Anyone read the new Tactical Knives mag. article on the Foldair knife?Check out the web site www.mccannindustries.com They claim there are no springs.The lock has a nitrogen filled cylinder that pushes a bolt over the tang.Sort of like the Gerber Bolt lock with no spring.McCain says he got the idea from the "system that allows his shop door to close gently."The web site and the magazine has pictures of a clear handle demo model that shows the lock.The blade is made of 01 with a HRC of only 56.The magazine writes the folder will go for $200 but the web site says they made 100 folders and 90 will be sold for $400.Anyway it looks like an interesting new lock.Oh BTW they also hang a 375 lbs. Honda ATV from a hole in the blade and handle to test the lock.They said the Atv was lifted 5 times.
 
Handle looks pretty "universal aluminum handle" to me (not a bad thing neccessarily).

01 run kinda soft for a pocket knife.

No comment on price.

Can't wait for a review, though.
 
So, instead of a helical spring they're using a pneumatic cylinder. A) have their been any significant failures in knives using helical springs (Spydie's BB lock, Axis, Arc-lock, etc), and B) are there any other advantages, besides the cylinder's supposed resilience?
 
Interesting, but not necessarily an improvement from a functionality standpoint. Most people who own a hatchback or SUV with lifting rear glass can tell you that the pressurized cylinders that are used to hold the hatch open lose a great deal of their effectiveness as the temperature drops, and at other times have been known to rupture in extreme heat. All this is due to Boyle's Law, which addresses the effects of temperature on the volume of a gas. Obviously, we're dealing with a much smaller scale than an automotive application, but I'd nevertheless want to see at least a bit more information from the manufacturer regarding temperature testing that has been performed on the knives. Either way, I commend the designer for the innovative idea.
 
I've got the other two McCann knives, the Talisman and the Puffin Magnum. Very nicely done. Great Kydes, too. The Puffin Magnum is a big, heavy outdoor blade which makes sense to use O-1 for, but in a folder?

I couldn't believe that complicated mechanism is necessary, either. It's like doing it just to show it can be done, and someone will pay them for having done it.

For that money? Getasebenza.
 
For $400 you can get S30V, G10, and a Titanium framelock - but some think even that is overpriced X 2.

Once the pressure's lost it won't open or close quickly. It'll be a gas retard system - and that's not good.
