This opens with a direct contradiction -

I really like this knife - but I am disappointed.....

The JunkYard Dog is a frame-lock -
JYDs_GrooveLcks.jpg


The Tim Galyean designed JunkYard Dog like the bigger Kershaw JunkYard Dog II (link) I reviewed earlier has the nice round flipper - which seems less likely to catch on clothing etc.

But that's exactly what led to the disappointment -

I was excited to get the smaller handier sized JYD - with frame-lock - and I was expecting it to open like an "Unassisted assist" - much like the impressive JYD2 .....

But it didn't and I tried real hard and all the variations I knew to try to get the flipper to open without any movement/flicking of my wrist - but I just couldn't do it.

I tried adjusting the pivot screw - but it made little difference (obviously if too tight the knife would be very difficult to open - but loosening the pivot screw to the point where the blade had way too much side play still didn't do it for me). I even disassembled the knife to check there were no obstructions or debris preventing smooth motion -
nope, still couldn't do it.

In contrast to the JYD2 (and Groove) which I can open effortlessly, even when held as the most awkward angle (eg: handle vertical so to open the blade is working against gravity all the way)

To be fair I placed a call to Kershaw to check if my sample was normal - and I was told it was -

It is simply because the blade is not heavy enough to have enough inertia/momentum to fully open with method/option 1.

However I was told that most at Kershaw can open this smaller JYF without much effort - and a HINT - was to push the finger against the flipper forward - almost as if going against opening - then pull back to flip the blade open.

That worked for me first time.

However I still cannot guarantee to be able to open the knife fully every time without some, albeit small, movement of my wrist.

This is now what I do to ensure I open the smaller JYD fully - push forward against the flipper (this preloads the tension of the finger) then pull back sharply - I find when I do this there is a small movement of my wrist. If I fully immobilize my wrist - then the opening is not as reliable - especially first time right out of my pocket. So to be sure I now have to move/flick my wrist a little - although it may seem that the smaller JYD would be like "other"/ordinary flippers - but it still isn't, there is still much less effort/flipping to open the knife fully - it's just for me I still have to move my wrist a little to be sure the JYD opens fully.

This seems long and detailed but wanted to others to understand that the JYD does not open as easily as the JYD2.

hidden stop-pin like the JYD2. But looking at the photos of the front handle side - one can see the stop-pin position near the pivot.

Size comparison with the Kershaw/Ken Onion LEEK and a typical Victorinox 91mm SAK

I really do like the JYD - for its size and frame-lock - it fits and balances well in my hand, it feels sharp out of the box - perhaps not quite as stunningly sharp as the JYD2 felt - I like the Sandvik 13C26 steel.

I like it enough that it has taken the place of my Black "boron" Leek as my at home EDC...

But that doesn't prevent me from being disappointed that I can't open the knife as well as I can the JYD2 and Groove.

Vincent, thanks for the nice reviews, photos and comments you've posted on the new Kershaw models.

FWIW I disassembled my JYD2 a couple days ago and noticed that the factory lubricant was fairly viscous, about like 10W motor oil maybe. Assuming the JYD gets the same lube, perhaps a lower viscosity oil would improve the flipper action a bit. I applied just the tiniest amount of FP10 (not exactly a thin lubricant, BTW, but a little thinner than the factory oil I think) to the pivot and bushing of my JYD2 after removing excess, and it seems the action works a little more freely.

Of course IMO there's nothing wrong with a little flick of the wrist to open the knife, if it's needed. I think the fact that Kershaw recommends this says a lot about their confidence in how these knives are made. When I had my JYD2 apart, I was very impressed by the finish and fit of all parts.
 
Vincent,
Thanks for the heads on the opening problems. I have hand mobility isssues
due to arthritic operations. I will get one of their assit open models [spec Bump] instead.

Vincent your reviews here are as excellant as they are at CPF [Candlerpower Forums]....William

Thanks for the comments.

I had the JYD apart and made sure it was clean inside - I tried thin lubes like WD-40, silicone based unlocker type lube - but they made very little difference.

When I don't manage to open the JYD fully - the blade is almost always more than 3/4 open - often almost to the point of engaging the lock.

The action is adjusted so that when held horizontally and the lock disengaged the blade will fall freely under gravity - so I know there is virtually no resistance in the area where it stops.

However I can open the JYD fully quite reliably just with almost an imperceptible movement of my wrist - I would love to say there is no movement - but it's there - albeit almost invisible to anyone else.

I can actually open the JYD from its most awkward position - handle vertical so the blade fights gravity all the way -
even with my (stupid) left hand. So it's not all that "bad".

It's just that if I am not paying attention I may not open the knife fully - of course a tiny flick cures that problem - it's just that it happens most often when I first pull the JYD from my pocket - not really a good state - and I don't like that.

As long as I pay conscious attention then I don't have any problems opening the JYD, and the wrist movement is minimal - almost not there.....

My disappointment stems simply from the fact the JYD2 opens so easily - that it's astounding, the Groove's opening is not quite as stunning - but I have not had problems - and it took only a little practice.

The JYD I have had over 10 days' worth of practice and I still can't get it to open like the JYD2 or even Groove - and I don't think I ever will...
it's just physics and perhaps my over-expectation.....

Say it isn't so!!!
I want more Boron coated stuff!!! How about a Boron Random Leek?

what a nice man... :)

well this change is may be until the infatuation period is over.

I am currently really enamored with the new Kershaw Galyean designed flippers - I really like the idea of the "UNassisted assist" opening - especially on the JYD2.

Carrying the JYD around allows me to continue to practice - to see if I can get better and more reliable openings -

Although I confess the Ken Onion Speed-Safe assisted opening on the Black "boron" Leek is much easier - and it looks great - so there may be a "danger" of me reverting back after the JYD honeymoon is over.....

It was my girlfriend hobby that finally broke me of the habit of over-expectation (another passion of mine that's all about the physics. :) )

Actually I find myself doing "soft" openings on purpose with the JYD2 now that I've been carrying it for a while. Or sometimes I pinch the blade between my thumb and fingers and flip the handle open. Something about these knives just invites a lot of flicking and manipulation; very satisfying to handle.

That's why I'm bugging poor Mr. Welk to have Kershaw make a butterfly knife! :cool:

Great review, UnknownVT! Your previous reviews talked me into a Kershaw Vapor and made me hop-up-and-down happy to use a Leek (which has been borne out in use).

Many thanks for the kind words Thom.

I'm pleased to see another Leek enthusiast.

Now... since you've been impressed with the Sandvik 13C26 on the Kershaw RJ Martin Groove (also used on the JYD and JYD2) (your review - Get into the Groove! and elsewhere....) -

do you think the change from 440A to Sandvik 13C26 in the Leek is going to make much difference?

Thanks,

Have no idea, but can't wait to find out. My guess is that it'll be about the same performance-wise, but people unable to shake prejudices against 440A will be able to buy, use, and enjoy the knife without hesitation they once had.

Thank you Thom....
To me that was an invaluable comment.

I like the 440A Leek because I can get it real sharp -
its thinner blade/geometry also helps its cutting ability despite the fact its hollow ground thickens toward the edge
(actually helps cheese not stick to its face :p)

Of course being a knife knut I still very much look forward to the 13C26 Leek -
as I do like the 13C26 Kershaw uses on the JYD (JYD2 and Groove).

Thanks,

Got mine today. No need for a new thread, so here's a bump and my impressions.

Good sharpness oob, but not the sharpest Kershaw I've ever handled, shaving sharp but not all that scary. .027-.031 from the choil to the curve up, but then it quickly thickens to .040 at the very tip. I gave it a few passes per side on the CrO loaded paper and it was popping hairs. 100 cuts in cardboard and it still shaved, though roughly. A quick look under magnification showed no microchipping, and 10 passes per side had it back to approximately the same level of sharpness, best guess :p

The framelock is a small knife, too small for the pointier bits of the handle, imo. I find myself having to manipulate smaller handled knives more often while cutting, and any angular areas on the profile hotspot easily. I ground those down, though, and it feels really excellent now.

The lockbar engages at ~1/2 thickness, no failure with spinewhacks, does not travel deeper with lateral pressure (far too many liner/frame locks will go to 100% engagement with just a press of the thumb), disengages with no sticking or abrasion to the thumbpad.

The flipper works as UnknownVT says, it takes a concerted effort and lots of finger control to get the blade locked open without a wrist snap.

The backspacer is full length and plastic, not a problem for a $35 knife. The rivet pattern is stamped in the steel (news to me) and I don't mind the logos in person as much as I did in pics.

I thought the clip was a bit garish, I ground that when I reshaped the blade and handle. It's crazy tight, I might need to bend it out a bit as it is pretty hard to clip to jeans.

Overall, pretty good, though I wish it had studs. Or that they'd upgrade the Vapors just a bit.
 
I put a thumb stud on mine and then had to take the knife apart again to sink the detent ball a bit more because it bites in a bit much for the thumb but for the flipper its fine that way..

I have one I have carried for about a month. It is so sharp, I cut into a plastic bottle full of Slime and did not know it. I was just trying to cut the filler tube away from the point where it was taped to the bottle. When I started squeezing, it all came out the nice long slit I had made down the side. :o


I really like this knife, I hope Kershaw continues what it started with the nice designs and higher quality materials.

Yes, I also wondered abut the smallness of the JYD when in fact it is within a small fraction of an inch of being the same handle length as the Leek - which I have always felt was just the right length.

It is due I think to the way one's index finger falling naturally in the cut-out for the lock -
JYD -

Compare with virtually the same handle length of the Leek -
LeekHand.jpg


Note where the butt end of the knife is placed in my hand -
the Leek seems longer - simply because the index finger is further up toward the blade in a natural hold.


The flipper works as UnknownVT says, it takes a concerted effort and lots of finger control to get the blade locked open without a wrist snap.

Now that it's been over 4 weeks and most of that I have been EDC'ing the JYD - I have gotten used to its opening.......

No, I don't think I am better at it than when I reported after 10 days' worth of practice -
but now I know to pay attention when I open the knife - otherwise it is still likely I will not open it fully.

It's not the the opening that has become easier - BUT remembering to pay attention that's become more natural :o

I thought the clip was a bit garish, I ground that when I reshaped the blade and handle. It's crazy tight, I might need to bend it out a bit as it is pretty hard to clip to jeans.

Overall, pretty good, though I wish it had studs. Or that they'd upgrade the Vapors just a bit.

My sample also had a very tight clip - I simply pulled the clip up (gradually) a bit at a time until I got it to be just barely touching the handle - and the tension is just about right - however the frame-lock Leeks I have all seem to have exactly the right clip tension - for me.

Even though I'm a big fan of the Vapor - I really like the shape of the JYD blade - I wonder if the Vapor blade would work with a Galyean flipper - whether there is enough mechanical advantage and mass?

Thanks also for the input(s) from STR and 49 Pan.

BTW - and yes, the JYD is still my at home EDC.

I concur with the observations made on the flipping action of this knife and found it a small inconvenience for a knife with so many pluses. My perfect knife is the Leek utilizing premium steel but the JYD is a close second especially for the money. Sorry T.Galyean, still dont like the clip.
 
Excellent write up and images, will be trying out one of these hopefully soon!

Looking at the photos with the Leek and JYD in hand, it seems like it would be a tight fit to get all four fingers on the JYD's handle. Is that true for you?

With the Groove I found if I push the flipper straight into the handle, instead of downwards like I used to do with flippers, it opens a lot faster and with more reliability. Does this not work for the JYD?

Thanks for the photos and review. I plan to get the JYD2 as son as funds permit.
