I have a couple of these, they perform faultlessly in Finnland which has extreme weather (as used by their "Special Forces"; just read up the Fins and their military history, hard nuts):

(Wow thats expensive, mine were under $100, which is what they are worth; designed not to break so a bit soft if anything. A work knife that you can resharpen having got mud out of tank tracks).
Similar construction handle wise. Its not going to fail, ask again in twenty years.
My first Blackjack Marauder II took a heck of a beating and has a similar moulded grip, never been an issue even after picking up the odd ding. I also have an original CS Master Tanto which is softer and that shows wear but still fine after 25 years. Its not as good a "rubber" as the Fin stuff.
I've had more trouble with screwed on scales than from moulded grips. Flippin screws come lose and often are non standard and hard to replace size wise. They are a pain. I've had some expensive stuff with screw fittings fail me: EK, Blackjack, Al Mar, to name a few. The holes are weak points.
The only moulded grip that ever failed me was a Benchmade Bushmaster made in the late 80's as the tang was short and worked itself through the soft rubber. Not going to happen with these Fin ones.
Plastic moulded is another thing altogether; I break those regularly.. Moras.
Enough from me, either you are game on and get it, or not.
