The more flush they are the easier it is to damage them, since the cutting surface is thinner.
eg
/ \ vs |\
Be sure to keep them in a safe place or you will learn the hard way when a friend tries to cut something that's too thick.
(Non-electrical people do not expect cutters to be worth $300 when they pick them up to use).
Don't get me wrong, Lindstrom cutters are awesome and will last almost forever if you cut only correct size wire, but you need to be aware that it only takes
one cut of oversize wire to cause damage.
The tip damage here is from when a friend cut something too big.
The smaller damage halfway down i didn't actually know about until i took this picture now.
And these are the semi-flush kind. So the fully flush will be even more easy to damage.
