Hello guys, sorry I am late to the game asking about AD20.5 variants toughness. I been checking online videos and disassembly differences. While visually I love large metal pivot and not so found of givory with unattractive “AD20.5” logo on. If I were trying to keep price down not going for full titanium then G-10 is my obvious choice.

In disassembly I have noticed the premium version of AD20.5 got no metal support liners. For titanium or aluminum metal frame, I understand no need for extra parts to keep construction simple. But is G-10 equally as tough as metal require no liner support?

The popularity of givory ver., except currently the blade material is mediocre, right now there are lots scale mod options available for folks to play, it can still be an affordable way to start.

Is G10 tough enough for the construction? Should I stop overthinking about it?
 
G10 and similar materials like FRN are about perfect for knife handles: tough, light, with a natural lubricity, resistant to most chemicals, offer good grip wet or cold, and relatively inexpensive to manufacture.

I have one like this in 3V with added Demko G10 scales from KC.

Again, what “premium version” are you talking about?

think hes putting them in 3 basic categories. grivory, g10, titanium......

saying factory g10 version doesn't have steel liners and wanting to know if they need them for strength and durability....

maybe should move thread to the Demko forum...... Mike Demko Knives MWallace Demko Knives MWallace can pitch in his thoughts on g10 and needing liners or not. since he designed and tested knives at cold steel and works at Demko now.....
 
I have the AD20.5 in S35VN with G10 and while I've not carried it nearly as much as I'd like it's still never given me a single problem. Neither has the CS American Lawman in the same combo and for a few weeks I was not kind to that knife.

The 20.5 knives in Grivory and G-10 both have nested steel liners.
From our tests during the Cold Steel era, the knives with no steel liners held an incredible amount of weight. As strong as ones with steel liners? No. But every knife regardless of lock type or construction has to have a failure point, there’s no getting around it. It’s a folding knife and sooner or later with enough weight, pressure, torque, etc. something will give. That being said a G-10 frame with no steel liners have more than enough durability for a 3” knife. But that’s kind of a moot point because they do have nested steel liners.

Totally should have realized that. In retrospect I'm not even sure how you would assemble the Shark lock without the liners. Not even sure you could.

in hindsight now that Mike talked about factory setups....I'm leaning towards some sort of aftermarket scales, the op saw, where they eliminates the liner? I'm guessing as i havent paid attention to aftermarket scales at all.....but maybe that isn't possible? I don't now without taking one apart and lookin at it.
 
I bought a set of the Berkshire Forge scales and they use the liners. They fit pretty good, but do NOT buy their hardware kit. They don't give you long enough screws for the pocket clip and there's something off in the fit of the pivot screw. The pivot can be made to work if you futz around with it and thread lock it to hell and back. The rest fits and functions enough but it felt funny having a mix. I opted for the bead blast finish but if I could do it over I would try the stonewashed finish because mine are a bit slick. Or just go with a whole different brand might be a safer bet.

That's what I thought, thanks Mike.

My full size AD20 have "less" liner than my AD20.5. Still some steel inserts around the pivot and lock, and plenty of toughness, of course. Maybe that's what the OP looked at.

I can’t answer that as I have little knowledge of any aftermarket options. There have been a few that came in for inspection and some aftermarket scales are thicker and it caused issues with original screws being too short. Especially pocket clip screws.

makes sense. I'm not aftermarket fan, so I got no idear. I feel y'all made these perfect from the factory. i only have couple of the grivory ones. i don't use them much as i prefer the larger sizes ad20s i got.

thanks for putting in your thoughts and sharing info on this, Mike. we appreciate you here.

I want to swear the pocket clip screws are just slightly longer than the rest. All the Berkshire Forge screws were equal length thus the factory screws were the fix.

I really need to carry these more often.

Some aftermarket scale vendors send longer screws for the pocket clip. The OG aluminum scales comes with those... black and plain so it works with either clip.
