Just a note for those planning on carrying one around, the 610 can be wrist flicked open without touching the axis lock or the thumbstud.

In some areas, this qualifies as a gravity knife or inertial opener, and may be classified as illegal.

Could just be mine, but it seems to be due to the mass of the blade overcoming the resistance.
 
Many knives are in fact like that. I can do that with most of my knives, the harder ones need to be flicked open in a fluid "S" motion. Still some cannot be opened without using the opening mechanism.
 
Most of my knives need to have the pivots loosened to do that.

This one, you just snap your wrist and bam, it's open.
 
Any axis, frame or linerlock can easily do that. So can many lockbacks. Even SAKs with practice. As James Mattis used to say in such situations, "The law is a humble beast of burden."

Mine takes a farly firm swing to open with nothing else done to assist, just slightly less effort than 4" blades of similar design. I have found that with the knife pointing anywhere resembling down, just a slight tap of the stud allows it to swing open and locked, I love it!

If concerned, tighten the pivot a bit and it should go away.

Most jurisdictions that would have a problem with gravity knives would probably find something wrong with the 4.25" blade first. :cool:
 
You can make the majority of folders out there open like that.
 
Almost any folder can be considered a gravity knife. I can flick open my spyderco delica along with all of my other knives besides SAK's and 110. This knife is almost effortless to flick out though...pretty heavy blade.

that is correct, every BM i have ever seen will do it.

and the BM 670, Spyderco Paramil, Camillus Cuda, Buck Alpha Hunter, ect., ect, ect....

You just described about 90% of nice knives.
