Cold Steel Triple Action
I got the double edge one and it is a hoot to flip....Then you fluff the opening, the handles hit the edge ( or the point!) and put a notch in the steel that takes an hour to remove. The edge or point digs lumps out of the inside of the handles at the same time
The alloy of the handles is butter soft- the pivots wear fast, get sloppy and it's impossible to get them tight again. The whole thing gets very loose and rattly.
Even without the handles bashing the edge, edge retention on the steel is worse than the £5 Chinese Leatherman clone in my toolbox.
Also- a complete lack of any noticeable grip on the polished alloy of the handles
A shame.

Great blade in the tanto form, superb edge retention, lovely polish....the nice bits stop there.
Slop in the blade in all 3 dimensions after light usage.
Lock is wobbly and lazy too.
Handle appears to be made from the same cheap plastic they make Poundshop toys from. Horrible- with so poor a texturing that the AO action 'recoil' flipped it out of my hand more than once.
Not worth the money.
Spyderco Double Bevel-
Much smaller and lighter than I expected. Couldn't get on with the blade shape at all- I so wanted to like it after hemming and hawing for a while, but it just didn't cut well enough, despite the high sharpness. The microbevel 'transition' between the thick area and the thin areas of the blade had a noticeable step.
Plus I had the blade bounce off my thumbnail on closing a couple of times. It was going to be a case of "When" not "If" I was heading to A&E for stitches.

Blunt, couldn't get it sharp.
Utterly unergonomic.
The thumbstuds are cosmetic and the flipper action dragged.
The sharpest thing on the knife was the jimping- which actually cut me.
And that AutoLAWKs is the work of the devil- only there (to my mind) to stave off potential litigation.
Hated it.
