So, it seems like a lot of folks who buy folders like rapid deployment. I know I do.
So how about developing a standardized, reproducible, method of determining
action speed?

I think it wouldn't be hard to calculate angular velocity of blade deployment
if the camera FFS speed was standardized. This is akin to reporting barrel
velocity with guns/ammo.



Some of you engineers should take this and run with it.
 
Problem is, why do it? Difference in speed really only matters inasmuch as it makes a practical difference.

Basically, does it open so much faster that you can ready the blade and cut something more quickly than you can with a different opening mechanism.

The only devices that I've seen that really seem to make that kind of difference are the Emerson Wave feature and other, similar pocket opening devices and, if we're really being accurate, those don't so much open a knife faster as much as they open it sooner.

As an academic question it's kind of interesting, but from a really practical standpoint with most modern folders you're getiing into units of time so small that even if X folder opens twice as fast as Y folder it won't really make any difference.
 
I'd put more of a premium on reliability of opening and locking. Besides speed of opening really is dependent on operator skill.
 
I agree with both posts so far. While semi interesting, for most knives that are one hand opening, it would be hard to find a meaningful difference of speed.

And I've never once considered "speed of deployment" or "action speed" when I've purchased a folder. I know there are those that do, I just don't know how big that group is.
 
That's an excellent idea! Every millisecond counts whern you are deploying your knife...your life depends on it.

Maybe the engineers could work on ways of streamlining blades to reduce drag on them. A rounded spine should go through the air much quicker than a squared off one.
 
I don't think there is a"meaningful" difference in speed considering there are likely a lot of variables that impact blade deployment speed beyond fast and slow. Could result in less-safe knives being made and sold. I'm waiting for light sabres.

Blade speed has never been a significant condition for a purchase for me, but maybe blade speed influenced my purchased of an Italian Stilletto switch blade purchase 20 years ago. But it was more for fun and education on my part. Have never carried it or sharpened it. Pretty much a crap knife on par with Frost stuff but it works.
