I don't get the hype over certain handle materials, especially g10, but any resin/plastic material that doesn't employ handle ergonomics that lock the hand in. That's not to say I'd prefer leather either as it rots and I've had rust under leather handles. My favorite, as I prefer function over form, is a cord wrap I.e. Paracord. Paracord is way more functional than any handle material I can think of, as it is multi purpose, easy to maintain the tang and has awesome grippiness. When Benchmade came out with the Adamas D2 fixed I jumped for joy that I had the choice to wrap in cord. Folders have fewer options, I understand, so I would like to see the resin handles to have a better grip pattern like volcano grips than the easily worn micro bumps most g10 handles have (think Spyderco or Emerson grip pattern). If I cant securely hold my knife then all the other properties are rather pointless. All this said, my favorite g10 handle is the Spyderco warrior as it both locks the hand in due to its shape AND it is a volcano texture and is a premium example of how to employ a resin handle correctly. Lastly, WHY, WHY, did anybody think that a pure titanium/metal grip was a good idea....oh well the makers only serve the consumers demands. Maybe consumers should get smarter and not follow fads that fail to comply with the tools primary function, that is to cut/chop and you can't do that safely if you can't grip it safely.
That's my rant. YMMV
