Super solid. Super sharp!
Just got this bad boy in. This is my second Extrema Ratio, but first pocket-sized folder from them. Very impressed so far. Lockup is rock solid. No play whatsoever. I really like the adjustable compression screw on the pivot action. You can easily and quickly adjust the opening speed and resistance.
As strange as the handle looks, the ergonomics are impeccable in any hand…

position and it's actually very comfortable. The edge is fantastic right out of the box. The secondary locking mechanism is simple to use and easy to get to. The jimping is extreme, but the finish makes it very comfortable and useful.
There are a couple of...not quite flaws...but slight oddities maybe. The liner lock and secondary locking mechanism are a little lighter duty than I'd like, at least ostensibly. I imagine that they would survive more force than could practically be transferred to them, but they aren't proportionate to the heft of the rest of the knife. There is a slight choil, but so slight as to be completely useless...maybe useful for cutting your finger off. The pocket clip is a little odd in that it wraps over the end of the handle, but as far as I can tell perfectly functional.
Overall, really awesome purchase.
