Best way to check for blade play?

[snowreaper1]

I think the better work for it would be "flex." Pretty much any folder if you grab the tip of the blade and crank it left, right, up, down you'll be able to feel a very minute amount of
flex. Right now I can feel the slightest, and I mean slightest, movement in my large Sebenza and 3' Hinderer. I still consider them bank vault solid because in order to fell that slightest
movement I have to really put some torque on the tip of the blade.
I consider Blade Play to be noticeable blade wobble with little effort when grabbing the tip. And lock rock is when you put vertical pressure on the blade the lock bar flexes back and forth
and causes a clicking sound.

Open the knife, grab the blade near the tip (try not to cut yourself), and torque it around. If it wiggles or moves around, it has blade play. If it doesn't wiggle, it does not have blade play - a lot of knives have some flex in the handle, pivot, etc. if you crank on them hard enough, but I wouldn't really consider that blade play.

I put about as much torque on them as I can with my girly finger strength. I always laugh when I see Nutnfancy test for blade play...gently touch the thumbstuds with your thumb and forefinger, then proclaim that your SOG flash-2 locks up like a bank vault. Nearly every knife I've held had at least a tiny bit of side to side blade play, and that's not really a big deal for me.



I have had just a couple of knives that even I couldn't find any blade play in, even when I really torqued on them. The Hogue EX-01 and one of my Kershaw RAMs are a couple that leap to mind as having been insanely well fit out of the box.

Doing that I think I just see blade flex, the end of the blade near the pivot doesn't seem to move at all. There's no rubbing or anything like that opening or closing, I just need to stop being a jerk about it every time I buy a new knife.
