening the pivot screw a little to see if the Speed-Safe assisted opening action becomes a bit more free/speedy on your G-10 Leek?

Yes, all steel frame lock version.
I've seen your review, and you got some good ones I think. Mine is marked as Nov 03, and its lock barely touches the edge of the tang. Lock's still solid and had never failed once.
My aluminuim handle liner lock Leek has its lock engaging just like your G10 Leek.

I've brought all Leeks I have with me today to check.
AO of G10 is a bit sluggish compared to aluminium handle Leek. AO of steel Leek is broken, so I cannot compare.
The lock on G10 Leek seems to be a bit smoother than yesterday. We'll see..

I'll try to loosen the pivot screw on G10 Leek after a few days of use and if it still bothers me.

Thank you.
 
Here is the picture of my Leeks.
