Typically I think the lock would fail before the liners, except on an Axis lock where I reckon the liners would fail first.
You would be talking way more force than you could exert by hand on a well made knife like the Enlan EL-01.
The pivot pin on most Chinese knives is ¼” O.D. for the larger knives and 3/16ths for smaller, you won’t break or shear that with normal use. If you are in doubt then use a fixed blade. I carry a slip joint every day and feel safe enough with that, you might snap a blade at a weak spot, typically the pivot but you would have to be putting great force sideways on to the blade to do that, not really a knifey task you’d doing. I suppose it depends weather you use your knives for cutting or as a general purpose pry bar or screwdriver, not having a go - just saying that obviously anything can break if it’s not used for the intended use.
I recently bought a Hultafors Chisel knife that would take a lot of abuse before breaking, it sits in my toolbag alongside a Hultafors Heavy Duty knife, both with high carbon Japanese steel and stropped before leaving the factory. £12.90 ($19) for the pair.


Someone who was re-handling his Hultafosr Heavy duty with Curly Birch took this picture, although not full tang it’s tough enough. For £5.95 you get a carbon steel blade ready finished, very good value and probably the best quality/money balance that you are going to get. You could do the same with a Mora and ~I’m sure many have.

Strangely the Chisel knife doesn’t have a chisel grind.
Heavy duty 4” blade ⅛” thick
Chisel knife 3” blade ⅛” thick
Ideal if you want to apply high torque with a knife.
I think these two Spydercos would be strong in the pivot area.


These are more budget priced and would be plenty strong enough.


Even the G10 bolstered one would be strong enough, anyone who’s tried to break a 6mm piece of G10 will tell you how tough it is.
Don’t know where this is going but if you buy a known brand or even a lesser known one like the Y-Start knives then they are going to be strong enough for normal use.
I’ve deliberately left Frame locks until last as they are only as strong as the cut out that lets you unlock the knife and the metal that’s left there can be worryingly thin.
I’m not knocking the SanRenMu 710/7010 in fact as they go it’s a great little knife and I own a lot of them, about ten and a couple more are on the way but this pic shows how thin a framelock can get and why I wouldn’t get worried about frame locks or bolsters.


Compared to the liners on this linerlock Enlan you can see there’s enough in the thickness of the liners to give a very strong knife, no bolsters needed.
