I use the lock bar, so a part of the handle, to open bottles when hunting or working in the field/wood. Lately I attached a cap-lifter to my keyring, trying to grow up-I will take it off and again rely on Delica/Robin/Ladybug backlock bars.
Some FRN got scratched and I didn`t expect anything else.
I am aware this is not by all means an intended use for my knives but using the warranty isn`t an option for me, it would cost almost the knife`s value to send it in. Using the blade spine or opening device located on it seems to be too much of a risk stressing the pivot.
I wouldn`t use high end or limited production beauty to get to a sip of beer or lemonade but G10 Byrds and FRN constant production
s serve me well in that regard and, again, I am aware it is not what the knife is made for.
