Anyone own a flush spring/joint knife?

[Ron Sabbagh]

I think the OP is talking about Everflush slipjoints. Designed by Tom Ferry and Mike Vagnino, and I think Kizer makes a few models now. I've seen pictures, but never have never held or used one.

Tyson is correct. I have still yet to find one or hear from someone who owns one

Never knew that they existed until @Tyson A Wright quantified what you were asking . What little info that I found about them just sounds like a Flush Spring When Closed and Opened . I did see a picture of one that may pass for a Traditional Slipjoint that I could get interested in . This has been an interesting thread . Thank you for starting it Ron .

I never knew this construction style existed, thanks for sharing guys.

Thanks for the kind words Old Engineer

The Everflush concept is so much more than just having springs flush when open and closed. It's an entirely different internal mechanism that changes the role of the springbar.....

here is a link to the Everflush article in BladeMagazine

Really cool but the reference ‘flush spring’ is misleading on the Everflush since the back spring in a traditional sense now becomes a cover for the hidden spring. Meaning it is no longer a flush ‘spring’ but simply a back spacer.

Thank you for sharing.

Reminds me of the Barlows that Queen used to make... (not my knife).

I'd call that one a complete fail... if your going to that much work, and on a full custom that is so much work to begin with, yet don't actually get the spring flush to the tang?

That tapered gap is hideous.
I hate the look and function of this concept to begin with. But if you're doing it, do it right.

Tony’s goal was to bring old patterns back from the grave. That being said, he did an amazing job reviving many old patterns that would still be dead and gone. What you call a complete fail and hideous is an opinion I do not understand, because the intention wasn’t to modify the original pattern. Attached is an original flush joint from the mid 1920’s and flush joints created by Tony and Reese. Sorry you do not appreciate master cutlers work bringing old patterns back to life.

I think the Kizer Zipslip is what you folks are after. I have one. Very smooth action. Use your favorite search engine.

The Youtuber at "Geared Toward Gear" hates the Zipslips. I like them for pretty much the same reasons he hates them.

Geared does not like the finger choil because it takes away from the cutting edge. He thinks the spring is too weak, making the blade too easy to close on your fingers. And he does not like that the half-stop is a bit more than half way closed.

My hands are a bit smaller than Geared's--size 7.5; perhaps that makes a difference. I like the finger choil. If my finger is in the finger choil, the blade is not likely to close. If my finger is not in the finger choil, but I am holding the handle normally and push with my thumb to close the blade, the finger choil closes on my finger. I might get a small bruise on my finger if I pushed hard with my thumb, but I don't get cut. To me, this is like closing a variety of mid-back-lock knives--I push the lockbar with my thumb, and the ricasso or finger choil falls on my finger. I like that the Zipslip is easier to close than a lot of other slip joints while it seems to me that it is safer than a lot of other slip joints. But bear in mind that I prefer locking knives that will drop closed when I release the lock.

On the other hand, Geared can open the Zipslip one-handed with his thumb. I can just barely open it with my thumb because I have trouble getting purchase on the semicircular thumb hole. But I can open the Zipslip more easily and naturally with my middle finger.

Geared bought 3 Zipslips at once and returned all of them. I bought one and might buy another.
