Are there any combination slipjoint / friction folders?

Do you guys know of any blades (production or custom) that use a slip joint mechanism and have the extended tang of friction folders? It seems like these mechanisms could work together very well to create a tight lock up using both spring and hand pressure.

I think that's what this Fred Perrin custom douk-douk does, but haven't been able to figure out how to acquire one.

Sounds like a Case Russlock.

Like this?

Hi,

Thanks for the info. I read that that is a liner lock though: http://www.bvbranchknives.com/case_russlock.htm.

From that link: "A stainless steel liner locks the blade in place for added safety."

I'd like to avoid any type of lock because I'd like this to be a blade that I can carry around every day and in some jurisdictions locks are considered illegal.
 
If you want the extended tang for one hand opening capability, perhaps you can look at several Spyderco offerings. They have a few models out now that are one hand opening slipjoint-ish non locking knives. Offered are several somewhat expensive models, and a more reasonably priced and unique Byrd model. On these knives, "lockup" is aided by a large finger choil rather than an extended tang.
 
Thank for the tip shecky. I had looked at those spyderco's but I wasn't sure how well the extended choil would function as opposed to an extended tang for keeping it open. Also, I dig the classy look of slip joints.
 
In NYC, any knife that can be flipped open into a locked position is considered a gravity knife. So the Russlock since, one could conceivably grasp it by the blade and flick it so that the blade locks open would be considered a gravity a knife.

Since I can't carry a knife that locks I'm trying to find a really secure slip joint. I figured that a slip joint with an extended tang that I could press down like a friction folder would do the trick. I'm also looking into the Spyderco model with the extended choil. I've also got an opinel en route.

Huh. As far as I know, there are no restrictions about locks in the USA. Whether a knife qualifies as a gravity knife or not has no bearing on whether it has a lock.


p.s. - I live in Philly, so we might speak the same language, hahahaha.
 
its a love it or hate it pattern, i like it! Gave my son one and he loved it with a little practice and a few near misses its easy to open one handed:D
You cannot flick it open... not like a liner lock or anything.
cool little knife though definitely a conversation starter

Hi puukkoman:

I've read in this forum that in NYC cops will classify any knfie that you can flick open into a locked position as a gravity knife. So while a Mercator K55 is not a gravity knife it is classified as one in NYC because a person can do this with it: http://www.youtube.com/watch?v=YgHcoKG0NBc

IVANKERLEY: What if you grab the knife by the blade and flick your wrist, is it possible to open the knife that way? That seems to be the litmus test that cops here use. It's because I want to avoid that possibility that I'm looking for a slipjoint. The only locking knives I'm comfortable carrying are my Leatherman Wave and my opinel.
 
No, I've never been frisked (outside of an airport) and don't plan on it. But I'd rather not put myself in any position where I'm breking the law.

lets put it this way if the cop or you tries that your gonna end up throwing the knife or cutting yourself... there really isnt enough blade to pinch like that and its a slipjoint so the backsprings at least on my sons are typical, you should find a case dealer and handle one, ive handled my share of knives and when the clerk handed me the russlock to look over i had that moment of panic/stagefright "Uh-oh knife knut here doesnt know how to open this one"
anyway i like the pattern

Do you any reason for a NYC Cop to be checking your knife? ;)

This is an excellent point.

Back before the gum'mint had to go peeking through our luggage I would always take a small pistol when I went to New Yawk.

My friends would ask if I was afraid of getting arrested and I would always tell them, " There's no reason for a police officer to bother me, and if I am some place where I need the gun odds are there won't be any cops around."

Of course, now that The City has been sterilized into one big shopping mall this really isn't much of an issue anymore.
 
RMFNLA and Don,

I see your point, but I don't believe in making those type of assumptions. If something is illegal and can land me in jail, I'm going to try to keep from doing it even if I think the chances of getting caught are next to none.

IVANKERLEY: thanks for the clarification, I'll check one out.
